Tell ShiftBell your rotation once. It rings on the days you work, at the time you set for that shift. On the days you don't, it stays silent. β Will it handle my pattern? β’ Not on anyone's list? Stack blocks and build the cycle your workplace runs β 2-2-3, DuPont, four on four off, whatever it is. β’ Or pick one already built: β 2 days, 2 nights, 4 off (Continental) β Day, Night, Off β 2 days, 2 evenings, 2 nights, 2 off β 24 on / 48 off β 5-2 (fixed) β’ Handed a new schedule every month? Paint it onto the calendar day by day. β’ Need to change one day? Tap it. β’ Already in your iPhone calendar? Import it (Pro). β’ Set the start date once and the app works out every workday after it. β’ Presets, the cycles you build and per-day edits are all free. β Will it actually wake me? Free rings once, and a check records how you got up: the Confirm button, or a Math problem. Pro is the part that won't take one ring for an answer. Pick Quick Tap, Memory, Typing, Steps, Selfie, Find the open eye or Photo of a place. It comes back every minute until you pass, and turning it off doesn't end it. That is what stops the half-asleep dismissal. On iOS 26 and later, alarms ring through Silent Mode and Focus. β Who it is for Nurses, firefighters and paramedics. Plant swing shifts, 24/48 duty, security, logistics, aviation. Anyone whose schedule is handed to them a month at a time. β Yours, and quiet about it No account, no ads, no tracking. Wake selfies stay encrypted on this iPhone and out of your backups. Log mood and fatigue in seconds when a shift ends. Back the whole thing up to your own iCloud β we still can't read that backup. β Pro Pro adds three things: β’ the seven wake checks that keep coming back β’ your iPhone calendar's events and public holidays, plus shift import β’ custom shift types Everything else is free, including: β’ the commute weather briefing, read out for both ends of your shift β’ mood and fatigue statistics, with a PDF you can share β’ day templates and widgets Yearly starts with a free week.

Verdict
The clearest difference is in-app purchases: TempoFlow at none against ShiftBell's 3. TempoFlow also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). ShiftBell's advantage is ads (none vs shown) and update cadence (every 4 days vs every 11 days). On price there is nothing between them.
