Heart Analyzer is one of my favorite Watch apps. Chance Miller has details on why its so good and getting better.
With support for live heart rates, Heart Analyzer will now record your heart rate in real-time when you have the app open. This allows you to get detailed information about your heart rate at specific times, and view trends and graphs over time.
Wait. There’s more!
Heart Analyzer… also now displays your recent workouts. Here, you can see a detailed heart rate graph with minimum, maximum, and average data points.
Impressive. Remember, performance measured is performance improved. That explains why health insurance companies want their customers to use Apple Watch.
