How it works
Squats before work. Legs are gone.

NicoA photo of the habit and a selfie, straight from the camera. Ten seconds and you're in.
Your partner or friends get your proof, react and leave a note. You see theirs too.
If someone is still missing, send a cheer with one tap. It feels like a push, never a call-out.
Every day with a proof adds to your streak, and the whole group keeps it alive together.
On Monday the group finds out who showed up most. A game between friends.
Day one, it's blank paper.
A week in, something starts to show.
Keep going and it comes out sharp, in full color, hanging next to your friends'.
The days you skip stay blank. Nobody makes a thing of it. They just stay blank.
Under the light, a negative turns into a proof.
Every proof fills a square. Look back and you can see the month you actually had, one photo at a time.

So every proof lands with someone who really cares.
You never have to post first to see what your people did today. Proof only asks you to show up for your own habits.
Connect Apple Health and your step goal checks off on its own. Add a photo only if you want to.
There is a ranking and a winner every week. The one who showed up most gets celebrated, and the one still missing gets a cheer.
Any proof can become a Story. Each one carries a link, so friends who see it can join your group.
Proof is coming soon to iPhone and Android. Follow @joinproof to know the day it's out.
