This app is a simple calculator for coordinates and time. The app is easy to use because it specializes in calculation of the coordinates and the time. Therefore if you tap a button once, can convert degrees-minutes-seconds into seconds and can reverse convert.

Moreover, if you tap a computation on the screen, the app copies a computation string to a pasteboard (a clipboard). If you tap or swipe a numerical expression, you can use a calculation history which is able to record maximum 1,000 records. In case you use only the “second mode”, the app is the same as a pocket calculator with displaying the expression.

■ Hint to use with a colon

“4:” = “4::” = “4:00:00” = 4 hours = 14400 seconds
“:1:30” = “0:01:30” = “90” = 1 minute and 30 seconds = 90 seconds
“1:61” = “2:01:00” = “7260” = 2 hours and 1 minute = 7260 seconds
“1.5:” = “1:30:00” = “5400” = 1 hour and 30 minutes = 5400 seconds
