Love seeing what I typed on the tape!


I do simple calculations all day long and it is really easy to enter a wrong digit. I really love that I use the “tape” to see what I typed so I can make sure my inputs were correct.
I looked at all the calculators in the appstore before I reached in my pocket to pay for this. I tried another one for many months that stored the tape in a tab on a separate screen of the calculator, but it is much better to see it in real time as I type.
I’d like to see a little more refinements in the color of the calculator so the program feels more appleisk.
Also, I would like to be able to close the app and have it save what I had in it so when I reopen the app it shows the previous calulations. The previous calculator I was using did that.
Thanks for the great work on this.

Saves real estate on my desk

I purchased TapeCalc as a replacement for my ancient behemoth printing calculator. Loved the old calculator, just not all the space that it took up on my desk.

TapeCalc meets many but not all of my requirements. Overall I love it. It does take a little getting used to. I do wish that it had some memory options and that it would configure to 2 decimals without having to add “00” or a period.

For $10, how can you go wrong?

If you liked Judy’s TenKey, you’ll LOVE this one!


First of all, thank you for the all the updates correcting various issues. I am a 25 year PC user and recently switched to a MAC so am always on the lookout for programs to replace those I loved on the PC. One of those programs was Judy’s Tenkey. I’ve tried several calculator apps, but this is THE closest to Judy I can get. It’s a great app and worth every penny. I use it daily.
