💤 Android sleep tracking app using real-time heart rate sensors (Polar Verity Sense, Polar OH1+, etc.).
SleepAnalyzerLiteAndroid is an open-source app that collects heart rate data during sleep and visualizes hypnograms, sleep phases, and long-term statistics.
It integrates with BLE sensors from Polar to provide detailed insight into sleep architecture and heart performance overnight.
Live visualization of heart rate stream, sensor status, and circular hypnogram clock.
Displays day-by-day analysis: min/avg/max heart rate and stacked hypnogram durations.
Scroll through previous nights with visual summaries of sleep structure.
Sleep phase timeline + heart rate chart for selected night.
Visual overlays of sleep phase predictions and adjustable quantization parameters.
