Phones down. Together. Crayp is a focus app you do with friends. Everyone holds a button, and once you're all holding, your phones lock. They stay locked until you all want out, so nobody can bail without the rest of the group going with them. We mostly use it for work sessions at coffee shops, dinners, weekend hikes, and the kind of evening where you say 'no phones tonight' and someone caves fifteen minutes in. The hard part of going phone-free isn't the first ten minutes. It's the moment one person checks Instagram and it gives everyone else permission to do the same. Crayp closes that gap. How it works: 1. Add a few friends. 2. Start a session. 3. Hold the button. Once everyone in the session is also holding, every other app on every phone gets blocked. 4. If someone needs a break, they request one and the rest of the crew has to hold together to agree. You get five minutes, then it's back on. 5. Hold to unlock when you're done. Your streak ticks up. A few things worth knowing: It runs in real time. You see your crew's hold status the second they start, so it actually feels like a thing you're doing together instead of a checklist. Breaks are unanimous. You can't sneak one — the whole crew has to agree. There's a Live Activity on your lock screen and Dynamic Island so you can glance and see phones are still down across the group. Phone numbers and contacts get hashed on your device before they ever leave it. We never see who you know. That's pretty much the whole app. Add a couple friends and try it once.
