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!

Seems great but...

It lacks two necessary features that would enable it to be a truly productivity oriented app, as it should be. Here is what I mean:
1) there is no separate all clear button!
Fast inputs require this button to be separately available otherwise it can impede on productivity. I am comparing this app to the stock calculator app as well as a physical calculator and the importance can easily be noticed.
It is not to say that it is not there - it is combined with the regular delete function and the input can, too easily, be unregistered with a slight move of the finger whilst force pressing
2) most importantly it loads too slowly to be used frequently as my main calculator (for business use). I use an iPhone X and the quick launch feature of Apple’s own calculator bests the launch time of this app by miles. And in high pressure situations this app likely would not be preferred by most.

In other instances, using this calculator is a breeze, as long as it is already opened and you are not in a time crunch. The user interface is pleasing to the eye and the added features are on point.

Just add the two basics and this 4-Star app can easily be a 5-Star app

Amazing calculator

I deleted my stock calculator on my iPhone after using this. I love it. You use your calculator a lot more than you think you do, whether it be calculating a tip at a restaurant or calculating how much you will get paid you use your calculator almost every day and I grew tired of the limitations from the stock calculator especially that if I messed up a calculation I would have to start all over. With this one everything is editable. They say people only leave reviews if the absolutely love something or they absolutely hate it. So the fact that I am leaving this review goes to show how much I love and use this calculator. Awesome product.
