You need this
This is without a doubt the best calculator ever.
Easy to use
Have been using this calculator for some time. Nice display and easy to use.
Good but needs some change.
It would be awesome if it had the "answer" button. This button will help to operate our last answer directly.
Nothing free
Nice catch to install and then charge for it, recommend to be upfront on cost, very dishonest to suggest app is free when in fact is not thanks
