I keep my phone on fitbit app while exercising to kerp track of calories without having to look at my tracker. I noticed a drop in my calories after exercisinf approx 30 minutes and notuced my calorie count showed almost no calories burned. Tried to sync but couldn't. Restarted device and no change. While syill exercising, I watched it jump by over 100 calories then a few minutes later dropped by almost 100. Then it jumped back up till I was over by about 100 calories. When I went to bed I checked my calories and it had dropped again. I know I hit my goal because I exercised longer than usual because of the fluctuations. What is going on????
