Rest Window: Sleep Timing

Rest Window — sleep timing for real schedules. If your work schedule doesn't look like 9-to-5, neither should your sleep app. Rest Window is built for the people whose lives run around the clock: nurses, doctors, EMTs, firefighters, dispatchers, pilots, transit operators, on-call engineers, new parents, students cramming for exams, and travelers crossing time zones. Five focused calculators help you plan sleep around the day you actually have. SHIFT WORKER For rotating, night, and on-call schedules. Enter your shift start time and Rest Window walks you backward — when to wind down, when to climb in bed, when you'll actually fall asleep, and when to wake. Built for the realities of swing shifts and split sleep. NAP PLANNER Power naps (20 min), full-cycle naps (90 min), or recovery naps (3 hr) — choose by sleep mode or by the time you need to be ready. For nurses between shifts, parents catching minutes when the baby's down, and students pacing study breaks. SLEEP CYCLES The classic question: "If I go to bed now, when should I wake up?" Rest Window calculates wake times at full 90-minute cycle boundaries, so you're rising between cycles instead of mid-deep-sleep. Includes fall-asleep buffer and wake buffer adjustments. JET LAG PLANNER Crossing time zones for work or family? Plan your sleep schedule in advance with eastbound and westbound adjustments. Reduce the wreckage of long-haul flights and irregular international travel. NO ALARM MODE For the rare day you don't need to be anywhere — a weekend, PTO, or a recovery day after a brutal stretch. Pick your sleep start time and see when you'd naturally wake at each cycle boundary. Wake at a biological boundary, not a buzzer.
