Best business calculator and everyday use

Awesome product

I’ve been using this calculator for over a decade. It stays updated and is extremely useful and powerful. I primarily use the financial calculator functions. It is quick and easy, and it’s always at my fingertips. I haven’t put batteries in my old HP stand alone calculator in so long that I don’t even know where it is anymore. It really is a great product, both on my phone and my iPad.

Perfect for CFP exam

I bought this app almost 10 years ago to help me study for the CFP exam. While you cannot bring your phone into the actual exam I found this app to be very helpful when studying.
It is a great display, very easy to look at. I found this app far easier to use than my HP 10 Bii + financial calculator.
I use it everyday.
