- Every morning's readHow long you were loud, and when it peaked. In full, every morning.
- The playbackYour own loudest moments, any time.
- The sleep scoreIf you already wear a watch or a ring to sleep, Nagi reads the sleep record it wrote and scores the night out of 100. How long you slept, against the night you ask for, 8 hours unless you set it; when you went to bed, against your own usual, the middle of your last 13 nights; and how long you were awake in the night. The total arrives once 13 nights are in.
- Your whole historyHowever many nights add up, nothing is locked away or cut short.
- The outside air, todayPressure, PM2.5, seasonal pollen. The values themselves, always.

- 01 · Bedtime
One tap
Put the phone by the pillow and start. Tonight's air is on the same screen.
- 02 · Through the night
The recording mark
While it records, the screen keeps saying so. Only the loud stretches are kept; the quiet is never stored.
- 03 · In the night
A dim clock
Wake, and there is only the clock and how long it has recorded. The night goes on untouched.
In a shared bed, Nagi never guesses whose sound it was. The "not me" mark is yours to make, in the morning. There is also a setting for recording the person beside you.
One night, on one page.
The shape of the night's sound and its loudest moment. Every number comes from your own recording.

Example · one night's record At a glance
The loud minutes and the sleep score. Two instruments, one night.
The phone never measures sleep itself. The sleep record an Apple Watch or a ring wrote is read from Apple Health or Health Connect and stands beside the sound. Without a watch or a ring, the whole sound record is still yours.
The screens are examples. The air rows follow the season.
The outside air, beside your nights.
Pressure, PM2.5, seasonal pollen. Side by side, never a verdict on the cause.
The air rows read Japan's own sources for its twelve regions today; you choose your region once, and no location permission is asked. Outside Japan the record is the same, without the air rows for now.

What people ask.
Does it record all night?
The microphone listens all night, but only the loud stretches are kept. The quiet is never stored. Audio is gone after 14 nights; the numbers stay.
Is the recording sent anywhere?
No. The audio never leaves this phone. Only numbers, like minutes, reach the server, and only so the same record opens on another phone.
Does it work in a shared bed?
Yes. Nagi never guesses whose sound it was. The "not me" mark is yours to make in the morning. There is also a setting for recording the person beside you.
Can it tell me whether something is wrong?
No. Nagi makes no diagnosis and no verdict. It measures loud minutes and plays you your own recording. If something worries you, talk to a doctor.
Do I need a watch or a ring?
No. With the phone alone, the whole sound record is free. If an Apple Watch or a ring writes sleep to Apple Health or Health Connect, Nagi reads that too and stands it beside the sound.
Where does the phone go at night?
By the pillow, charging. The screen becomes a dim clock, and the recording mark stays on it the whole night.
How do I cancel?
In the App Store or Google Play, any time, one tap. Cancel within the free days and nothing is charged.
