Flip phone to shhh..shush!
Focus on your life, not your phone! Flip phone to shhh (or shush)..
It's that easy. Just flip your phone screen down, wait 2 seconds, and no more distractions. Pick it up and be instantly available.
Minimal battery impact and super easy to use.
CAUTION: The app will not work reliably for users with a virtual proximity sensor - some manufacturers fake the proximity sensor with a touch sensor instead of a real proximity sensor!
