Sleep Tracker: Snore Recorder App
A competent developer can implement core features (recording, snore detection, sleep-stage heuristics, reports, sounds) in a few weeks, but replicating claimed clinical validation, large labeled models, App Store polish, and trust that the paid app sells on requires data, validation, and product effort beyond a single-developer replacement.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Record overnight session, detect snoring/apnea events, infer sleep stages, store night summary, surface reports and play sounds/alarms.
What it still won’t have
- Claims of medical-grade / clinically validated accuracy
- Large labeled sleep and snore dataset used to train models
- App Store reviews, brand trust and existing user base
- Polished UX and cross-device integration (Apple Health / Watch) out of the box
- Ongoing model improvement and clinical monitoring
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a phone-first sleep tracker using React Native (Expo), a small Node.js + Express backend, Postgres, and TensorFlow.js (or a hosted ML inference endpoint). Core features in scope: 1) record and securely store overnight audio segments and accelerometer traces; 2) run a snore-detection model (TFJS on-device or a hosted /v1/infer endpoint) and mark snore/apnea events; 3) infer sleep stages from sensor data and heuristics and store per-night summaries in Postgres; 4) provide daily/weekly summary screens with charts and exportable PDF; 5) implement a sounds library player (catalog management) and a smart alarm that wakes in light sleep. Explicitly out of scope: clinical validation, FDA/regulatory compliance, in-house model training on large labeled datasets, cross-platform app store submission polish. Include error handling for recording failures, permission denials, and network outages; add unit tests for backend endpoints and model integration and end-to-end tests for the main recording-to-report flow.
How we checked
How the score was reached
- Partly verdict base52
- 3/3 assessment runs agreed+4
- Evidence score56
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
