I was looking at Superset, the Health app and Athlytic this morning. Both the health app and Athlytic had my resting heart rate the same. Superset has it almost 10 points higher. Do you know when you are taking the reading of resting heart rate to report? I know Garmin take the reading in the last few minutes of sleep, which makes the heart rate seem lower than it really is. I don't like Apple's average of the day either. If you have a tough workout (long run), it will use the higher readings later in the day. I think the lowest in the first hour of waking up seems to be the best (just my thought). Thanks for an amazing app, it looks amazing
