Alternate focus and rest
Use adjustable work and break timers. Pause, reset, or move to the next interval as your day changes.
Keep everyday lists close
Organize checklists, add notes, reorder items, and pin what matters without turning your routine into a project management exercise.
Make room for your work
Switch to a compact, always-on-top window and choose a light, dark, or system-following appearance.
See your calendar beside your plan
Optionally connect Google Calendar to view events for today and the next 7 days, and add new events to calendars you own. Calendar lists and event snapshots come directly from Google and stay in memory only while the app is running.
Keep your routine local
Schedules, lists, and settings stay on your device, with no accounts, analytics, or tracking. Use JSON export or import to keep a copy of your data.
