Found the calculator that meets my needs, easy to use, and easy to access (as a widget on iPad). Its been a few months since I’ve gotten this app so I can’t remember if I paid anything for it or paid to get rid of any ads, but I can tell you that IF I did pay anything for it, it was completely worth it for what I get out of it. Since the iPad unfortunately doesn’t come with a calculator app, standard like the iPhone does, I checked out the AppStore and found two other ones that were horrible in contrast to this app. So if you are at that point where you’re trying to choose one, this is it. Last point I’ll make is actually the least important thing about any calculator and that is how this app is visually pleasing.

Calza 3 Calculator is Great for ColorBlind

This calculator is full of great features others do not have available. Plus it is very simple to use... especially for me a partially colorblind person!!! Many many apps are designed (without consideration for the extremely large number of colorblind males) using the most difficult colors for the average colorblind person to see. The Calzy 3 Calculator is a blessing for me as a Color Blind Person. Now if Companies like McDonalds and others who use LED Ordering Displays would only consider not using the hardest colors to design menu ordering displays! All APP Developers should consider the ColorBlind people who want to use their apps. Thank you for this Convenient Easy to See Calculator!
