Senior-Friendly Gym Training Booking App

I run a small personal-training gym and need a no-nonsense mobile app, published on both iOS and Android, that lets our members book one-on-one sessions with ease. The only core feature is personal-training booking, and after any slot is reserved the app must issue a session reminder. Members will create an account and log in before they can schedule, so a simple, secure registration flow is essential. Most of our clients are 60 + years old, so the interface has to be crystal-clear: large, high-contrast buttons, uncluttered screens, and navigation that never leaves them wondering what to tap next. Four or five screens total should cover it—welcome/login, calendar, confirmation, and settings—nothing more. I’m happy for you to work in Flutter, React Native, Kotlin Multiplatform, or any other modern cross-platform stack that gets us into both app stores quickly and keeps future maintenance light. Deliverables • Complete source code with build instructions • Test builds: TestFlight for iOS and an installable APK for Android • Production-ready versions submitted to the App Store & Google Play (using my developer accounts) • A brief hand-off guide so I can adjust schedules and push updates later I’ll sign off once I can install the app, register, book a slot, and receive the reminder without my older members needing extra help.
