Somebody has offered you app maintenance services. You own one application that works, you did not write it, and the offer wants a monthly signature on a bundle nobody has itemised for you.
Seven sellers’ own maintenance pages from the first page of Google were read for this article, plus one more seller’s published guide. Five of the eight print a figure, and only one of the five writes a plan that fits a single small application: the cheapest published band on the whole set is aimed at an app with minimal or no back end and fewer than ten thousand users. Every other ladder opens at a level that assumes a company with an estate of software and a queue of tickets arriving every week.
A package is three things sold under one price: upkeep nobody else will do for you, monitoring you are probably already paying for somewhere else, and a promise about how fast a person answers. This page opens the packages, prints what each seller charges, names the unit each one counts, and marks the lines an owner with one application can leave on the table.
The package contents and the monthly figures on this page were read on 1 September 2026 off seven sellers’ own maintenance pages taken from the first page of Google for app maintenance services and for mobile app maintenance services, plus one further seller’s published maintenance guide, with an eighth ranked page refusing an automated read; every figure below is printed with the seller’s name, the tier name that seller gives it, and the day it was read.
None of these sellers is linked here. They sell app maintenance and support services next to the work I do, so each is named here with its address in plain text and no link.
What is actually inside an app maintenance package?
A package is three kinds of work in one price: jobs that arrive on somebody else’s schedule, jobs that arrive when something breaks, and jobs that only exist because you asked for them. Every contents list read for this page carries all three, in different proportions and under different names.
Which jobs arrive whether or not anybody touches the application, item by item, is listed on its own page; this one is about what a seller puts in a package and charges for.
| Seller | The tier they name | What that tier lists | Read |
|---|---|---|---|
| Foresight Mobile | Essentials | Core OS updates and compatibility, critical security patches, uptime monitoring, a dedicated Slack channel | 1 Sep 2026 |
| Bolder Apps | Basic Maintenance | OS compatibility, store compliance, security patching, bug fixes, crash monitoring, SDK updates | 1 Sep 2026 |
| ScienceSoft | L2 support | Configuration fixes on client and back end, app-server synchronisation, logging issues that need code changes | 1 Sep 2026 |
| CAST Software | Mobile AMS, no tier named | Crash monitoring, security reviews, integrations, performance monitoring, analytics, source code versioning, vendor monitoring | 1 Sep 2026 |
Read the four lists side by side and the same skeleton shows through all of them.
The first kind of work arrives on somebody else’s calendar. Apple and Google change what a published app is allowed to do and set a date. A dependency releases a version and stops patching the old one. A certificate expires. A signing key rotates. None of it is triggered by anything you did, none of it can be postponed indefinitely, and all of it is genuinely somebody’s job. Foresight Mobile’s Essentials tier at foresightmobile.com/services/app-support-and-maintenance names core OS updates and compatibility for iOS and Android first, ahead of everything else. Bolder Apps’ base tier at bolderapps.com/blog-posts/mobile-app-maintenance-services-2026 covers the same territory as OS compatibility, App Store and Google Play compliance, security patching and third-party SDK updates.
The second kind arrives when something breaks. Bug fixes, crash monitoring, incident response. Every list has it and every list is vague about it, because nobody can say in advance how much of it there will be. This is the part of the price that is insurance, and like insurance the seller is pricing your expected volume rather than your last quiet month.
The third kind only exists because you asked. Foresight Mobile’s Premium tier names dedicated feature development hours per month; Bolder Apps puts small feature additions and A/B testing infrastructure into Standard and Enterprise. This is development work with a monthly wrapper on it, and it is the part of a package most likely to be sold on the strength of the first two.
CAST Software’s glossary page at castsoftware.com/glossary/application-maintenance-services-support-ams-mobile-web publishes the longest contents list on the whole result set and no price at all: app crash monitoring, security reviews, integrations, performance monitoring, analytics, source code versioning, vendor monitoring, bug fixes at code or surface level, end-user experience evaluation, cloud migration assistance and platform migration support. As a description of everything that can be sold under this name it is the most complete one available. As a shopping list for one application it is unusable, which is a fair summary of the category.
An application an AI tool wrote also gets harder to change every week it runs, and the reason the work keeps arriving has more to do with how the code was assembled than with how many users it has.
