Well organized and easy to use.
Would be 5 stars if not for the number pad.
Starts at 1 in the top left corner, 4 in the middle row, and 7 in the bottom row.
This drives me nuts because Im a touch-typist on my computer keyboard where the num-pad starts with 7 in the top left corner, 4 in the middle row, and 1 in the bottom row.
Plus our phones use the same layout as the computer keyboard when dialing a phone number. This is the standard, but this app doesnt follow it.
