Proof, for the group chat

Every win generates a card built for a Story — the champion you earned, the move it took, and how long your run is.

Tap any animal in your collection to share it again, any time. It's just an image — whoever you send it to doesn't need the app, an account, or anything else.

Questions, answered

Is this a fitness app?

Not really. There are no workout routines, no rep counting and no calorie tracking. It asks one question a day — "wait, can I still actually do this?" — and gives you an honest answer. Most days it takes under a minute.

Do you store my camera footage?

No. Pose detection runs entirely on your device using Apple's Vision framework, and frames are discarded as soon as they've been measured. Nothing is recorded, saved or transmitted. The app has no server and works with no internet connection at all.

Is it free?

Yes. The daily challenge, the animals, the streak and the share cards are all free. An optional subscription adds the Trial Archive — replaying past days to collect animals you missed — and unlimited streak repair. Everyone gets one free streak repair without paying.

What if the camera can't see me?

Prop the phone two to three metres away with your whole body in frame, in a reasonably lit room. If it isn't sure, it won't fail you — the app is built to never call a good attempt a failure.

What happens if I fail today's dare?

Nothing bad. Try again as many times as you like — there's no limit and no penalty. The streak only counts days you passed.

Which iPhones does it work on?

iPhone running iOS 18 or later. On-device pose detection is doing real work, so a recent device gives the smoothest experience.

Is it safe?

Balance trials carry a genuine risk of falling, and the app says so on screen every time. Keep a wall or a chair within reach and stop if anything hurts. This is a bit of fun, not medical advice — if you have any doubt, ask a doctor first.

So — can you still?
