This is garbage!

In short, this is a calculator you are expected to go online and look up your model of device and it's battery capacity plus the possible and actual drain on the battery in order to get any information whatsoever for $0.99I expect this to be automatic. I am very unhappy/want a refund!

Out of order!

Feel like the vending machine just ate my dollar and didn't give me my Coke. This app does nothing. Literally. No numbers. No data. Nothing!! Consider an out of order sign on this app.
