Apps do not stay healthy on their own. Every month iOS updates, SDKs change, crashes appear and small features are needed — this retainer keeps one senior engineer on your app so none of that turns into an emergency.

Each month includes: crash and bug triage with fixes, iOS/Android OS and SDK updates, dependency and security patches, App Store and Play Store releases, small feature or UI changes, and a short written report of what changed and what is coming.

You get a named engineer who already knows your codebase, predictable monthly cost instead of panic hourly rates, and priority response when something breaks in production. Larger features are quoted separately so the retainer stays predictable.
