How Much Does It Cost to Maintain an App After Launch?

Quick answer: A common rule of thumb is to budget around 15–25% of the original build cost per year to maintain an app, plus hosting and third-party services that scale with usage. That covers iOS and Android updates, bug fixes, security patches, small improvements and store requirements. Apps that keep adding features cost more, because that's new development, not maintenance.

Many founders and business owners budget carefully for building an app, then get surprised by what it costs to keep it running. Apps aren't like printed brochures. Phones update, operating systems change, servers need care and users find bugs. Here's a clear breakdown of what ongoing app costs look like, so you can plan for them from the start.

Fixed costs you'll pay no matter what

• Apple Developer Program: $99 per year, required to publish on the App Store.
• Google Play Console: a one-time $25 registration fee.
• Domain and email for support and legal pages: usually small.
• Developer tools and accounts: crash reporting, analytics and build services, often free at small scale and paid as you grow.

Hosting and backend costs

Most apps rely on a backend: a database, user accounts, file storage, notifications and an API. Typical ranges:

• Early stage (hundreds to a few thousand users): commonly $25–$300 per month using services like Supabase, Firebase or a small cloud setup.
• Growing (tens of thousands of users): often $300–$2,000+ per month, depending heavily on storage, video, images and real-time features.
• Media-heavy apps: apps that store or stream photos and video can grow storage and bandwidth costs quickly.

Good architecture choices early (image compression, caching, expiring old content) can keep these costs much lower.

Third-party services

Many apps depend on paid services that charge per user or per use:

• Maps and location APIs
• SMS verification and messaging
• Email delivery
• Payments (usually a percentage of each transaction)
• Content moderation and AI features
• Subscriptions management

Each one may be cheap at launch and significant at scale. List them all and check their pricing tiers before you build.

Operating system updates

Apple releases a major iOS version every year, and Google does the same for Android. Each release can deprecate old features, change permissions or introduce new requirements. Apple also periodically requires apps to be built with recent SDKs to accept updates. Expect a burst of developer work each fall to test and update your app.

Bug fixes and security patches

Every app has bugs that only show up with real users on real devices. You'll also need to update third-party libraries when they release security fixes. This is steady, ongoing work, usually handled through a monthly support plan or hourly developer time.

Store and policy compliance

App Store and Google Play rules change. Privacy disclosures, account deletion requirements, age ratings and content moderation rules can all require changes to keep your app listed. Missing one can mean a rejected update or a removed app.

Maintenance vs. new features

This distinction matters for budgeting:

• Maintenance: keeping the app working, secure and compliant.
• Improvement: new features, redesigns and new platforms.

Successful apps almost always keep investing in improvements, often more than maintenance. Plan both, separately.

Typical ways to pay for maintenance

• Monthly retainer: a set number of developer hours per month, commonly ranging from a few hundred to several thousand dollars depending on app size.
• Hourly as needed: developers commonly charge $75–$200 per hour in the US market. Cheaper upfront, but slower response when something breaks.
• In-house developer: makes sense once the app is a core part of the business and needs weekly changes.

Example annual budget (typical ranges)

For a small business or startup app with a modest user base:

• Store fees: about $100–$125 per year
• Hosting and backend: roughly $300–$3,600 per year
• Third-party services: anywhere from near zero to several thousand dollars per year
• Maintenance development: often 15–25% of the original build cost per year

How to keep maintenance costs down

1. Build with mainstream tools. Popular frameworks and services are easier to maintain and hire for.
2. Keep the first version focused. Every feature you add is a feature you maintain. See how to build an MVP that actually launches.
3. Own your code and accounts. Make sure your App Store account, repository and cloud accounts are in your company's name.
4. Set up crash reporting and analytics from day one. Finding bugs early is cheaper.
5. Test on new iOS betas each summer. Fixing issues before release avoids emergency work.

Warning signs your app is under-maintained

• Crash reports are climbing, but nobody is reviewing them.
• The app hasn't had an update in six months or more.
• Reviews mention bugs that have been there for weeks.
• Third-party libraries are several major versions behind.
• Nobody on your team can say where backups are or how to restore them.
• You received an email from Apple or Google about a policy or SDK requirement and aren't sure if it was handled.

Any one of these is fixable. Several at once usually means the app needs a short stabilization project before you add new features. Catching these early is far cheaper than an emergency fix the week your app gets pulled from a store or stops working on the newest iPhone.

Plan it before you build

The best time to think about maintenance is before development starts. Ask any developer you're considering how they handle support after launch, what a typical monthly plan looks like, how fast they respond to urgent bugs, and how they hand off code if you part ways. A clear answer to those questions is often a better sign of a good partner than a low build quote. Budgeting for the first year of support at the same time you budget for the build keeps surprises to a minimum.

Frequently Asked Questions

Can I launch an app and not maintain it?

For a short time. Within a year or two, OS updates and store requirements usually break something or block updates. Unmaintained apps also tend to get poor reviews.

Does a cross-platform app cost less to maintain?

Sometimes, because there's one main codebase. But framework upgrades add their own work. Our native vs. cross-platform comparison explains the tradeoffs.

What happens if my developer disappears?

If you own the code repository and all accounts, a new developer can pick it up. If you don't, you may have to rebuild. Get ownership sorted before launch.

Do I need a backend for my app?

If your app has user accounts, shared data or content that updates, yes. Simple single-device tools may not.
