Tembri is a shift calendar for people who work rotating shifts. You do not need to sign in first. Day shifts, night shifts, days off, and one-off items stay on this phone. The week view is for the next few days. The month view is for the rhythm of the whole month. Open a day, pick a usual shift, and it goes straight onto the calendar. Statistics tells you how many times you worked each shift this month, then adds days worked, days off, and estimated hours. The figures come from the roster on this phone, so you can look back and check them without a wall of numbers. When you have a paper or photo roster, you can photograph it and import it. Tembri asks you to confirm your name, then shows the recognized result day by day. Confirm the name, check each day, and only then decide whether to import, so someone else's shifts do not land on your calendar. You can set local reminders for the shifts you planned. If your unit has already configured and published a schedule outside the app, sign in to view that unit schedule, in-app messages, and tasks, and sync a task into your personal schedule. Main features: - Week and month scheduling on this phone - Quick Add for usual shifts - Shift counts, days worked, days off, and estimated hours - Scan a roster, confirm your name, and review each day before import - Local reminders and Excel workload export - After sign-in, view unit-published schedules, in-app messages, and tasks
