Free · In‑App Purchases
New in 1.6: tell ChattyFit where you are, what gear you have, and how long you've got, and your workout is set up. Plus easier swaps and your streak on Home.
ChattyFit is an AI personal trainer for iPhone that helps you plan, run, and adjust workouts around your goals, schedule, equipment, and training space.
Chat with your trainer to build a plan, ask questions during a workout, or get context-aware help from an active exercise. Attach images when a meal, equipment setup, or workout detail is easier to show than explain.
What you can do with ChattyFit:
- Describe a workout in chat, like "home, dumbbells, 20 minutes", and those choices are filled in for you.
- Swap an exercise from three alternatives, and see your streak, full history, and planned workouts from Home.
- Build personalized training plans for strength, conditioning, mobility, or general fitness.
- Run planned workouts with a redesigned active workout and exercise experience.
- Chat from a workout or active exercise without losing context.
- Attach images in chat for meals, equipment, and workout details.
- Share planned workouts with others.
- Edit your equipment and training space in your profile as your routine changes.
- Track workout history and keep your plan moving with a faster, more reliable app.
ChattyFit is designed for practical everyday training. It can help you decide what to do next, plan around your available equipment, and keep notes close to the workout itself.
