Keyboard default

I love the concept of the app but hate that it doesn’t default to a numeric 10 key keyboard. It is so frustrating to enter a number, hit space, hit the number shift, enter another number, hit space and it always goes back to a word keyboard. Fix that and this would be a 5-star app.

Free apps do much more

There are several free apps that do everything this does and more. They are also more user friendly.

Could be better

It's okay. A little clumsy. Should put up the number pad that is used for dialing with all big numbers instead of qwerty keyboard, have to keep changing to numbers after entering each number. Should have a "clear all" button, have to set cursor to end and delete all numbers backward. Would rather it list the numbers down a column instead of across with a space between each.... Could be better.
