About

Stoi Replay

Features
Read full description

Stoi is a hands-free training mirror. Your phone films the whole time and the screen plays it back a few seconds late, so you can do a skill, turn around, and watch it without ever touching your phone. It works like a mirror that runs a few seconds behind. No hitting record, no buttons between reps. Just train and look up. What you can do: • Watch your last few seconds play back on their own • Swipe to scrub through recent footage • Slow it down or pause to study a skill frame by frame • Save the last 10s, 30s, a full minute, or everything, right to your Camera Roll • It picks the best quality your phone can handle Built for gymnasts, but it works for anything where watching yourself helps. Tumbling, dance, diving, lifting, whatever you train. No account. No sign up. Nothing ever leaves your phone.
