Complete Fitness App Development Using Flutter
Budget: $250 – $750 AUD
I have an Android APK for my app Routivise, a personalised health and routine planner that includes features like workouts, recipes, mood tracking, and routine generation. The UI is designed and mostly built (Flutter or FlutterFlow), but:
Buttons aren’t functional
No AI or backend logic is implemented
Not yet exported for iOS (only have APK)
What I Need You To Do:
1. Complete Button + Page Functionality
Make all buttons work (Start Routine, Generate Workout, Log Mood, etc.)
Ensure smooth navigation between all app sections
2. Integrate AI (GPT-4 or GPT-3.5 via OpenAI API)
Add personalised AI functionality:
Routine generation (based on goals, habits, energy)
Workout generation (goal-based, equipment/no equipment, time-based)
Recipe generation (calorie-based, macro-specific, meal-type)
AI should respond dynamically to user preferences and goals
3. Include Large Content Library
Add a wide variety of prebuilt workouts and recipes:
100+ workouts (bodyweight, gym, home)
100+ recipes (healthy meals, quick options, macro-focused)
Content should be well-organised (tags, filters by goals, etc.)
4. Firebase Backend Integration
Authentication (Email + Google Sign-In)
Firestore to save:
User preferences
Generated content
Mood logs and goals
Cloud Functions (if needed) to trigger AI tasks
5. Export to iOS & Android
Final APK for Android
IPA for iOS (TestFlight-ready)
Optional: help upload to App Store & Google Play
6. (Optional) Subscription Integration
Basic Stripe or Firebase setup for handling subscriptions in future (can be scaffolded for now)
Deliverables:
Fully functional app (APK + IPA)
Source code with documentation
Firebase project live and connected
AI fully working and generating relevant content
Built-in recipe & workout library
Deployment help (if needed)
Tech Stack:
Flutter / FlutterFlow
Firebase (Auth + Firestore)
OpenAI (GPT-3.5 / GPT-4 API)
Stripe (optional)
Xcode for iOS export
Ideal Developer:
Strong experience with Flutter apps
Has integrated OpenAI before
Can export for both iOS and Android
Bonus: Past work on fitness, wellness, or lifestyle apps
