Your AI fitness coach for workouts that fit your life

ChattyFit creates personalized workouts based on your goals, experience, available equipment, and physical limitations.

That can include strength training, mobility, cardio, yoga, recovery sessions, or mixed workouts — at home, in the gym, or while traveling. Each workout is designed to fit your body and your current situation, not a generic program or template.

As you train and give feedback, future workouts adapt to you over time.

ChattyFit starts by getting to know you. The app asks about your body, health conditions, fitness level, and workout preferences. Based on this, your AI coach suggests the most suitable training style and builds a fully personalized training plan.

From there, you train with guided workouts that include clear instructions, videos, and images. As you complete workouts, ChattyFit adapts — future sessions automatically adjust based on your performance, feedback, and any new preferences you share.

Everything happens in a simple chat-based interface, where your AI coach can update your plan, manage your workouts, and support you as you progress.

Yes. ChattyFit is free to download and you can use the core experience with a limited number of personalized workouts each month. Optional ChattyFit Pro subscriptions unlock deeper controls (like smart exercise replacements, unlimited program updates, and priority support) when you want more power.

Unlike ChatGPT's text-only conversations, ChattyFit is a full fitness app with specialized tools that ChatGPT simply can't provide:

• Your workout plans are saved as interactive programs - not lost in chat threads
• Dedicated screens for tracking progress - browse exercises with videos and log workouts with real data
• HealthKit integration - syncs with your health data automatically
• Builds a personalized fitness profile - grows smarter with every interaction

While ChatGPT gives you advice that disappears, ChattyFit creates a lasting fitness experience.

Traditional fitness apps give you static, one-size-fits-all programs. ChattyFit is built AI-first with fundamental advantages:

• Truly personalized programs - AI creates workouts tailored to your exact needs, not pre-made templates
• Unlimited exercise variety - Access to thousands of exercises and training styles, not limited to what's pre-programmed
• Natural conversation - Ask questions, get modifications, discuss concerns just like with a real trainer
• Adaptive intelligence - Your program evolves based on your progress, preferences, and feedback
• Contextual understanding - Remembers your injuries, goals, and limitations across all workouts

While traditional apps make you fit their system, ChattyFit adapts to fit you.

ChattyFit currently runs on iPhone with iOS 17 or later. When you pair an Apple Watch running watchOS 10 or newer, the app pushes fully custom workouts directly to the Watch using Apple's Custom Workouts API, so your sessions (sets, reps, tempo, rest timers) show up natively in the Workout app without juggling extra screens.

Absolutely. Your data stays on your device with encrypted iCloud backup for syncing across your Apple devices. We never sell your information, never share it with third parties, and you can delete everything at any time. Your fitness journey is private and secure.

While ChattyFit provides professional-level guidance for most fitness needs, it's not a replacement for medical advice or specialized rehabilitation. Think of it as your always-available fitness coach that complements professional help when needed. Many users actually use ChattyFit alongside their personal trainers for better results between sessions.
