All right, Apple I see you

This is nice I mean really nice and people are lazy when they reach you one star review, saying that they can do fractions or do other money in different countries. Also, I saw another app that is just like yours and it for iPad. It had lots of five star reviews, but it just looks like yours, but the things are darker or orange. I love this app.

Very happy with this app. I have used many times and I believe it to be correct 100% of the time. Has all numbers available. 10/10 will use again.
