Bad app
This app is usless. If you want to work out anything under an hour you have to work out the decimal place. Eg 30mins = 0.5 of an hour. That's the only reason I bought the app. Anybody can do simple speed, distance, time calculations in their head. I bought it to work out my speed when they were too complicated for me to do in my head and the app can't even do that. I might as well have just dropped 69p on the floor.
