App maintenance cost: what you’ll keep paying for after launch
Last reviewed 3 November 2026
Launching isn’t the last bill. An app needs hosting, updates and fixes for as long as it’s live, and those costs surprise many founders. Here’s what they are and how to plan for them.
Expect to pay for store memberships, hosting, third-party services and developer time for updates and fixes. Usage-based costs grow with your customers, while developer time depends on how much you keep changing. List these for your app and ask your developer for an estimate, since no single percentage fits every app.
What you’ll pay for
| Cost | What it covers | What makes it grow |
|---|---|---|
| Store fees | Apple: 99 USD per membership year, which can vary by region. Google Play: 25 USD, one time | Commission on many digital sales, which grows with revenue |
| Hosting and database | The servers, data and files behind the app | More users, more stored files and video |
| Third-party services | Email, text messages, maps, notifications, analytics and error tracking | Often charged per use, so it rises with activity |
| AI usage | Calls to AI providers, if your app uses them | Every request costs money, and heavy users can cost far more than light ones |
| Payment fees | The provider’s share of each transaction | Sales volume |
| Developer time | Fixes, updates, security and support for new phones and systems | How often things change and how well the app was built |
| Domain and email | Your web address and business email | Usually small and predictable |
| New features | Improvements based on what customers ask for | Your ambitions. This is a choice, rather than maintenance, but budget for it |
Why updates aren’t optional
- Apple raises its requirements. For example, apps uploaded since 28 April 2026 must be built with Xcode 26 or later. An older project may need work before you can ship even a small fix.
- Google does the same. Google Play’s target API rules mean an app that isn’t kept up to date stops being discoverable to people on newer Android versions.
- Other software moves on. Payment providers, sign-in services and code libraries change or retire older versions, and security problems get found in them.
- New phones and screens arrive, and things that looked fine can break.
What happens if you stop maintaining it?
Usually nothing happens at first, which is why it’s easy to skip. Then problems build up: something stops working after a phone update, a security problem goes unfixed, and a quick change becomes a project because the code has fallen behind. If an Apple membership lapses, your apps stop being available until you renew it. Apple also reviews existing apps and may remove ones that no longer work or are out of date. That includes apps not updated in the last three years that get very few downloads, after notifying the developer.
How to budget
- Ask your developer for a written list of every service your app uses, and what each one charges for.
- Estimate at three sizes: today’s users, ten times that, and a hundred times. It shows which costs could hurt, and whether you’re earning enough per customer.
- Set spending alerts and limits, especially on AI and other usage-based services.
- Agree how fixes get handled: a monthly arrangement, an ongoing product team, or paying per job.
- Be careful with rules of thumb. You’ll see maintenance quoted as a fixed percentage of the build cost. A simple app with few services and a busy app with AI features won’t behave the same, so use your own list.
How to keep costs down
- Build it well first. Poor code makes every later change slower and riskier.
- Keep up with small updates, so they don’t turn into one large, risky one.
- Use automated tests and error tracking, so problems get caught early.
- Review your services once in a while. Cancel the ones you no longer use.
- Keep accounts in your company’s name, so you always see the real bills and can change suppliers.
Questions founders ask
Do I need a monthly maintenance contract?
Not always. A quiet app might only need occasional work. If customers rely on it or you’re still improving it, a regular arrangement is usually better, since someone already knows the code when something breaks.
What does it cost to keep an app on the App Store?
Apple’s Developer Program is an annual fee, as listed above. Google Play’s registration is one time. Your other running costs depend on what the app does.
My app has no backend. Do I still need maintenance?
Less, but yes. You still need to keep up with Apple’s and Google’s requirements, and your store membership has to stay active.
