Japytu — Sleep Monitor
Sleep insights, made simple
Only for iPhone

Sleep. Japytu listens.
Japytu turns your iPhone into a complete sleep monitor using only the
microphone. Leave it on your bedside table, tap “Start sleep,” and rest. In the
morning, see what happened throughout the night.
WHY JAPYTU IS DIFFERENT
• Built for split sleep: Japytu evaluates your rest across all 24 HOURS. Your
night, morning nap, and afternoon nap contribute to one score that updates as
the day unfolds. Traditional apps assume you sleep once a day; Japytu does not.
• Privacy by design: no account, proprietary cloud, ads, or analytics. Japytu
does not transmit your data because there is no server to send it to.
• Complete transparency: the app shows what it hears in real time and why each
sound was or was not recorded. It also includes a report of everything the
classifier noticed during the night.
• Automatic room calibration: the app learns the background noise and measures
sounds relative to it, whether your room is silent or has a fan running.
• Unusual sounds identified by name: a dog barking at 3 a.m., an alarm, or a
knock — Japytu recognizes the sound, records a clip, and tells you what it was.
FEATURES
• Intelligent detection of snoring, breathing that may be snoring, speech,
coughing, movement, alarms, animals, and weather or street sounds, with short
audio clips you can review
• Nighttime activity pattern based on sounds in the room
• Night score combining automatic sound analysis and your morning assessment
• Designed for polyphasic sleep: naps contribute to your total daily rest
• Room noise statistics including baseline, average, and peaks
• Progress charts from 7 to 90 days, a 24-hour sleep map, and trends
• Optional Apple Health integration that writes only the times of confirmed
nights and naps — never audio, notes, or estimated sleep stages
• Live Activity on the Lock Screen and Dynamic Island
• Resilient to calls and interruptions, with recovery if a night is interrupted
TOTAL PRIVACY
Japytu does not send data to our servers. There is no account, proprietary
cloud, advertising, or analytics. Sound recognition happens on your device and
audio clips are excluded from device backups. With your permission, the
optional Health integration writes only the sleep times you confirm.
Japytu is not a medical device and does not replace professional evaluation.

Nighttime recording now works more reliably when the screen is locked. We’ve also improved background maintenance to properly clean up audio files according to your retention settings.
