Pick how far back
Three to thirty seconds. Long enough to finish a rep and turn around.
A mirror that runs late.
Move. Turn around. See what you just did. PoseBack shows you a few seconds ago, continuously, so you never have to touch your phone mid-set.

The problem
You can’t watch yourself while you’re moving.
A real mirror only works when you’re facing it. Filming means picking the phone up, stopping, scrubbing back, and losing your rhythm. PoseBack removes the loop entirely: keep moving, turn around whenever you want, and the last few seconds are already playing.
Prop it up, step back
A countdown shows the live view while you walk into position.
Turn around and look
The mirror keeps running. Say “replay that” to see it again.
Why it’s different
Built for the moment you’re not holding your phone.
Hands free, genuinely
Say “replay that”, “slow motion”, “delay fifteen seconds”. Recognition runs on the phone, so it answers instantly and works in a basement gym with no signal.
Your music keeps playing
Listening for a command does not interrupt whatever you’re playing. Most voice features take the audio session and silence everything else.
Pay once
One purchase, yours for good. No subscription, no account, no sign-up.
Nothing leaves your phone.
The camera feed is held in memory for the few seconds of your delay and then discarded. It is never written to disk unless you save a frame yourself, and it is never uploaded. Speech recognition is pinned to on-device — the app refuses to fall back to a server. There is no account, no analytics and no third-party SDK.
