Calculator´ App Comments & Reviews
Calculator´ Positive Reviews
It’s all that I needThis is the best basic calculator I have found. It functions well and it shows the progression of your work, almost like an old fashioned calculator with a paper readout would do. The buttons are a good size, so not too many “big finger” issues, and they’re sensitive enough to not miss numbers as I input them..Version: 3.5.31
BEST CALCULATOR EVERThis is what I've been looking for for months, expression editor with instant answer, simple UI, fast one, it also came with extra features like keyboard, widget, great settings, clipboard, and everything you need, I didn't even know how much this were important until I saw 'em here, BIG LOVE DEVELOPERS.Version: 3.5.12
Great calculatorA really well made Calculator app that replace the default calculator app on both my iPhone and iPad. Many convenient features, clean UI. Can’t recall any crash in the years I have been using it..Version: 3.6.3
My favorite calculatorI deleted the default calculator because this is better in everyway. It has a great GUI, it shows your calculation as you enter it and it has advance features..Version: 3.5.12
Bait and switch?I downloaded this app as it was featured on appsgonefree this morning. When I downloaded the app, it’s asking for money to add the very features advertised for free. I don’t have an issue with paying for a well made app like this, but something isn’t right with the pricing or someone got their wires crossed..Version: 3.5.26
Price issueThis app was in AppsGoneFree on June 2, 2019. The download was free, and the upgrade was supposed to be free, but I got charged for the upgrade. Not crying over the $2.15, but still not happy about being charged for something that was supposed to be free..Version: 3.5.23
WonderfulI finally found a calc that easily and efficiently replaces the one included on this phone. It works..Version: 3.5.23
Nice one you used to itIt took me a few times to get used to the functionality of the app but once you cross that barrier it becomes a nice tool I use often..Version: 3.5.26

MathGood.Version: 3.6.3
App Gets Better & Better!!I love the new icon, I love the no more crashing and I love all of the cool features that you guys put into this app with at the same time making the app size so small. The only thing that I would change would be to remove the swipe down converter feature on the calculator screen to not get that popup (I paid for this version for a reason), I don't mind it on the settings page but it does get a tad annoying when I accidentally swipe down instead of tapping the box. Other than that small thing, this is a perfect app!!.Version: 3.3.2
Good CalcHas many functions, very good!.Version: 3.5.11
Swipe motionsSwiping down to close the converter doesn't work. And since tapping on the screen anywhere will not return you to the main calculator screen, the app has to be closed and started again just to get away from the converter. This is on iPad mini 3..Version: 3.5.6
Good calculatorWish it had setting to only show simple keyboard..Version: 3.5.11
