I have real Casio FX-39, this is perfect calculator. The app is great, but not include rotate lock button or checkbox in settings.
I love this. I don't really even have a use for this one, I just bought it because I like the free one so much. If you've tried the free 3D calculator from the same developer, you can expect a similar experience with this one. The calculator is nicely modeled, featuring animated and functional buttons and switches, buttons and switches click appropriately. Program options include lighting, vibration, and adjustments for the display's glow. This one even shows a battery door on the back.
Amazing animation.
Looks great and works just like the fx39 in my draw at home (but with a more reliable + button). Dump the distracting rotating gear icon in the top corner when in full screen.
Amazing piece of work
Nice app
This valculator is not good because its only 8 digit
you might forget you haven't got a real fx39...
Looked perfect on my Note 3, but the 3D bits and pieces, shadowing, etc, looks terrible on Note 4. Needs sorting out...
Awesome awesome. So realistic. Fantastic trip down the roots of my formative geekdom. I've been waiting years for this. Thankyou!
