I’m ready to build the first-generation mobile app for our golf company and want it released simultaneously on iOS and Android. In this initial version the priority is straightforward functionality, not flashy extras. Here’s what Gen 1 must do: • Pull live information from the Google Sheets we already use for player notes and make it easy for a coach or athlete to browse and update those records on their phone. • Store and display fitness data so users can track workouts, mobility routines, and training metrics alongside their golf notes. • Let me upload short swing videos or screen-recorded tips and have them play smoothly inside the app. Access will be secured with a simple email-and-password sign-in; no social logins for now. I’ll supply the current Sheets templates, sample fitness datasets, and a handful of videos. You’ll return a cleanly coded React Native or comparable cross-platform build, ready for TestFlight and Google Play internal testing, plus brief documentation so my internal team can manage content updates. Once Gen 1 is stable we’ll roll into reservations, score tracking, and event promotion, so writing modular, scalable code is important. If you have golf-related UX experience, or previous work integrating Google Sheets APIs, please mention it—those examples will help me choose quickly.
