The core Android and iOS builds are already in my repository, but key pieces are still missing before I can confidently press “publish.” Most of the UI screens are in place, yet the backend connections are only half-wired and several user flows crash during testing. I have some of the design assets—icons, colour palette, and typography files—so you will not be starting from a blank canvas, though a few secondary screens may need fresh graphics or layout tweaks to match the existing style. Your main focus will be: • Completing backend development: hook up the remaining APIs, polish data synchronisation, and ensure secure authentication. • Thorough functionality testing and bug fixing across both platforms, including edge-case QA on real devices and emulators. • Preparing the final release builds, submitting them to Google Play and the Apple App Store, and guiding me through any review feedback until both listings are live. I will provide the current source code, partial technical documentation, access to the staging server, and my developer-account credentials for store submissions. Success is measured by a clean, crash-free app that passes store review and functions identically on Android and iOS.