What app maintenance services cost when a seller publishes a number
Monthly figures read on 1 September 2026 run from ScienceSoft’s $400 for a simple mobile app, a band it defines against minimal back end and under ten thousand users, up to Bolder Apps’ $50,000 and above for an enterprise tier. Every other dollar ladder below opens at $2,000 a month or more, and the only ladder not priced in dollars is Foresight Mobile’s.
| Seller and page | Tier as the seller names it | Published price | Read |
|---|---|---|---|
| ScienceSoft, mobile maintenance page | Simple mobile app, monthly | $400 to $1,500 | 1 Sep 2026 |
| ScienceSoft, mobile maintenance page | Mobile app of moderate complexity, monthly | $2,000 to $8,000 | 1 Sep 2026 |
| ScienceSoft, mobile maintenance page | Complex apps, monthly | $4,000 to $30,000+ | 1 Sep 2026 |
| ScienceSoft, mobile maintenance page | L1 support for end users | From $10.50 to $14.40 per ticket | 1 Sep 2026 |
| ScienceSoft, mobile maintenance page | L2 support for end users | From $33 per ticket | 1 Sep 2026 |
| Foresight Mobile, app care page | Essentials | From £675 a month | 1 Sep 2026 |
| Foresight Mobile, app care page | Standard, marked Most Popular | From £995 a month | 1 Sep 2026 |
| Foresight Mobile, app care page | Premium | From £1,495 a month | 1 Sep 2026 |
| Foresight Mobile, app care page | Onboarding, one time | £500 to £1,000 | 1 Sep 2026 |
| Bolder Apps, maintenance guide | Standard Maintenance | $5,000 to $12,000 a month | 1 Sep 2026 |
| Bolder Apps, maintenance guide | Enterprise Maintenance | $12,000 to $50,000+ a month | 1 Sep 2026 |
| Bolder Apps, maintenance guide | Retainer with Feature Budget | $8,000 to $30,000 a month | 1 Sep 2026 |
| Radixweb, application maintenance page | Typical monthly package, stated in its own FAQ | $2,000 to $10,000 a month | 1 Sep 2026 |
| Trango Tech, app maintenance and support page | Monthly maintenance, stated in prose | $3500 per month, printed without a comma, up to $55,000 | 1 Sep 2026 |
Foresight Mobile is a British seller and prices its app care plans in pounds. The ladder above is its care plan ladder, separate from the fixed-price planning service the same company sells, which is not a maintenance price and is not printed here.
Bolder Apps names a cheaper entry tier below the three above. That figure, and what a year of it comes to, belongs to the page that prices what maintaining an app costs, so it is not printed twice.
Radixweb’s number needs reading carefully, because the page states it as what this work typically costs rather than as Radixweb’s own price. The sentence sits in the page’s own FAQ markup, read directly from the source at radixweb.com/services/application-maintenance on 1 September 2026. Trango Tech’s sentence at application.trangotech.com/app-maintenance-support-services/ works the same way: a range in prose, attached to no tier, covering the whole spread between a small application and something enterprise-sized.
Three pages opened for this article carry contents and no price at all.
As of 1 September 2026, CAST’s application maintenance services glossary page does not render a price for the service to an automated read.
As of 1 September 2026, Softjourn’s application maintenance services page at softjourn.com/application-maintenance-services does not render a price for the service to an automated read, and its page source, read directly, carries no price either.
As of 1 September 2026, FlairsTech’s application maintenance guide at flairstech.com/blog/application-maintenance-service-guide does not render a price for the service to an automated read.
Softjourn and FlairsTech are the pair worth noticing. Both quantify what going down costs. Softjourn’s page says unexpected downtime “can cost your business up to $5,600 per minute in lost revenue and damaged reputation”; FlairsTech’s guide attributes to the Ponemon Institute an average cost of downtime of “$9,000 per minute”. Two pages on the same result set, two different figures for the same idea, and neither quantifies what the service costs. A further ranked page, SolGuruz’s mobile app maintenance guide at solguruz.com/blog/mobile-app-maintenance-guide/, returned HTTP 403 on 1 September 2026 to both a plain fetch and a raw request with a browser user agent, so nothing about its contents is claimed here.
Several of the pages that publish a range also publish a share-of-build rule for working out an upkeep budget. That rule is left where it is.
Nobody prices your upkeep off a build invoice you never received.
A share of what you paid to build the thing only works as a number if you paid to build the thing. The ladders above are not put together that way in any case: every tier on them is defined by complexity, user counts and ticket volume, which is what the seller is actually pricing.
None of the figures above is your whole monthly bill. Hosting, the database, the metered services and the builder subscription are counted somewhere else and are never added up again here.
