Combat shift work disruption with personalized advice based on the latest circadian science. This groundbreaking app empowers shift workers to optimize their sleep, performance, health, and quality of life with science-based guidance developed by world-renowned circadian scientists. Fast Company: “Congratulations Timeshifter on helping to change the world.” Timeshifter — Shift Work Edition — was developed to help shift workers reduce the underlying problem of circadian and sleep disruption inherent in shift work. With Timeshifter, you will receive highly personalized advice based on your sleep pattern, chronotype, work schedule, and personal preferences. SHIFT WORK MYTHS VS. CIRCADIAN SCIENCE Shift workers face a serious biological challenge: misalignment between their internal circadian rhythms and their work schedules. This circadian disruption leads to insomnia, excessive sleepiness, poor performance, and increased long-term health risks. Popular advice — like drinking more coffee, using supplements, or simply “getting more rest” — misses the mark. These approaches don’t address the root cause: your circadian misalignment. It’s time to replace the myths with real science. Generic tips won’t solve circadian disruption. Only evidence-based interventions that "reset" your circadian rhythms and manage circadian timing can effectively reduce the negative effects of shift work. THE REAL SCIENCE OF SHIFT WORK // In your brain, a circadian clock regulates the rhythm of your day. // Shift work causes your sleep and other behaviors to occur at biologically inappropriate times, resulting in fatigue, poor sleep, and long-term health risks. // Light is the most powerful cue for resetting your circadian clock. The correct timing of light exposure and light avoidance is the foundation of any circadian intervention to improve alertness and sleep quality. If your timing is off, it can make things worse. WHY SHIFT WORKERS LOVE TIMESHIFTER // Based on the latest sleep and circadian science // Optimizes your sleep, alertness, and performance // Reduces the negative effects of shift work on productivity, health, and quality of life Using Timeshifter is as simple as taking small actions at specific times.

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. A COACH FOR NIGHTS, NOT MORNINGS 21 sleep techniques chosen for shift work — fall asleep faster after a late finish, reset on a turnaround, nap without the grogginess. Each one tells you when to use it and how long it takes. PRIVATE BY DESIGN Your data stays on your iPhone. No account. No cloud sync. No employer dashboard. Sleep is read from Apple Health (read-only), and on Pro, explanations are generated by on-device Apple Intelligence — your data is never sent to a server. AUTOMATIC SLEEP IMPORT Last night's sleep from Apple Health appears on its own — open the app in the morning and it's already there. EXPORT FOR YOUR DOCTOR OR OCCUPATIONAL HEALTH Generate a clean PDF or CSV recovery report to share with a GP, sleep clinic, or occupational health team. BUILT FOR • Nurses and rotating hospital staff • Paramedics and firefighters • Factory, logistics, and aviation ground crews • Hospitality and overnight staff • Anyone whose sleep window moves week to week FREE TO START Track your roster, import sleep, see your recovery score, add the widgets, and get shift-timed reminders — free. Upgrade to Premium for multi-calendar background sync, overtime tracking, and on-device AI explanations. One-time Lifetime option available, and Premium is shareable with your family. Available in 39 languages. Sleep isn't broken. The app finally fits the shifts. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
