Heart Rate Monitor

Monitor heart rate via BLE devices with real-time display, history, and alerts

New in version 4.8

- BLE optimization: use Kable's onServicesDiscovered callback to call requestMtu, negotiating a larger MTU (517) after connection — reduces heart rate data fragmentation and improves transfer reliability; automatically falls back to the default on negotiation failure without affecting the connection
- BLE optimization: call Kable's AndroidPeripheral.requestConnectionPriority once connected to request high connection priority (minimum connection interval), lowering heart rate notification latency

A lightweight heart rate monitoring app for Android, built with Jetpack Compose and Material 3. Connect to BLE heart rate monitors and track your heart rate in real time.

Features:

- Bluetooth LE heart rate monitoring: scan and connect to any BLE heart rate device
- Real-time heart rate display with animated heart icon
- Floating window overlay for always-on heart rate display
- Status bar heart rate indicator with auto color adaptation
- Heart rate history with chart analysis (powered by Vico)
- Heart rate alerts with posture detection (sitting/standing/exercising)
- HTTP server and WebSocket server for real-time data streaming
- Webhook support for pushing heart rate data to external services
- Favorite devices with auto-connect
- Fully customizable UI: colors, opacity, corner radius, size
- Material 3 design with dynamic color support (Android 12+)
- Fair memory management for Chinese OEM devices (vivo, Xiaomi, OPPO, Honor)
- Privacy-friendly: no tracking, no ads, no analytics
