Easy to use
This app is the best way that I have found to to track my heart rate. I dont really care about comparing workouts. I have atrial fibrillation and use it for trending the frequency of my episodes of bradycardia and tachycardia. I use the "custom time period" to create a "workout" of every 24-hour time period and chart my heart rate. I can easily see when my heart rate, tracked by my Apple watch, peaks above 170 when Im not exercising, or when it dips below 50. I summarize these in a spreadsheet to look for patterns and trends. I hope that someone writes an app that addresses a-fib more directly in the future, but until then, this fills the gap!
