5/5Great Colorful
I like the Big numbers, , and Inerded a adding Machine that was easy to use,and see. Some people said they didn’t like the sound it makes pressing the Buttons, when I read the reviews. But what I gotten was worth the not, and then I thought about it and just turn down the volume. No problem. That solves the problem they were talking about ! Great app I have been using for about a year now , and I’m a 60 years of age, so Senior’s here you go if you need one to see.

5/5Love this one!
I tried one of the “basic” calculators, and it was not user friendly at all. You couldn’t back up one space to make a correction....it only had one correction button, and if pressed you lost everything and had to begin all over again! Very frustrating! This one has a clear button, a clear entry button and a delete button! Love it!

1/5Can’t Turn Sound Off
I’ve used this app for years and have always liked it. I made the mistake of finally updating it for the iOS 16 compatibility and now the sound won’t turn off even with the toggle switch in the proper position. I tried to find the version number of the app before I updated it but it is no where to be found on the screen or under the “settings” tab which is for app screen color changes. It appears people have complained about the sound toggle switch not working but you haven’t made this simple fix that you broke with this version. Why not? I hate keys making sounds especially in this app which is pretty loud. You’ve ruined a perfectly good app. Please fix this!

4/5Great Calculator
As stated previously, it is easy to use. The “backup” capability is very helpful. You no longer have to restart when a wrong number is entered. Large numbers are easy to see and use….however, the answer is smaller. Perhaps the actual numbers could be slightly smaller, allowing the answer to be larger. Just a thought for the developers. I recommend this calculator for its excellent capabilities. It continues to meet my needs.

5/5Simple and effective
I looked at one that wanted $5.99 a month. Seriously, I expect the developers to be compensated for their time but for a simple calculator, not a multi function graphing system, let’s be reasonable. A few bucks for an app, one time purchase, that has simple functions is saving me having to go BUY ONE, is what I was after.
