LunaRest turns your phone into a complete sleep monitor — no wearable, no account, and all sleep analysis happens right on your device.
UNDERSTAND YOUR NIGHTS
Sleep stages (awake, REM, light, deep) with a full hypnogram
A sleep score with a fully transparent breakdown — see exactly why you scored what you scored
Movement, room-noise and breathing-rate graphs
Duration, efficiency, time to fall asleep and awakenings
HEAR WHAT YOU CAN'T
Detects snoring, sleep talking, coughing, sneezing and baby cries — each can be switched off individually
Optional short audio clips of detected events, stored only on your phone and auto-deleted after a period you choose
See how long you snored each night
WAKE UP GENTLY
Smart alarm wakes you during light sleep near your chosen time
Guaranteed wake-up: if no light-sleep moment is found, it still rings at your target time
Volume ramp, vibration and snooze
FALL ASLEEP FASTER
14 soundscapes — rain, thunderstorm, ocean, forest stream, campfire, crickets, brown noise and more — generated on your phone, nothing to download or stream
Mix up to three sounds together, each with its own volume
Fade-out sleep timer and a bedtime reminder
SEE THE BIGGER PICTURE
7 and 30-day trends: duration, score, stages and bedtime consistency
Sleep debt against your personal goal
Journal tags (caffeine, alcohol, exercise…) with automatic pattern insights
Nap mode keeps daytime naps out of your nightly stats
Works for night owls, early birds and shift workers alike
YOUR DATA STAYS YOURS
Sleep data, audio and reports never leave your phone — no cloud, no sleep-data sharing
Export everything as CSV or JSON, or delete it all with one tap
Gentle mode swaps numbers for words if scores make you anxious
Free, supported by ads. Ads never access your microphone or your sleep data.
HOW IT WORKS
Place your phone on the mattress, tap Start sleep, and LunaRest senses sound and movement through the night — with a visible notification the entire time. In the morning, your full report is waiting.
LunaRest is not a medical device. Sleep stages and breathing rates are estimates from phone sensors, meant for spotting patterns. If you suspect a sleep disorder such as sleep apnea, please talk to a clinician.
