WOW - Amazing Calculator.

I have Space Time Graphing Calc and Pi^3 Calc, but I wanted a simple, nice calc to replace the basic calc for quick basic functions. This app delivers with its clean and nice aesthetic and great features!

Only requests are to please add an option to turn the sound effects off. Also, I'd appreciate an option to use decimals for at least base ten - so I can really just throw away the old calc app.

Well worth it!

Wished I had gotten this before my last TCP/IP class test since it would have made it much easier than doing manual calculations of hex to decimal! Only thing I wished this had was somewhere to switch to basic calculator since I find myself having to switch from this to iOS calculator just to do simple math with percentages and decimals. All in all awesome app!

Just what I wanted!

This calc is amazing. It is exactly what I was looking for! It even looks like the standard iOS calculator, which is really nice. Also, it has a manual that tells you exactly what each feature does. I pretty much NEVER pay for apps, but this is well worth the 99 cents. (Not a paid review)
