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.
