It supports Bluetooth and ANT+ connectivity, allowing you to pair with multiple devices at once, which is great if you want to use it with fitness equipment or apps on your iPhone.

The H10 is fully waterproof, so you can wear it while swimming or in heavy sweat without worry. It also includes internal memory, meaning you can record data without needing your phone nearby. The device uses a lithium battery which typically lasts many hours before needing replacement. It is a chest strap, not a wrist-based monitor like the Apple Watch itself, so it might feel less convenient if you prefer wristwear.
