I built a focus app where your phone only locks when everyone's locks, and only unlocks when everyone agrees to stop

Been building this and finally feel good enough about it to share.

The problem we kept running into: every group study/work/hangout session starts with good intentions and ends with everyone quietly on their phones. Focus apps address this as a solo habit problem. We think it's a social one.

So I built Crayp. The core mechanic is simple: everyone holds their phone to lock simultaneously to start a session, and the session only ends when everyone agrees to stop. No one person can bail unilaterally. It's fully synchronous, both ways.

Would love any feedback, thanks
