Improvements needed before 5 stars

I bought the premium edition with ability to export PDF files. The program watermarks their own name at the bottom of the page which is selfish promotion on their part. I don't want their name on my work when I've paid for this application. The controls to edit export etc. are all there I just find them haphazardly laid out.

Great adding machine

I would like to see the feature where I could eliminate the tape and have a bigger “total” screen

So useful

I love this app for complicated and long money columns. No more losing your place or accidental deleting like a calculator. There are a few buggish things that you can finally work around but I couldn’t have done my book keeping without it.

Great Calculator

The calculations are so easy to follow as you work through a list. The ability to produce and store the calculations makes it so much easier. Good app.

Perfect!

I have used adding machine apps on my iPhone for ten years and never liked any of them. This one is perfect! It works like a ten key paper tape machine but it lets me edit a column of numbers to make corrections. Definitely get the upgrade to have 400 lines of numbers. To clear the register double tap the “i” key then tap “clear”. One last time: It’s perfect!
