Gym Management App Development

I want a polished mobile application that lets me oversee every financial and membership detail of my gym from a single screen—on both iOS and Android. The two non-negotiable functions are:

• Robust membership management: add, edit, suspend or cancel members, track plan type and renewal dates, and surface quick-view analytics so I can see active versus expired subscriptions at a glance.
• Integrated payment processing: collect fees inside the app, log payouts automatically, and store a clear history that can be filtered by day, week or month for easy reconciliation.

Role-based access is essential. I should have full administrative control, trainers will have a restricted view (only what they need for their clients and commissions), and members will see their own profile, invoices and renewal reminders.

I am open to frameworks such as Flutter or React Native as long as the final result is smooth, secure and ready for App Store and Play Store submission.

Deliverables
• Production-ready iOS & Android apps
• Source code and build instructions
• Lightweight admin guide (PDF or video walkthrough)

If anything is unclear, feel free to ask before we lock the scope.
