Excellent, full-featured calculator

This is the only calculator I've found that has everything I need and more. I use the five-key memory, automatic constant, and paper tape almost every day. The running total on chain calculations is a nice touch. The calculator also has a pretty thorough list of advanced math functions.

The only thing on my wish list is an "ANS" key. Some scientific calculators automatically store the results of the last calculation in a memory register and display the number when the ANS (answer) key is pressed. That is useful if you need to make intermediate calculations before you use the prior answer, and would be a faster alternative to getting the number from the tape. The existing "=" key is longer than it needs to be. Part of that could be used for an ANS key, which would make an already great calculator even better.

I absolutely love it!!!

It's the best calculator out there, it's free and I use it every day!! What I love about it the most, is that you see every key you type and you can erase one or more digits if you make a mistake, without retyping everything all over again. Also, the result appears automatically without pressing the 'equal' key. If you do press it, the result will be recorded and you can see it anytime later on the tape. I highly recommend it to everybody and I insisted that all my students downloaded it. It's THAT good!!!! Great job and THANK YOU VERY MUCH for creating this app and offering it for free! Thank you!!

My Go Calculator!!

It's an awesome app! Sooo functional! There are 3 great layout choices. What I love most is that whatever function you're doing the answer is showing as you enter the last number! No need to touch the "=" button. You can see the numbers you've entered as you add, sub, etc. Great for checking multiple numbers. How convenient! They thought of the most basic needs for FREE and the ads don't bother me!
