Great App

Having tries loads of apps for iPad pro (no native calculator app installed) I came across this one. I Paid £3.99 for this one and Stacks, which came as a bundle. Have been using this for a while now and have found it to be faultless. Does everything I want very very well. Simple to understand and use. Have downloaded it on my iPhone and now use both these apps as my default calculator and currency convertor. Also saving bookmarks and values are essential and when you have the app on both the iPhone and iPad the syncing is seamless and quick. Also work excellently with the Apple pencil. Would recommend this app without any hesitation.

Love It

I have lost count of the number of different Calculator apps I have tried. This is the best I have found. The design and functions are extremely well thought out - it’s very slick to use. Best of all (for me, at least) is that it has everything I need and very little that I don’t - i.e. it’s very powerful but it’s not over complicated. If you need lots of very advanced or specialist type functions then maybe it’s not for you but, I would strongly recommend this for anyone seeking a top-notch calculator for everyday use.
