Customer Reviews

Helpful with basic calculating needs

I've had this app for quite awhile now. It meets my needs for a basic calculator but do wish it had a % function (Ex: 50 + 23% = x). A couple to things I really like it the ability to change font sizes and the 'paper tape' that makes it possible to proof the figures you've entered. It is especially helpful to be able to email the paper tape to yourself for archiving purposes. The calculator fills up the whole screen which makes it easy to see and enter numbers on. Overall, a very helpful app. Thanks.
P.S. Not crazy at all about being plagued with reminders to rate the app.

Perfect free calculator app

The two biggest selling points: No obtrusive ads (just a little strip at the top) plus the calculator takes a minimal amount of storage space on your device. This has less than 1/2 the MBs of most of the other free calculator apps and it does the job. It has a good size number pad, plus it has a paper tape as a nice bonus. I'm glad I found this app.

Great calculator app!

I use this app regularly. I love that you can keep a running tape and enter descriptions of what you are calculating! The only thing I would improve would be the ability to print directly from the app (perhaps you can but I haven't figured out how to do this?) however, you can email the tape to yourself and print from there.
