Recovery-aware training
Reads HRV, resting heart rate, sleep and activity from Apple Health to compute a daily recovery score, then adjusts your session's volume and intensity to match.
Intelligent hypertrophy coach
Train by recovery.
Eat by the numbers.
Grow on purpose.
Other apps just log your workouts. MassAi closes the loop. It learns your recovery, your food, and every set you lift, then coaches your next session from everything it knows about you.

A coach, not just a tracker
Logging is where other apps stop. MassAi feeds your recovery, food, and training into one loop, then coaches the next step and explains every change.
Snap your food
Photograph a meal, scan a barcode, or count it out by the piece, egg, cherry, rasher, for fast, accurate calorie and macro tracking.
A coach that knows you
Chat or talk to a coach that remembers your goals, your history, even the shoulder that gets sore on overhead press. Its advice builds on all of it, not just today.
Private physique check-ins
Upload progress photos and get an AI physique read plus a plan built around it. Photos are processed in the moment and are never stored.
Recipes, made to fit your day
Ask for a recipe and get back a real dish with the macros worked out. Log it straight away or save it to your library for next time.
Plans you control
Reorder your training days and reshape your week whenever life shifts. The coach adapts, but the plan stays yours.
Debrief that adapts
After every session the coach reads what happened, how it felt, what you hit, and adjusts your next workout and plan.
Progress you can see
Track bodyweight against your goal with trend charts, so you know the plan is working, not just what you lifted today.
Built for muscle
Every recommendation is tuned for hypertrophy: progressive overload, real recovery, and the protein to back it up.

Debrief and adapt
After each session the coach reads what happened and adjusts your next workout and plan.
Then it repeats. The more you train, the better it knows you.
Questions
Is the coach a real person?
No. Coaching, plans and analysis are AI-generated by large language models, not a human coach. It's a powerful assistant, and you stay in control of your training.
Do you store my photos?
No. Food and physique photos are sent for analysis in the moment and are never stored on our servers.
What platform is it on?
MassAi is built for iPhone, with Apple Health integration for recovery tracking. Download it from the App Store to get started.
Is this medical advice?
No. MassAi is a fitness and educational tool, not medical advice. Always consult a qualified professional before starting a new training or nutrition program.
How accurate is the food scanning?
AI photo and barcode scanning produce calorie and macro estimates to make logging fast. You can always adjust the numbers.
