Description
BeatCast is a pure software solution that broadcasts real-time heart rate from your Apple Watch to cycling computers via Bluetooth Low Energy (BLE) — no chest strap needed.
Key Features:
Direct Mode: Apple Watch broadcasts BLE heart rate signal directly. Search for "heart-watch" on your bike computer to connect.
Bridge Mode: Watch sends heart rate to iPhone, which broadcasts BLE signal (device name "heart-phone") for broader bike computer compatibility.
Real-time Sync: Watch and iPhone stay in sync via WatchConnectivity.
5 Heart Rate Zones: Based on the Karvonen HRR formula, with customizable age and resting HR.
Dynamic Island & Lock Screen: Live heart rate, zone name, and connection status at a glance.
Privacy First: All data processed locally on device. No data uploaded to any server. Fully compliant with privacy regulations.
Perfect for:
Monitoring heart rate on your bike computer while cycling
Replacing a traditional chest strap with just your Apple Watch
Tracking heart rate zones during indoor training
