The all is a bit difficult to understand. Im not sure what the stats mean, as I cant get meaningful correlation using a calculator. One major downside I noticed is my battery life dropped significantly after I loaded this app. I had the phone on all day today with the app off and battery life is still poor. Will unload the app, hoping it resolves this issue. I cant recommend this app from my experience.
