Ratings and Reviews
Big keys, pleasing colors, fun to use!
(One of the best calculators out there. 12/10/2018 4 stars for that) I feel your on you way to killing your app. Look around.
Developer Response ,
Thanks for your review! Sorry for the number of recent updates, there were a few minor bugs that got introduced while working on a new upcoming feature, and I wanted to fix those as soon as possible.
Love this App.
I use it all the time on my phone or tablet, it is easy to use and lots of features.
