I have integrated HealthMate with MyFitnessPal but there are a few of issues. Not sure if these are bugs or if it is working as designed.
1. The data is syncing correctly for previous days, but the current day always shows Consumed is 0. I have verified that the data is up-to-date on the MyFitnessPal website.
2. The target calories for the day don't match. I have selected a weight loss goal of 1.5 lbs/week in both apps. MyfitnessPal suggests a Goal of 1,750 kcal/day, while HealthMate shows Initial as 1,500 kcal/day
3. The Exercise calories don't match between MyFitnessPal and HealthMate. Interestingly the sum of Goal/Exercise in MyFitnessPal and Initial/Exercise in HealthMate is pretty close.
