User reviews

Good but could be better

Really easy to use in terms of getting the number out you want. But why does it use the full keyboard? Surely there is a way to just use the keypad with a decimal point?

Other than that very useful!

Response from developer

Hi, we have changed the keyboard to use the number pad with decimal point in one of the previous versions after receiving your request. There is now also a button at the top of the keyboard that lets you put a - sign in front of the number (or remove it) when pressed. This will put a negative sign in front of the number after you have entered the first digit of the number. If there is a negative sign and you want to remove it, just press the button again and the negative sign will be removed from that number.

Awesome

Great app, use it for work.
