My first app, Kartayu, is now live on the App Store (iPhone + Apple Watch). Starting a fitness journey is one task. Seeing your progress is another. Most apps show charts and numbers, so I wanted something more fun: a gamified body map. Every workout earns points for the muscles you trained, the body map paints those muscles after the session, and each muscle levels up over time. Your Apple Health workouts like runs and rides count too. Workout plans, logging on iPhone or Apple Watch, and the body map are free for everyone. The second highlight is an optional AI coach. I know there are a lot of AI fitness apps out there, so I built it only around real use cases I ran into during my own training: Machine taken? It swaps in an alternative with the same sets and reps. Feeling drained? It checks your sleep and HRV from Apple Health and suggests a lighter session. After every session, it reviews how you did and updates your next workout. It’s private first: the AI runs only on zero-data-retention providers. No ads, no tracking. The app came out of training for my treks, and it took months of hit-and-try development. The app and AI are a solo build; the designs are from a friend, for a better UI and UX. Kartayu Pro (the AI coach) is priced at the lowest I could as a launch offer, with a 7-day free trial, so you can explore it and share feedback. Any feedback helps.
