ChairBreak is a ridiculously simple sit/stand timer that nags with love.

No exercises. No streaks. No leaderboards. No account. Just "stand up" and "sit down" at the times you choose — and gentle reminders when it's time to move.

Sitting all day is rough on your back. ChairBreak fixes the one thing that actually matters: getting you out of the chair on a rhythm you set, then back to work. That's it.

WHAT IT DOES
• Sit/stand cycle timer — pick how long you sit (20/30/45/60/90 min) and how long you stand (5/10/15/20/30 min). One clean timer screen with playful phase transitions.
• Work-window scheduling — ChairBreak only nags inside your work hours, on the days you choose. Evenings and weekends are yours.
• Reliable notifications — reminders arrive on time even with the app fully closed. The action button matches the move: "I'm up!" to stand, "Back down" to sit.
• Break Mode — stepping out for a walk or lunch? Pause reminders for 30, 60, or 90 minutes. End early or let it run out — either way a fresh cycle starts on its own.
• Snooze — not ready? Push any reminder five minutes.
• Set once, forget forever — a quick first-run setup for your two durations and work window, then it just runs.

BUILT TO BE INVISIBLE
ChairBreak stays out of your way. No badges to chase, no guilt, no data to feed. It respects your device's clock, adapts to 24-hour time, re-anchors after you change timezones, and picks up right where it left off if you force-quit.

WHO IT'S FOR
Desk workers, developers, writers, students, anyone at a computer all day who wants a nudge to move — without another fitness app, another login, or another streak to break.

Stand up. Sit down. Repeat. That's the whole app.
