Turn better sleep into a calm game. Track your nights, understand your score, follow one gentle plan, and grow a moonlit grove—privately, at your pace.
Let’s Sleep turns better rest into a calm, rewarding experience. Track your nights, understand your sleep patterns, follow one gentle plan each evening, and grow a peaceful moonlit grove along the way.
SLEEP TRACKING THAT WORKS FOR YOU
• Log your sleep manually using only your iPhone
• Automatically import sleep data from Apple Health
• Use compatible trackers for additional sleep-stage details
• Add Apple Watch recovery metrics, including HRV, resting heart rate, respiratory rate, wrist temperature, and daylight exposure
Apple Watch is optional—Let’s Sleep is fully usable without one.
UNDERSTAND YOUR SLEEP SCORE
See what helped your score, what held it back, and how much data was available. Recommended sleep ranges are based on published NSF and AASM consensus guidance, with sources provided inside the app.
REMEMBER EVERY NIGHT
Browse your sleep history in a simple calendar, review trends, and add personal context such as stress, travel, caffeine, alcohol, exercise, illness, or custom tags. Add notes to remember what made each night different.
Let’s Sleep presents patterns as helpful associations—not judgments or medical conclusions.
A GENTLE DAILY ROUTINE
Receive one calm, practical suggestion through Tonight Plan. Optional bedtime reminders, morning check-ins, and wind-down activities help you build a healthier rhythm without pressure.
GROW YOUR GROVE
Restful and consistent nights help your tree grow. Over time, your progress becomes a peaceful grove filled with memories. Difficult nights never destroy your progress—they simply give you space to begin again.
