Very nice app, I like the way it adds and subtracts time for my log book

Can't subtract time. It only ADDS. I tried to calculate difference between my start and stop times for my total block time -and it doesn't do it. It only adds time. Also, fuel input is all in kgs. You can't change the settings for inputting in US gallons or Pounds. Don't buy this app. It's a waste.

Works great! Now I just need it to be updated for ipad
