AI fitness coach for iPhone
Get fit.
Fight better.
Tenkai is a coach that plans every week around you. It builds your training around your sport, your time and the gear you have, then plans the next week from what you actually lifted.
Your first week is free.
How was that weight?
Too light → +2 kg next week
A plan in a minute. A better one every week.
- 1
Answer a few questions
Your sport, your goal, how many days you can train, how long you have, the gear you've got and anything that hurts.

Train, log, repeat
Log your sets and how they felt. Every next week is planned from what you actually did.
Watch, then move
Every move, shown clearly
Your coach shows each move, counts your reps at the right tempo and times your rests. Every exercise has a start and end picture, and the big lifts have video.


Built for fighters
Real rounds, with a bell
Kickboxing, boxing and MMA plans build hip power, rotation and shoulder endurance, with timed rounds, a 10-second clapper and called combos. Training for running, football or just to get fitter? You get plans for that instead.

The right weight
Say how each weight felt. Your coach adds weight when you've earned it, never because you skipped the question.
A coach you can ask
Short on time? No equipment today? Sore back? Ask, and your coach changes the next workout. Swap or skip any move in one tap.
See yourself get stronger
Week streaks, personal bests and weekly volume, with reminders on your training days if you want them.
Your first week is on us.
After that, Tenkai Pro keeps your coach building every new week and lets it change your plan, starting with a 7-day free trial. Cancel any time in your iPhone's Settings.
