## What is Zzzentinel?

Zzzentinel watches over your nights. Start the night watch, put the phone by your bed, and while you sleep it listens and understands: snoring graded mild, moderate or loud, sleep talking with on-demand transcription, coughing, your breathing rhythm, and sounds it cannot name — honestly labeled as undefined and ready for you to teach it what they were.

In the morning you get a human report in the tone you choose: what happened, when, how loud, with short clips you can play continuously and scrub with a finger. And when the app is not sure — a sound it heard for the first time, or a guess from your own trained model — it asks. One tap confirms it, one tap corrects it, and every answer makes the next night smarter.

• All-night recording and analysis on device, 300+ recognized sound classes
• Snoring intensity grading and episode grouping
• Sleep talking transcription (on device where available)
• Breathing rhythm overview with an optional, clearly experimental note on longer pauses — Zzzentinel is not a medical device
• Teach it your own sounds: train a personal Core ML model on the phone, listen to every sample, rename or prune your definitions
• A confirmation queue that asks only about what it is unsure of
• Three report styles — playful, neutral, clinical — that vary night to night
• Export nights as audio, transcript, or a single ZIP with a data table
• Guard Extra Plus: arm the phone as a bedside guard — movement or a loud sound triggers a siren until your PIN is entered; arm it from Apple Watch, Siri or a Back Tap
• Watch complication to reach the guard from your wrist
• Slovak and English; no accounts, no ads, no analytics

Privacy first: everything is recorded, analyzed and stored only on your device. Nothing is ever uploaded.


## Version history (last 5 releases)

### 2.6 — 2026-09-24

More honest breathing, smoother handling:
- Breathing analysis now works on stretches of audible breathing and the quiet between them - more accurate pause detection and no false pauses for intermittent snorers
- The clinician summary no longer states an interval between breaths (a microphone cannot measure it); it reports stretches of audible breathing and the quiet between them
- Listen to a breathing pause directly in Episodes, not only in Events
- Your own sound names ("rustling sheets", "creaking bed") stay yours - no longer mistaken for crying or teeth grinding
- A personal "Snoring" sound and built-in snoring no longer split one stretch into hundreds of files
- Exports (ZIP, transcript) are safe while a night is still recording
- Recording recovers on its own if the system quietly stops it
- Small fixes: progress for clinician and merged exports, storage total refreshes, PIN mismatch message, accessibility

### 2.5 — 2026-09-13

More accurate breathing, smoother recordings:
• Breathing rhythm and pauses are now measured from individual breath cycles, not whole recordings — more accurate, more reliable pause detection
• Listen to a breathing pause directly (the breaths before it, the silence, the breath after)
• New "Clinician summary" export — a plainly-worded, professionally-termed night overview (PDF) with recordings of the longest pauses, ready to bring to a consultation
• One sound, one recording — snoring stretches, sentences with pauses and other continuous sounds are no longer split into many files
• Older nights: share an episode as a single merged recording
• Fewer, better "To confirm" prompts — suggestions never turn into facts on their own
• Your own sound names are kept exactly as you typed them
• Training keeps your sounds out of the "other" class, so the personal model learns cleanly
• Stability fixes for audio interruptions and data export

### 2.4 — 2026-09-11

Zzzentinel now learns from you:
• "To confirm": the app asks about sounds it heard for the first time or isn't sure about — confirm or correct with one tap
• Edit your definitions: rename a sound, listen to every training sample, remove the ones that don't belong
• Name any recorded sound, not just undefined ones
• Smarter breathing analysis: ignores moments you were awake, compares against your local rhythm, stays quiet when there isn't enough data
• More sensitive detection — quieter, shorter sounds no longer slip through
• Morning reports are more consistent and vary their wording
• Every export now includes a data table of what was measured

### 2.2 — 2026-09-07

EN: A faster, nicer night: • Quicker app launch — even with hundreds of recorded nights • Instant night deletion, smoother playback and scrolling • Subtle haptics: PIN keys, guard-armed confirmation, recording start/stop — on Apple Watch too • Guard: the alarm always lights up fully, first arming continues right after PIN setup, more reliable arming from the watch • Morning reports now vary their wording in all three styles, with a new tone for calmer nights • Settings shows how much space your nights take • Many small stability fixes

### 2.1 — 2026-09-05
