Calisthenics coach
A coach who watches every rep.
Prop your phone up and train. Chalkform watches through the camera, counts your clean reps and tells you, out loud, the one thing to fix. No tapping mid-set, no guessing.
Android · Australia firstHow it works
Prop your phone
Lean it against a wall or a shoe, side-on, with your whole body in the picture. The coach tells you when it can see you.
Train hands-free
It counts each rep at the top, as you reach it, and keeps track of which ones were clean. If your hips sag, you'll hear it.
Hear the one fix
Between sets you get one thing to work on, not ten. Your plan moves up when you hit the target twice in a row.
What the camera keeps
Video stays on your phone. It's never saved or sent.
The coach turns each camera frame into a stick figure on your phone and throws the picture away. Your numbers, your answers and your stick figures stay on your phone too. Read the privacy policy.
Help us test it
We're looking for people in Australia with an Android phone to train with Chalkform for two weeks before it launches, for free. Email us the Gmail address you use on your phone and we'll send you an invite.
