Says what it does, does what it says

I got the app free thanks to AppsGoneFree alert but I wanted something like this eventually and while I might not have wanted to pay $3 I would have gladly paid at least 99 cents.
I hate to make suggestions that add complexity to such an elegant, straightforward design but Id perhaps the app would be better one could manually add/paste a starting number and/or be able to copy the current tally (perhaps a long press or swipe across the numbers.)
