The hardest part of any task is starting. The 2-minute rule says: just commit to two minutes — then decide whether to keep going. Most of the time, once you've started, you'll keep working far longer. FLIP is a single-screen timer built around that idea. —————————————— HOW IT WORKS • Tap once to start a 2-minute kickoff timer. • When 2 minutes are up, flip your phone face-down to commit to a 20-minute deep-work block. • When deep work ends, turn your phone sideways to take a 5-minute break. • Hold anywhere to cancel — a segmented bar fills with synchronized haptics so the gesture is unmistakable. That's it. No accounts, no settings, no menus. —————————————— DESIGNED FOR FOCUS • Single-screen interface with a retro-digital typeface and edge-to-edge color fill that grows with the timer • Haptic feedback on every state change so you don't have to look at the screen • Lock-screen and Dynamic Island Live Activity — keep the countdown visible without unlocking your phone • A short chime when each phase ends so you can put the phone down and focus —————————————— PRIVATE BY DESIGN • 100% on-device. No accounts, no analytics, no third-party SDKs, no servers. • No data collection. The privacy policy fits on one page. —————————————— WHO IT'S FOR • People who reach for their phone instead of starting a task • Knowledge workers running Pomodoro-like sessions • Students looking for a low-friction focus timer • Anyone who wants the smallest possible app between them and beginning a task Beat procrastination by promising yourself two minutes. Then flip the phone.
