HNSleep

Yishui is an offline-first night recorder: one tap before bed, one thing worth knowing in the morning. No account, no subscription, and your nights never leave the phone. [PHONE NIGHT RECORDS] Place the phone by the bed and tap once. Yishui computes volume and timing on device, building a sound-clue timeline; full-night audio is never saved or uploaded. End in the morning for a brief report: time in bed, sound clues, and one suggestion you can act on tonight. Mark false positives and the statistics update instantly. [APPLE HEALTH · WATCH SLEEP] Only when you ask, Yishui reads Apple Health sleep samples: with Apple Watch data it shows "watch-estimated sleep" side by side with your phone's in-bed record, never blended. Verified purchasers can open sleep-stage details and a 30/90-day health comparison; health samples stay in memory only. [LONG-TERM REVIEW] The last 7 nights are free. 30/90-day trends, complete/partial/sound filters and on-device CSV export are part of the lifetime unlock; missing nights stay blank. [WIND DOWN] A two-minute breathing exercise and three text-guided practices (2/3/4 minutes). One is free; two come with the unlock. Fully offline. [APPLE WATCH] The watch shows monitoring status, a two-minute breath and the morning line; verified purchasers can review a 30/90-day phone summary. Without a watch, Yishui works in full. [ONE-TIME UNLOCK] "Yishui Complete Unlock" is a single non-consumable purchase: richer reports, 30/90-day trends and export, sleep stages, optional short sound clips with playback, all 8 warm themes and every text practice. No auto-renewal, no ads. [PRIVACY] Raw audio is off by default; optional short clips (≤10 s each) require your per-night opt-in, use system file protection, are excluded from backups, retained for 7 days and deletable anytime. No tracking, no ad SDK. App Lock uses system Face ID/passcode. One step deletes local records without touching Apple Health. Sound clues are volume-activity events; they cannot confirm snoring or any condition. Yishui is not a medical device; if you wake gasping or feel very sleepy in the day, talk to a doctor.
