It does everything I need it to do

I have had a lot of adding apps. Most falling short of promises. Yes it costs to upgrade, which I did. I use this each day. Adding up long lists of numbers, saving it with a file name, and emailing the file along with printing it. If I make a mistake, just delete the line. Forgot a number, just add a line. Where ever you want in the tally. It’s one of the few apps I truly use most of the features.
