Ratings and Reviews
Update to my review below. The more I use this calculator app the more useful I find it.
Previous review: This is a basic calculator, with a few extras. The history, being able to use the history results, and being able to send the history to ones email is most handy.
I've not had this app long, but it has become my go to calculator, except on the rare occasion when I need to use a scientific calculator. The simplicity of this app is what makes it so handy for 90% of what I need a calculator for, coupled with the history it is one of my most used apps.
Finally a calculator with a history panel right next to it!
Many calculator apps do not show your calculating history by default. You always have to push a button or two to view your previous history. I found this app’s interface more helpful, because it is easy to make a typo typing on a virtual keyoboard on your iPad or iPhone, and viewing what you have typed previously helps tremendously to eliminate any errors. Great app!
Does what it advertises
This Calculator is great. It does exactly what it’s supposed to do: it calculates, and has the tape area at the top to show what you’ve done. It lets you correct your mistakes if you’re typing something in incorrectly, without erasing the whole thing. The ads are not intrusive. Overall a very efficient calculator.
