Guided Breathing App Development

I’m ready to turn a clear concept into a polished mobile experience on both Android and iOS. The core of the app is guided breathing exercises delivered through engaging video instructions. I need a developer who can build the full flow—from the welcome screen straight into an intermediate-level exercise library—while keeping the interface clean, calming, and distraction-free.

Key points I already know I want:
• Cross-platform codebase so we maintain one design, one backend, and consistent performance in the App Store and Google Play.
• A modular video player that can loop or advance automatically as each inhale, hold, and exhale segment completes.
• A simple progress indicator and subtle haptic cue so users stay focused on their breath rather than the timer.
• Space in the architecture to add beginner or advanced levels later without overhauling the database or UI.

I will provide the exercise scripts, the video clips, and brand assets; you’ll handle coding, basic UI animation, and publishing support. Clean, well-commented code (React Native, Flutter, or a similarly efficient framework) and a short hand-off document are part of the final deliverable. If you have previous wellness or meditation app examples, please include them so I can see how you approach smooth transitions and calming aesthetics.
