Just perfect

There is so far no better investment I have made on the App Store, I've been an apple user for 8+ years and this is my very first review I've written. I am yet to encounter any problems and if you are either in college or financing this calculator is perfect for you. Personally, I'm in college and I seriously doubt that I will ever encounter an equation that this calculator cannot handle. 10/10


Skin pack

Skin color orange doesn't work. Only reason I bought this calculator because it reminded me of LCARS. Please fix and yes I bought the skin pack.
