I am using 5S. It has M7 co-processor which tracks all the steps walked and displays them on health app's dashboard. I can see today's steps. But I cannot figure out how many total steps I took yesterday or any day before. There is an option "Show all Data" and all previous days data is there but that's incredibly useless. How to see aggregate no. of steps for a particular day? Has Apple missed adding that functionality or am I missing some setting to see it?
