Coming soon · for martial artists training at home
Perfect your technique, one rep at a time.
DojoLens is an AI coach in your phone. Prop it up in the garage, the backyard or the living room. It follows your body as you kick, checks each rep against the criteria for your belt, and tells you exactly what to fix before the next one.
First an email to confirm your address, then one when DojoLens launches. Nothing else, and you can ask us to forget your address at any time. Privacy policy

REP 4 · PRACTICE · NOTHING RECORDED
Illustration. The phone tracks body keypoints on the device. It never sees your face as a face, and nothing is recorded.
The AI coach
It sees the kick. It names the fix.
Pose AI runs on the phone itself, up to 30 times a second. Every rep is measured the moment it settles, so the correction lands while the kick is still fresh in your legs.
Your body as keypoints
The camera finds your shoulders, hips, knees, ankles and feet, frame by frame. A quick check first makes sure it’s only you, your whole body is in frame, the light is good and the phone is still.
Each rep, against your belt
Each kick is split out on its own and measured against the criteria for your rank.
- knee height at the chamber
- knee extension at the peak
- supporting heel lift
One clear fix, right away
What’s off comes back in plain words written by instructors, such as “Bring your knee up to hip height or higher before you kick out.” When a rep is clean, it says so.
Rep to rep
Closer to clean, every set.
Practise a set of front kicks and each rep gets its own verdict. Fix one thing, kick again, and watch the corrections fall away.
Sample set of ap chagi (front kick). Each correction is written by instructors and checked before it ships.
Inside the app
Phone on the floor. Hands off.
The camera turns sideways so it can see you from head to heel, and stretches run hands-free with spoken cues. Read your progress afterwards, on your own time.

Practice
Your set: 5 reps
Progress
Each stretch against how you started it. How far you stretch is between you and your instructor.
Your stretches
Seated hamstring foldScreens are mockups of the app in development, with sample data.
Train anywhere
No mirror? No partner? No problem.
All you need is a phone, a few metres of floor and enough light. Kicks and stretches, wherever you get your practice in.
Kicks after work
Phone on a stand, string lights on, a set of front kicks before dinner.
Room to move
Grass, space and the evening light, with your coach in your pocket.
Stretch, hands-free
Eight stretches from front split to cross-body shoulder, timed and spoken for you.
Privacy by design
Keypoints, not footage.
No video in practice
The practice camera has no recording output at all. Only body keypoints and measurements are kept.
