Mobile apps don't stay working by themselves. Apple and Google release major OS updates every year, and many of these updates break functionality in apps not updated to accommodate the changes. Apple deprecates APIs on an accelerating schedule — code that worked in iOS 15 may trigger App Store rejection in iOS 17. Google's Play Store policies evolve continuously, with target SDK requirements advancing every year. Without active maintenance, a mobile app will stop working, fail to install or get removed from app stores entirely.

OS Update Compatibility

When Apple releases iOS 17 or Google releases Android 14, app developers have a narrow window to test and update their applications for compatibility. We monitor beta releases months before public launches, testing your app against upcoming OS changes and implementing necessary updates before the public release. This proactive approach prevents the situation where users upgrade their OS and your app breaks — a business disruption that damages ratings and trust.

Crash Monitoring and Bug Fixes

Crashes are the fastest path to negative reviews and user uninstalls. We implement crash reporting via Firebase Crashlytics (the industry standard) and monitor crash rates, affected users and crash-free session percentages continuously. When crash rates exceed thresholds or a new crash pattern appears, we investigate and fix within 24 hours for critical issues. Our maintenance retainers include a monthly hours allowance for bug fixes and minor improvements.

Performance Monitoring

App performance degrades over time as data grows, APIs slow and code paths become more complex. We monitor key performance metrics: app startup time, API response times, memory usage and UI rendering performance. Monthly performance reviews identify degrading trends before they become user-visible problems. Performance improvements are proactively recommended and implemented as part of the maintenance engagement.

App Store Policy Compliance

Both Apple and Google continuously update their app store policies — adding new requirements for privacy, data collection disclosure, in-app purchase transparency and content standards. Non-compliant apps receive removal warnings with short deadlines. We monitor policy updates and ensure your app remains compliant, implementing required changes proactively rather than reactively after a warning.

Security Updates and Patching

Third-party SDKs and dependencies embedded in your app have their own vulnerability lifecycles. A security vulnerability in an outdated library can be exploited to compromise your app's users. We maintain a dependency inventory, monitor security advisories and update dependencies promptly when vulnerabilities are disclosed. Security audits are performed annually as part of comprehensive maintenance packages.
