I work out every day and would like to just wear the watch, use and app, and get consistent results regarding calorie burn numbers. I do a variety of activities from cardio (Zumba), walking (on hilly terrain which does get my heart rate up quite a bit, e.g. 145 bpm), yoga, and weightlifting. I find that wearing a chest strap (Polar heart rate monitor) combined with iPhone Digifit app gives the most accurate results but I would much rather use my Apple Watch alone and get accurate results. Has anyone had much luck with that? I find that the Apple Watch alone really short changes me for calorie burn, even if I take into account that it deducts my resting calorie burn and only reports the active part. A workout which reached my target in 1.5 hours now is taking 2+. I have tried the native fitness app, Motifit app, with a chest strap and without. Digifit and chest strap is the most generous calorie count, Apple Watch alone with its native app gives the stingiest count. Motifit looks like it misjudges my heart rate a lot (e.g. I know I was at about 145 bpm on a workout but it was showing 113...big difference). I am not looking for scientific accuracy but I am looking for consistency and ballpark estimates without use of the chest strap. Has anything worked for you?
