What's inside
Built for real users
Smart Timer Engine
A finite state machine that persists across crashes. Survives restarts, dynamically adjusts when you change settings — never resets your progress.
Full-Screen Break Overlay
A separate window that appears over everything when a break is due. Optional Strict Mode prevents skipping.
Eye Health Dashboard
Daily stats, compliance rate, streak tracking, and beautiful weekly bar charts (Recharts). Know your habits at a glance.
Google Auth + Guest Mode
Sign in with Google for cloud sync, or use the app entirely offline as a guest. Row-Level Security keeps your data private.
Silent Auto-Updates
Checks for updates in the background, downloads silently, and shows a live progress toast. Install on quit — just like professional software.
System Tray Integration
Lives quietly in your tray. Closing the window hides it — the timer keeps running. Quit only when you truly want to.
