What We Build
Platform Options
**Cross-Platform (React Native)** - Build once for iOS and Android. Access Apple Health and Google Fit from one codebase. Recommended for most fitness apps prioritizing reach. **Native iOS (Swift)** - Best for premium fitness apps targeting Apple Watch integration, HealthKit features, or iOS-focused audiences willing to pay premium prices. **Native Android (Kotlin)** - Optimal for Android wearable integration (Wear OS) or fitness apps targeting price-conscious or global Android-heavy markets. **Our Recommendation:** React Native for fitness apps. Most users want data on their primary device regardless of platform. Focus development on features and personalization rather than platform-specific code.
Tech Stack
**Frontend:** React Native with TypeScript for cross-platform fitness UI **Backend:** Node.js with Express for workout plans, user progress, and analytics **Database:** PostgreSQL for user data, workouts, and progress tracking with time-series optimization **Health Integration:** Apple HealthKit and Google Fit APIs for activity data aggregation **Wearables:** Integration with Fitbit, Garmin, Whoop, and other fitness trackers via APIs **Video Streaming:** Cloudflare Stream or Vimeo for workout video delivery **Push Notifications:** Firebase Cloud Messaging for workout reminders and streak alerts **Analytics:** Mixpanel or Amplitude for feature usage, retention, and workout completion tracking
Why Build Custom
**No-Code Limitations:** Fitness app builders lack sophisticated workout progression algorithms, wearable integrations, and unique features that differentiate your coaching methodology or program. **Performance Requirements:** Smooth workout video playback, real-time rep counting, and responsive UI during active workouts require native performance that template platforms can't match. **Unique Training Methodology:** Build features specific to your fitness approach - custom exercise libraries, progression models, periodization schemes, or coaching communication that generic platforms don't support. **Full Ownership:** Own your fitness IP and member relationships. No revenue sharing. Control pricing, content, and features without platform limitations or monthly fees.
