Japytu — Sleep Monitor

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.
