One-leg balance test
Your phone's camera times it. Free, no sign-up.
- The clock stops when the foot comes down
Stand next to a wall or counter
How to do it
- Stand next to a wall or counter, near something you can grab.
- Prop your phone up and step back 2–3 m, so all of you is in the frame.
- Lift one foot and rest it behind your other calf.
- Keep your arms by your sides and look at one point ahead.
- The clock stops when the foot comes down.
No room to step back? Choose Time it myself and hold the button for as long as you stand.
How long is good?
10 s
10 seconds is a common benchmark in balance research. The test times up to 45 seconds, so there is a top time to aim for.
Why let the camera time it
- Hands free. The clock starts when your foot lifts and stops the moment it comes down. No stopwatch, and nobody counting for you.
- Private. Your phone reads your pose itself. The video never leaves it.
- Fair. Everyone is timed the same way, which matters once you dare a friend.
Dare a friend
After your hold, tap Dare someone. It makes a link with your time on it. Your friend opens it, sees your time and takes their own turn, and the board shows who lasted longest.
Questions
Do I need an account?
No. Open the test and start. You can keep your time with an account afterwards if you want to.
Is my video uploaded?
No. Your phone reads your pose itself, and the video stays on your phone.
Can I use it inside Instagram or TikTok?
Yes, it asks for the camera there. If the camera is refused, open the link in Safari or Chrome.
Do I have to install anything?
No. It runs in the browser.
Is this a medical test?
No. Maii is not a medical device. Stand near something you can grab, and stop if you feel unsteady.