The units app maintenance and support are sold in, and why none of them is your app
Every seller has to pick something countable to price, and the four units in use across these pages all count events rather than applications.
| The unit | Who prints it | What it counts |
|---|---|---|
| A ticket | ScienceSoft | 200 to 300 L1 tickets a month, or 40 to 160 L2 tickets a month |
| A priority level | Radixweb | How fast somebody answers, from 15 minutes to one business day |
| A calendar month | Foresight Mobile, Bolder Apps | Availability, whether or not anything happens in it |
| A pull request | Code review sellers | Changes to the code, one change at a time |
Read the volumes in the first row again. ScienceSoft’s per-ticket pricing at scnsoft.com/application/mobile/maintenance-and-support assumes between two hundred and three hundred first-line tickets a month at 24/7 coverage, and between forty and one hundred and sixty second-line tickets at 8/5 coverage. Those volumes describe an application with a support inbox and staff reading it. A working application with a few dozen paying customers might generate three tickets in a quarter, and it will never be priced sensibly by a unit built for that volume.
The priority level is a different kind of unit. Radixweb’s rendered page publishes a four-level grid running from a fifteen-minute first response and four-hour resolution for a critical failure down to one business day for cosmetic work. What that grid prices is how quickly somebody picks up, not what they then do. If your application going down for an afternoon costs you a few annoyed emails, you are being sold a fifteen-minute response you have no use for.
That is easy to dismiss until you are the person waiting. Somebody in a builder community wrote about being stuck on a support ticket that involved moving a domain and a live production integration, unable to do anything at all until it was answered. That is what a response-time promise is for, and it is worth real money to whoever needs it. The question here is whether it is worth real money to you, every month.
The calendar month is the loosest unit of the four, and it prices availability. Foresight Mobile and Bolder Apps both sell it, and both are honest about what it is: a share of an engineering team held ready, whether or not anything happens in the month you paid for.
The fourth unit is the interesting one for an application somebody else’s tool wrote, because it is the only one that counts changes rather than events. Code review sold by the pull request is the one recurring service in this territory whose published monthly price moves with how many changes go in, which is the thing that actually generates risk in an AI-built application. Those figures belong on that page and are not repeated here.
Which lines a founder with one app can cut
Sort the contents lists from the first section into three piles: work you are already buying somewhere else, work nobody else will do, and work that exists because the seller has capacity to fill.
You are almost certainly already buying:
- Uptime monitoring. Foresight Mobile names it outright, and two of the other three lists sell crash or performance monitoring in its place. It is also a thing you can have watched without paying somebody by the month for it, and if your host already alerts you when the application stops responding, you are buying it twice.
- Hosting-side backups. Managed database platforms take them. Check whether yours does and how far back they go before you pay a second party to promise the same thing.
- Crash and error reporting. The free tier of a hosted error tracker covers one application with a few thousand users comfortably, and being told when something breaks is a separate purchase from having somebody fix it.
Nobody else will do:
- Store and platform deadlines. Apple and Google publish dates by which an app must be built against a newer toolchain or lose the ability to ship updates. Missing one is a wall rather than a slow degradation. The costs and accounts involved in publishing to the stores are set out separately.
- Dependency and framework updates. These are the ones that stop being safe long before they stop working, and they are also the ones most likely to break something on the way in. What to do when a dependency update goes through and the application stops is a job in its own right.
- Expiring keys and certificates. A renewal nobody owns is a scheduled outage with a date on it.
Then there is a category the package lists barely touch: whatever the generator left behind. Of the 21 third-party applications in the set of 26 audited in June and July 2026, one had a leftover function sitting in its database that would run whatever database command it was handed. The application itself no longer called it, and it was still reachable by anybody holding the key the app hands out to every browser. No amount of uptime monitoring finds that, no crash reporter fires on it, and no priority level covers it, because nothing about it is an incident until it is.
Somebody describing their own live applications in a builder community said plainly what a package would be arriving at:
I’ve made about 20 apps, some in production for actual real businesses and I never wrote a test in my life…
That is not a person shopping for a monthly plan. It is a fair description of what a lot of working AI-built applications are underneath, and it explains why the lines a package leads with are rarely the lines that matter for one. Elsewhere, a person running a load-bearing internal tool that thousands of people depend on describes themselves as the only one keeping it going, and says the upkeep now runs through the same kind of assistant that built it. Neither situation is what a tier list was written against.
