Hear what your night
has to say.
Moonsoon listens while you sleep and turns your night into a calm morning report — your snoring, the words of your sleep talk, coughs and more, all worked out on your iPhone. Nothing is uploaded.
Free to start · Your first night fully unlocked · iPhone
Your night, in plain words
Start Sleep, put your phone by the bed, and wake up to what actually happened.
What you said
Read the words of your sleep talk, turned into text by Apple's on-device speech recognition. Moonsoon never sends your voice or its words anywhere.
Snore experiments
Try one change for 7 nights — side sleeping, a nasal strip, no alcohol in the evening — and see in plain numbers whether your snoring changed.
Wake gently
Your alarm can ring up to 30 minutes early when Moonsoon hears you stir. On iOS 26 a system alarm backs it up, even if the app was closed.
Apple Watch vitals
Wear your Watch to bed and your report shows its sleep stages and overnight vitals — blood oxygen, respiratory rate, heart rate and breathing disturbances — read from Apple Health if you allow it. Free for everyone.
A summary for your doctor
Thirty nights on one PDF: snoring per hour in bed, loudness, sleep talk, coughs and breathing pauses (beta), with your Watch's vitals only if you leave them in. You share it yourself.
What the PDF shows →Private by design
Recording and recognition happen on your iPhone. No account, and Moonsoon never uploads your recordings.
- Snoring, sleep talk and coughs, recognised through the night, with a snore score and how each night compares with your recent ones
- Sleep sounds — rain, ocean, white, pink and brown noise and more — with a fall-asleep timer that fades out
- Keep the clips that matter past the 7-night auto-delete, and share a snore with your doctor or dentist
- Start a night from a widget, Control Center, the Action Button or Siri — and ask Siri “How did I sleep?”
- Delete any night or recording, any time — or everything at once
- In English, Spanish, German, French, Portuguese, Italian, Polish, Dutch, Korean and Japanese
Moonsoon is not a medical device and does not diagnose sleep disorders. If you snore loudly and wake up gasping, or feel very sleepy during the day, talk to a doctor.
Hear everything before you decide
- Your first night is fully unlocked — every clip it caught. After that, the free plan unlocks the 5 most significant clips of every night, plus basic trends and your Apple Watch's data.
- A short ad is always optional. Watch one only when you want something more — another clip, a Premium sound for the night or detailed trends until tomorrow. Premium has no ads.
- No surprise charges. If you start with an introductory offer, Moonsoon reminds you before the full price begins, and you can cancel from inside the app.
Moonsoon never uploads your audio
Every recording is captured and recognised on your device and kept in the app's local storage for your last 7 nights, then deleted automatically — unless you choose to keep a clip; a kept clip is also part of your device's own backup, so a device restored from it still plays it. Delete any night or recording, any time. Moonsoon has no login and never uploads your night sounds. Read the full Privacy Policy.
