The Apple Watch is great at many things, but it is not the best at measuring your heart rate. It's not always reading, and when it does, it drains the battery, and still it can be inaccurate. There's nothing like a dedicated heart rate strap and the folks at Wahoo have developed one that is quite smart. The TICKR X ($99.99) is an app-enabled Bluetooth-based heart rate chest strap that could even lower your blood pressure simply because you don't have to worry about battery life! The included coin-size battery lasts 12 months.
