ShiftRest vs ShiftRhythm

Sleep Cycle gives you a red score every time you sleep at 10 AM. ShiftRest is the only sleep planner for shift workers that doesn't punish you for sleeping at noon. Built for 22 million nurses, firefighters, and EMS who don't work 9-to-5. WHY SHIFTREST IS DIFFERENT - It's a planner, not a tracker. We don't score your sleep. We tell you when to sleep. - Schedule-first. Type your rotation. Get a sleep window tuned to your shift, not a generic 10pm-6am bedtime. - No red scores for daytime sleep. No "you missed your goal" notifications at 3 AM. No moralizing. - Built on circadian science: AASM clinical guidelines, CDC NIOSH shift-work data, NASA chronotype research, Phase Response Curve algorithms. WHAT YOU GET - Personalized sleep window — tuned to your specific rotation (3x12, 24/48, continental, custom). The window moves with you. - Melatonin timing by chronotype — not a generic "take 3mg at 9pm." The PRC algorithm calculates your circadian phase shift and tells you the exact window. - Caffeine cutoff by sensitivity — slow metabolizers get 8 hours, fast metabolizers get 4. We ask, we adapt. - Transition plans for rotating shifts — multi-day plans for night-to-day and day-to-night flips. When to nap. When to expose to morning light. When to skip melatonin. The killer feature competitors don't have. - Light and dark protocol — when to wear blue-blockers, when to seek bright light, when to nap before a night shift. - Always-free baseline — schedule input, basic sleep window, generic caffeine cutoff. Never paywalled. WHO IT'S FOR - ICU and ER nurses on 3x12 night rotations. - Firefighters and EMS on 24/48 or 48/96 schedules. - Factory workers on continental 2-2-4 patterns. - Pilots, oil-rig crews, doctors on call, anyone whose body is asked to do something the sun didn't agree to. NOT FOR - 9-to-5 office workers (try Sleep Cycle, RISE, or Pillow). - People looking for a sleep tracker score. - Anyone who wants their app to scold them at 7 AM. THE SCIENCE ShiftRest is built on AASM (American Academy of Sleep Medicine) clinical guidelines for shift work disorder, CDC NIOSH research on rotating shifts, and Phase Response Curve algorithms used by NASA for crew chronobiology. We don't make medical claims — we apply established circadian science to your real schedule. PRICING - Free forever: schedule input, basic sleep window, generic caffeine cutoff. - 7-day free trial of Premium, then: - Monthly $5.99 - Annual $49.99 (save 35%) - Cancel anytime in your Apple ID settings.

If you suspect shift-work sleep disorder, insomnia, or sleep apnea, consult a board-certified sleep physician. If you are in crisis, contact 988 (US), 116 123 (UK), or 13 11 14 (AU). PRIVACY Your schedule and sleep data stay on your device or in your encrypted account. We do not sell data. HealthKit integration is opt-in. — — You've worked the night shift for 12 years. You know your body. You don't need another app to tell you sleep is important. You need an app that respects that you sleep at noon — and helps you do it well. Rest catches up, gently.
