About Nagi: Sleep & Snore Recorder
Nagi records your own night, exactly as it happened. While you sleep, your phone's microphone quietly listens. In the morning you can hear how long you were loud, when it peaked, and your three loudest moments, in your own ears. No setup beyond one tap before bed, and if you like, Nagi can remind you at your usual bedtime. The sound is sent nowhere. Only the loud stretches are kept. The recording keeps more than snoring. Grinding your teeth, talking in your sleep: anything loud enough is kept the same way. On the free plan, Nagi does not judge what a sound was, and it does not tell snoring from grinding either. It is you, listening back, who decides what a sound was. Mark a moment "probably someone else" or "another sound" and it drops out of the numbers; the recording itself stays. On the paid plan, once your night is recorded, Nagi listens back to the loud parts right on your phone, and the morning shows one more card: of your loud minutes, how many were snoring and how many were something else. Nothing is sent anywhere. Nagi is not only for the person snoring. It is also for the person lying awake next to them. Instead of an argument, there is a record: what actually happened, not just what it felt like at 3am. Nagi asks about you before it shows you a number. Every morning starts with one simple question: how do you feel. If your own sense of the night disagrees with what Nagi recorded, you are right, and the screen says so. There are no targets, no streaks, and a rough night never costs more taps to record than a good one. As your nights add up, your own usual comes into view: not a population average, just your own line. Tag what happened or what you tried (alcohol, a nasal strip, medicine) with one tap, and once your record can carry it, Nagi lays your tagged nights beside the rest in minutes from your own record. The only evidence is your own nights. If you already wear a watch or a ring to sleep, Nagi can stand that night's sleep beside your sound. Nagi does not measure sleep with the phone. It reads the record your own device already wrote to Apple Health. In the morning there is one score out of 100, never against other people and never a goal. Under it stand the three parts it is made of, each with its arithmetic printed: how long you slept, measured against the night you ask for, 8 hours unless you change it under Health in Settings; how close to your usual bedtime, the middle of your own last 13 nights; and waking in the night. Deep, light and REM are drawn in the night's picture and score zero, because we measure them but cannot yet stand behind scoring them, and the screen says exactly that. The total needs 13 of your own nights before it exists; until then the parts show at full value and the app tells you how many nights are left. No watch and no ring means no score, and nothing else changes. The reading and the score are free. Your recordings, playback and your entire history stay free, forever. A paid plan (¥380 a month or ¥3,800 a year, 7 days free, renews until cancelled) exists only for the deeper analysis, never for your own record. Nagi is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Nagi counts; it never claims to find a condition. If snoring, breathing or sleep symptoms concern you, please see a doctor or another medical professional. Typhoon pressure, dry winter air, cedar pollen from February: the season changes, Nagi keeps listening either way. Privacy Policy: https://mynagi.jp/privacy Terms of Use: https://mynagi.jp/terms
What’s new
Version 1.6 · Updated October 14, 2026
Sleep sounds are here: a library of rain, water, fire, fan and noise, nature, travel and sleep music, chosen for your country. Four are free: a rain, a fire, a piece of sleep music and white noise. Set a timer, or start the night with a sound. It plays on while the night records. The morning says how long a sound played, and the ear leaves those minutes out. With the plan, play up to three sounds at once, and Trends puts nights with a sound beside nights without. New sounds arrive without an app update. The sleep page opens on last night, with the night before a swipe away. Text in light mode is easier to read.
