What Is ShiftSleep?
ShiftSleep is a sleep planning and tracking app built for shift workers. It takes your actual shifts and builds a daily plan: when to sleep, when to cut caffeine, when to seek bright light. It also tracks your sleep clinically, measures your sleep health scores, and generates reports you can share with a doctor.
Daily Sleep Plan
A new plan is built every day based on your upcoming shifts and personal profile. Each plan includes:
- • Sleep window — when to aim to sleep and wake
- • Caffeine cutoff — when caffeine is likely to interfere with your next sleep block
- • Light guidance — when to seek bright light and when to avoid it
- • Melatonin timing — shown only when it may help; suppressed for pregnancy, postpartum, health or medication factors
- • Pre-shift nap window — whether a short nap before your shift is worth taking
- • Confidence level — how certain the plan is given your schedule context
- • Advisory notes — plain-language explanation when the plan is more conservative
Sleep Diary
Clinical-grade per-night logging. Each entry captures:
- • Bedtime and lights-off time
- • Sleep Onset Latency (SOL)
- • Number of awakenings
- • WASO (minutes awake after falling asleep)
- • Wake time and out-of-bed time
- • Sleep efficiency percentage
- • Nap count and duration
- • Quality and sleepiness ratings (1–5)
- • Influencing factors
- • Free-text notes
