## What is HeartCast?

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
