Set up your phone
Good setup = honest numbers. Takes one minute.
Quick version
Put your phone down, step back so it sees all of you, and stand where it's bright.
Why it matters
The AI Coach watches 33 points on your body (like shoulders, hips, knees and ankles). If part of you is cut off, or the room is dark, it has to guess — and guesses make your numbers wrong. A one-minute setup means every rep and every score is fair.
How to do it
- 1
Lean the phone
Put it on the floor or a bag, leaning on something. Screen faces you.
- 2
Step back
Stand 6–8 feet away. Your whole body, head to feet, must fit on screen.
- 3
Light in front
Face a window or lamp. Don't stand with a bright window behind you.
- 4
Clear space
Move chairs and toys. Wear clothes that aren't the same color as the wall.
- 5
Pick a countdown
Choose 3, 5 or 10 seconds in settings so you have time to get set.
- 6
Turn the voice on
On iPhone, tap the screen once so Coach can talk. Turn the sound up.
Common mistakes
- Holding the phone in your hand — it shakes and the Coach loses you.
- Standing too close — your feet or hands get cut off.
- A bright window behind you — you turn into a dark shadow.
- Baggy clothes the same color as the wall — the Coach can't see your knees.
For parents
You don't need any equipment. A living room, garage or backyard works. Younger athletes may need help the first time to find the right distance — after that they usually do it alone.
Questions
Front or back camera?
Front camera is easiest so you can see the colors and big words. The back camera works if someone else holds the view steady on a stand.
How do I know it's right?
The setup check turns green. If it says “step back” or “move into the light”, follow it until it's green.
Does it record me?
No video is uploaded. The camera works on the phone, and only your numbers are saved.