App maintenance companies, shops and one person: who actually sells this
An app maintenance company is usually a development shop selling its bench time between builds, which is why its tier names read like the tier names on its build pages. Of the nine results on the first page for this phrase, one is a glossary and one a third-party ranking.
The rest are sellers’ own service pages and published maintenance guides. The ranking is somebody else’s list, not a page any seller wrote, so nothing in it is quoted and it carries no link. Of the eight ranked pages fetched for this article across that result set and its mobile variant, four print a figure, three print none, and one refused an automated read.
What is missing from that census matters more than what is in it. Nobody on the first page sells app development and maintenance to a person who owns one application and no developer. They address a reader with a department, or at minimum a counterpart on the seller’s side who can hold a weekly call. That is a description of who the market is for rather than a complaint about the sellers.
Three shapes are actually available. An app maintenance company, in the sense the ranked pages mean it, is a firm with a support desk, a ticket system, priority levels and a minimum commitment; Foresight Mobile asks for three months initially and then rolls monthly. The arrangement survives an individual leaving, and you pay for the desk whether or not you use it. A smaller shop or a single person is the other end: cheaper, more responsive, and it concentrates everything about your application in one head. That is a real risk and also, for one small application, frequently the right trade. Deciding you want somebody on hand every month, and finding that person, is a different job with its own starting sequence.
The third shape is somebody taking the whole thing. If what you want is for one person to own the application outright rather than to answer tickets about it, handing the application to somebody who keeps it running is a different transaction with different questions attached.
One owner in a community thread described having client sites offline and no answer from anybody for days, and concluded they had to move. Whichever shape you pick, the failure mode is the same: the arrangement works exactly as well as the responsiveness behind it, and no tier name tells you what that is.
What an app maintenance service for startups actually needs to be
An app maintenance service for startups means a right-sized version of the same thing: somebody who takes the deadline work, answers when something is genuinely broken, and does not charge for a support desk that will sit idle. Nothing on the first page of Google is sold in that shape.
Someone in a small-business community asking about applications built with AI tools wrote the line that sorts this whole territory:
Would love to hear from people who actually run a business, not just people experimenting with AI builders.
That thread was asking business owners what actually happened after launch, and whether the thing was still maintainable half a year on. The distinction it draws is the one that matters here: if you have paying users the deadline work is not optional and somebody has to own it, and if you are still experimenting almost none of a package applies to you yet.
For the reader with paying users and no developer, a right-sized arrangement contains four things. Somebody watching the platform and dependency deadlines and saying so before they arrive. A named person who will look when something breaks, with an honest answer about how fast that is. Access to the accounts and the code that does not depend on that person staying. And a way to buy a change when you want one, with no monthly commitment attached.
It does not contain a priority level grid, a share of a monitoring stack, a feature-hours allowance you will not spend, or a minimum term. A business owner building an internal system asked whether they would also need somebody on hand to watch over it once other people were paying to use it. Somebody does have to own the deadline work, and that is a smaller commitment than the packages on this page are built to sell.
What a monthly agreement should promise about hours, what rolls over and how fast somebody answers is a decision with its own rule. What the whole month adds up to once the parts nobody sells you are counted is worked out separately. And whether a monthly plan is even the right one of the four ways of keeping an application alive is the question that comes before this page.
Buying help one job at a time instead of by the month
Buying per job means giving up four things a package sells: a share of somebody’s monitoring stack, a place in a ticket queue, a response-time promise, and an allowance of feature hours. For an application with a handful of paying users, all four are cheaper to replace than to rent.
The monitoring stack you replace with the free tier of a hosted uptime checker and whatever your database platform already backs up. The ticket queue you replace by having one person’s contact details. The feature-hours allowance you replace by paying for a change when you want a change, which is what one repair bought on its own costs rather than what a month of availability costs. The response-time promise is the one that genuinely costs you something to give up: paying per job means that when something breaks on a Friday, you find out then whether anybody is free.
The case for paying per job is arithmetic about frequency rather than a complaint about packages. A package priced against two hundred tickets a month is a bad deal for an application that generates two a quarter, and apart from the one simple-app tier named above, every published ladder read for this page is priced against volume a single small application does not produce.
The case against is real too. Deadline work does not announce itself, so if nobody is watching the platform notices and the dependency advisories, per-job buying becomes nobody buying anything until something breaks, which costs more than either option. Somebody has to own that calendar, even if most months the only thing they do is confirm there is nothing to do.
There is no package here and nothing to sign up to.
Common questions about app maintenance services
What do app maintenance services include?
