On rotating shifts your routine and your real schedule never match. Hachiko fixes that with alarms that actually sound and actions that take seconds.

The Slip Every Shift Worker Knows

Rotating shifts have a trap: your daily habit and your real hours don't line up. The brain's autopilot ('I always start at 8') is exactly what trips you up. A shift calendar is useless if it doesn't warn you at the right moment.

One Alarm per Shift, High Priority

In Hachiko every shift can carry its own alarm, linked automatically when you paint your month — no creating reminders one by one. The alarms use a high-priority system so they stand out among other notifications. 'I lost track of time' stops happening.

Paint Your Month in One Tap

Create your own shift types with colours and abbreviations (M, A, N, off) and paint the days with a single tap. A whole week of the same shift? Done in seconds. Forget the paper calendar full of crossings-out.

Notes, Day Photo and Widget

Add notes and icons to any day, and attach a photo — perfect for a signed work report, a receipt or the paper rota. The home-screen widget shows today's shift without opening the app. And with multiple profiles you can manage two jobs at once.
