I have been getting into fitness of late. While my body is getting better, my brain hurts. I wish I could get a consistent quantification of health data. I use a combination of the stock Health, My Fitness Pal, Blind Square, and Zombies Run. I use either a treadmill, or the great outdoors. I will use today's walk for an example of my issues. Let's check the distance. Blind Square said I walked 5.1 miles. Zombies Run, using a set stride length step count said 5.01 The Health app dashboard said 5.67 miles. I cannot find a way to determine how the Health app turns steps into distance. It doesn't appear to have a setting for stride, and doesn't seem to ask for GPS access. How about calories? My Fitness Pal claims I burned 917 calories. Zombies Run said I burned 240. The Health app has a function for calories, but it is blank. What matters most is that I'm eating less, and moving more. The numbers aren't that important. But it drives me crazy that the apps all come up with different stuff. I want one number I can hang my hat on, and work with.
