A Chrome extension that blocks distracting websites during focus sessions.
- 25/5 Pomodoro timer with long break (15 min) after every 4 sessions
- Site blocking — blacklist sites that redirect to a focus page during work
- Whitelist exceptions — e.g. block
youtube.combut allowmusic.youtube.com - Allow-only mode — block everything except a chosen set of sites
- Presets — saved profiles (e.g. "Manga") that set the block mode, site list, apps to close, and an optional URL to auto-open when you press Focus
- App blocking (macOS) — quits chosen apps during focus via a native helper
(see
native-host/) - Strict mode — requires 10 clicks + a written reason to stop a session early
- Task label — set what you're working on, shown on the blocked page
- Ambient sounds — rain, white noise, or brown noise while you work
- Break suggestions — quick exercises (push-ups, squats, etc.) during breaks
- Weekly heatmap — GitHub-style grid of your daily focus minutes
- Configurable durations, auto-start, session stats
