Home sleep apnea monitoring, developed as independent research

Why

Sleep apnea is common and often goes unrecognised for years. A sleep laboratory study is precise but expensive and hard to get, and home sleep tests are borrowed for one night at a time. The project explores whether affordable wearable sensors and a phone can record many nights at home with enough quality to show when a proper examination is worth it, and how a treatment works over time.

The app

The Android app Apnoe záznam (Apnea recorder) records the night from wearable sensors connected over Bluetooth.

• Night recording. A checklist before sleep shows only what still needs to be done; the app then confirms that the sensors are worn properly and records with the screen off.
• Marks during the night. One tap notes waking up, going to the toilet or putting a CPAP mask on and off.
• Morning summary. A few seconds after the recording ends the phone evaluates the night: recording quality, battery use, walking at night and, in the test version, research estimates of breathing events and blood oxygen drops. Every value has an explanation.
• Built-in help. A manual, an app tour and explanations right on the screen.

Privacy

Recordings stay on the phone. Nothing is evaluated in the cloud and nothing is sent during the night. Data leave the phone only when the user sends them: sharing a recording, a bug report after a preview of everything it contains, an optional question to the AI help with the user's own key, or a technical crash report the user allowed. There is no account and no advertising.

Status

The app is a test version used by the developer. The detection is being validated against manually scored reference recordings before any wider use. If the proof of concept succeeds, the goal is to develop it into a certified, affordable home screening device. Until then the results are research estimates only; a doctor decides about any examination or treatment.
