AfterShift vs ShiftRhythm

Most sleep apps assume you sleep at night. If you work shifts, that's the whole problem — they score you against a 9-to-5 clock you don't work, so the nap you took before a night shift looks like "failure" instead of recovery. AfterShift is built the other way around. It measures your sleep and recovery between shifts — shift-to-shift, not midnight-to-midnight — so the numbers finally match the life you actually live. GLANCEABLE — WITHOUT OPENING THE APP Your next shift lives on your Lock Screen and Home Screen. Widgets show the countdown to your shift, your recovery, and your plan for right now. A Live Activity counts you down to shift start — then rolls into your wind-down window — on the Lock Screen and in the Dynamic Island. Start an anchor nap and watch it tick down there too. All free. YOUR ROSTER, READ FOR YOU Connect your calendar and AfterShift detects your shifts automatically — no typing in three weeks of rota by hand. It even spots overtime and schedule changes. Five shift types are modelled: day, evening, night, on-call, and off. RECOVERY, TIMED TO WHEN YOU CLOCK OUT See how ready you are for your next shift, how your sleep debt is trending across cycles, and a clear recovery plan for the hours you actually have — not a generic "aim for 8 hours" you can't reach before a 7pm start. YES, THE NAP COUNTS Pre-shift naps, split sleep, and on-call rest are first-class here. AfterShift knows a 90-minute nap before nights is recovery, and scores it like one. REMINDERS TIMED TO YOUR SHIFT — FREE Wind-down, caffeine cut-off, and nap-window reminders fire relative to your next shift start, not the clock on the wall. All free.
