Mobile app maintenance and update services
App maintenance keeps a published app working, compliant and improving after launch. That means fixing crashes, updating Flutter and SDK versions, meeting new Google Play requirements and shipping regular releases. We maintain our own portfolio of Flutter apps this way.
- Monitoring
- Firebase Crashlytics, store listing checks
- Compliance
- Target API levels, Data safety, privacy policies
- Release control
- Remote config, soft and forced update prompts
- Applies to
- Apps we built and existing Flutter apps
What mobile app maintenance includes
- Monitoring crashes and fixing the ones that affect users most
- Keeping Flutter, Dart and package versions current
- Meeting Google Play target API level and policy deadlines
- Keeping the Data safety form and privacy policy accurate as features change
- Replying to store reviews with fixes, not just words
- Small improvements and performance work between feature releases
The tooling we use on our own apps
We run a portfolio of Flutter apps, so we built tooling to maintain them efficiently. You get the same approach:
| Tool | What it does |
|---|---|
| Growth config package (Flutter) | Reads app configuration from Cloud Firestore at startup; controls soft and forced update prompts, ad frequency and push notification device sync |
| Release priority tracker (Cloud Functions) | Checks every app's Google Play listing nightly and flags apps whose last release is past a warning or critical age |
| Admin panel (Flutter web) | Manages apps, privacy policies, ad settings, push templates and release plans in one place |
| Crash reporting | Firebase Crashlytics in production apps to catch problems from real devices |
Taking over an app someone else built
If your app was built by another team, we start with an audit: whether it builds, dependency health, crash data, store policy status and test coverage. You get a prioritised list of what is urgent, what is risky and what can wait. Then we agree how to proceed.

Frequently asked questions
Why does a mobile app need maintenance if nothing is broken?
Because the platform keeps moving. Google Play raises the required target API level on a schedule, Android and iOS change permission and background rules, and packages stop being maintained. An app that isn't updated can be hidden from new users or removed from the store.
Can you force users to update to a fixed version?
Yes, if the app includes an update check. Our apps read a minimum version from remote configuration, so users see a soft prompt or a required update screen without a new store release.
Do you maintain apps you didn't build?
Yes, for Flutter apps. We start with a code and store audit so both sides know the app's condition before committing to a maintenance plan.
