You should put some axes on the steps/calories burned graphs. The upper left time looks like the updated time, but is the graph time over the past hour, day?
Each individual data point is total steps and or calories for a singular day. The count in the top right is for today (and it's always the last data point on the graph). Then it goes today-1, today-2, etc..
Thanks for taking the time to check it out and providing some feedback, I do appreciate it :)
