Built my first iOS app — AI fitness app that got rejected by Apple 8 times before approval

After months of building and 8 Apple rejections, my fitness app GymFusion is finally live on the App Store.

It's an all-in-one fitness app powered by AI. Here's what it does:

\- Point your camera at any meal for instant calorie and macro estimates

\- AI workout coach that gives weight suggestions and detects plateaus

\- Take a progress photo for AI body fat estimation

\- Generate personalized meal plans based on your goals and diet

\- Full workout tracking with PR detection and volume analytics

\- Water glass scanning for hydration tracking

\- Progress dashboard synced with Apple Health

\- Recipe library with high-protein meals

The Apple rejection saga was rough. The biggest mistake? I kept uploading new builds but never actually selecting them in App Store Connect. So Apple reviewed the same broken build 8 times while I kept wondering why my fixes weren't working.

Other lessons: always enable Apple Sign-In in Firebase, make sure StoreKit product IDs match exactly (case sensitive!), and if you use third-party AI, Apple requires very specific privacy consent language including "same or equal protection" in your privacy policy.

Free to download with optional premium subscriptions and a 3-day free trial. Search "GymFusion" on the App Store if you want to check it out.

Happy to answer any questions about the dev process or dealing with Apple review.
