Data from wife's exercise today, Indoor cycling (spinning). Digifit app and Apple Watch started simultaneously prior to exercise activity. Apple Watch set to "Indoor Cycle" Digifit Results: Exercise Time: 1:06:05 BPM Avg: 147 BPM Max: 162 Calories: 670 Apple Watch Results: Total Calories (8:00 am to 6:30 pm): 378 (no way, she had 670 during the 1:06:05 of exercise) Exercise Time: 43 minutes Exercise Calories: 239 Dashboard Min Heart Rate: 41 BPM (not likely) Dashboard Max Heart Rate: 234 BPM (not likely) 1. Why does the Apple Watch register 23 minutes less exercise? 2. Why does the Apple Watch register 431 less calories for the exercise activity? 3. Need a readout that shows BPM Avg and BPM Max for exercise period. 4. Why doesn't Apple acknowledge there is an issue with the Activity / Exercise app and at least say they are addressing the issue? All this despite carrying her iPhone, despite wearing the watch tightly, despite choosing the correct workout type, despite wearing the watch regularly.
