Must have

If you need to add up a list of numbers and verify their accuracy on your phone then this is the app for you! And having the option to Print and/or email the tape to yourself or client with a note is perfect. So many apps stop short of the kind of usefulness this has.

I love this app.

This app is great. I love and could not live without the the running paper tape feature, ability to wrote notes on the tape, this is the best for people who work with numbers and have lots of interruptions. I love it!
