SimpleShift is a simple shift calendar for people who work shifts. Plan your rota, see what’s coming up at a glance, and stay on top of your hours without the clutter of a full planner app. Your schedule lives on a clear month or week calendar. Add shifts quickly, jot notes for individual days, and share a snapshot of any month when you need to. Create shift templates with your times, colours, and labels, then swipe them onto the calendar for fast scheduling. For rotating rosters, build a repeating pattern once and apply it in seconds instead of filling in every day by hand. Track hours and pay with hourly rates, monthly and annual summaries, and charts. Export pay data when you need it. Home Screen widgets and Apple Watch keep upcoming shifts visible at a glance, and optional reminders notify you before work starts. Choose colours and themes that fit you. Optional iCloud sync backs up your calendar across your devices. SimpleShift keeps your data on your device and in your iCloud, private by design, with no account required.
