LUMO: Sleep Tracker & Snoring

LUMO is a contactless sleep tracker that uses only your phone on the nightstand. Nothing to wear, nothing in your bed, no account. Everything is processed on your phone.

LUMO is a wellness app, not a medical device. It does not diagnose, treat, cure, or prevent any medical condition.

HOW IT WORKS
• Your phone's speaker plays a tone too high to hear
• The microphone senses how it reflects as your chest rises and falls
• LUMO turns breathing and movement into sleep stages and a sleep score

SLEEP TRACKING WITHOUT A WEARABLE
• Sleep stages: light, deep and REM, shown as a clear hypnogram
• A 0–100 sleep score that sums up your night
• Breathing rate and restlessness through the night
• Works all night with the screen off

SNORE RECORDER & SLEEP SOUNDS
• On-device AI recognizes snoring, coughing, sleep talking and other night sounds
• Listen back to short clips in the morning and hear what happened
• Teach LUMO new sounds, like a fan or a partner snoring
• Clips stay on your phone and you can delete them anytime

MORNING SUMMARY
Wake up to a calm summary of your night: your score, your sleep cycles and a plain-language read on how you slept. No jargon, no guilt.

WIND DOWN & FALL ASLEEP
• Guided breathing exercises and a short wind-down routine
• White, pink, brown and green noise with a sleep timer

WEARABLE DATA (OPTIONAL)
Have a ring or watch? Connect it through Health Connect to see heart rate and HRV next to your sleep stages. Off by default.

PRIVATE BY DESIGN
• No account, no cloud, no ads
• Your nights never leave your phone
• Export or delete your data anytime

FREE & PREMIUM
Tracking, the morning summary, breathing and wind-down are free. Your first 7 tracked nights include Premium, with saved history, trends and full sound analysis.

BEST RESULTS
Place your phone on the nightstand at bed height, plugged in. Tap Begin and sleep as usual. LUMO checks the first time that your phone's speaker and microphone can produce the sonar tone.
