Take a 60-second chronotype quiz 2. Connect your Calendar (or enter shifts manually) 3. ShiftRest tells you when to sleep, when to wake, and how rested you'll be BUILT FOR SHIFT WORK - Circadian Rhythm Engine - personalized sleep windows by chronotype, age, gender - Smart Shift Detection - auto-imports rosters from your calendar - Sleep Debt Tracker - see what you owe your body, track recovery - Shift Readiness Score - know if you're rested enough before clocking in - Sleep Sounds - white, pink, brown noise; rain, ocean, forest, fan - Wind-Down Reminders - smart notifications timed to your shift - Home Screen Widgets - next shift + sleep recommendation at a glance - Apple Health sync - sleep data flows seamlessly SHIFTREST PRO Calendar sync, full sound library, advanced widgets, and personalized insights.