Across the four contents lists read for this page, app maintenance services include operating system and platform compatibility updates, security patching, dependency and SDK updates, crash and uptime monitoring, bug fixing, store compliance work, and in the higher tiers a monthly allowance of feature development. CAST Software’s list adds integrations, analytics, source code versioning, vendor monitoring and migration assistance. No two sellers use the same tier names for the same contents, so comparing two packages by tier name alone tells you almost nothing.
How much do app maintenance services cost each month?
All of these came off the sellers’ own pages on 1 September 2026. ScienceSoft puts a simple mobile app at $400 to $1,500 a month, a moderately complex one at $2,000 to $8,000, and a complex one at $4,000 to $30,000 and above. Foresight Mobile’s app care plans start from £675, £995 and £1,495 a month across three tiers. Bolder Apps publishes $5,000 to $12,000 for Standard and $12,000 to $50,000 and above for Enterprise, and Radixweb’s own FAQ names $2,000 to $10,000 a month as typical. What the whole month adds up to once the parts nobody sells you are counted is worked out separately.
What is the difference between app maintenance and app support?
Two of the sellers read for this page price them as separate levels, which is the clearest answer available. ScienceSoft sells first-line and second-line support as per-ticket work, meaning somebody receiving, logging and answering user requests and fixing configuration problems, and puts code changes into a third level. Radixweb sells response and resolution times against priority levels. Support, in both, is the answering. Maintenance is the work that happens whether or not anybody writes in: platform updates, patching, dependency renewals. Mobile app support and maintenance services sold as one bundle contain both, usually priced against the answering.
Is a software maintenance service the same thing as an app maintenance service?
Usually not in practice, even though the words are interchangeable. On 1 September 2026 the results for software maintenance services and the results for app maintenance services shared no URL, and two sellers who appear on both ran separate pages for each. Software maintenance and support services are written for enterprise IT estates: many internal systems, integration layers and vendor contracts. If you own one application with users, the app-side sellers are writing for something closer to your situation, even when they are still writing above it.
I call mine a site rather than an app. Is this page for me?
Partly. If the thing you own has accounts, a database and payments, then everything on this page applies to it regardless of which word you use, and web app maintenance services are sold from the same pages as mobile ones by most of these sellers. If it is a handful of pages that describe a business, the sellers and the numbers are different. What it costs to keep a site with a handful of pages going is a different bill with different sellers behind it, and it is worked out on its own page.
My app works today. Do I need a plan at all?
Not necessarily, and the test is frequency rather than size. Ask how often the application needs to change, and how long it can be degraded before that costs you something real. If the answers are rarely and a day, a monthly plan is buying availability you will not use. What you still need is somebody owning the platform and dependency deadlines, which arrive on a schedule you do not control and are the only part of this territory with a hard date attached.
What does a priority level mean on a support plan?
It is a promise about speed, not about outcome. Radixweb’s rendered grid, read on 1 September 2026, sets a fifteen-minute first response and a four-hour target resolution for a critical failure, an hour and a day for a major feature being unavailable, four hours and seventy-two hours for a non-blocking defect, and one business day for cosmetic changes and enhancement requests, with resolution in an agreed sprint. Worth noting: the same page’s FAQ markup words the slowest tier differently, saying low-priority issues are addressed within three business days. What each level actually promises, how many hours come with it and what rolls over from month to month are terms inside the agreement rather than features of the tier, and they get read separately.
Does a maintenance package cover new features?
Only in the higher tiers, and only as an allowance. Foresight Mobile puts dedicated feature development hours per month into its Premium tier and not into the two below it. Bolder Apps puts small feature additions into Standard and Enterprise, and sells a separate arrangement it calls a retainer with a feature budget at $8,000 to $30,000 a month. Below those tiers, a new feature is quoted as its own job on top of the monthly fee. If the reason you are shopping is that you want changes made, read the tier you are being offered for the word hours before you read it for the word maintenance.
Do these companies work on an app that an AI tool built?
Most will take the work, and none of them writes for it. Every contents list read for this page assumes an application a team built deliberately, with a repository somebody understands and a deploy process somebody set up. An application assembled in a builder arrives with different problems: leftovers nobody removed, no tests, access spread across accounts opened one at a time. The companies that build applications with AI tools and then sell care for the model afterwards are selling something different again, and what those six pages published about price is worth reading before you assume a maintenance seller covers your kind of build.
Owning an app means being able to run it, change it and recover it without guessing. The sprint below leaves you with the runbooks and documentation to do that.
