Needs smaller buttons Needs log2 once there's room for more buttons Needs logGamma so it doesn't overflow Cyx(171,3)

This rpn calculator is exactly was I was looking for and it was free! I appreciate the large buttons and display, which are helpful when using in front of my students in class. In many ways, I prefer this calculator over my hp15c. Thanks.

Can't figure out how to cluck the lower functions of the keys. Instructions not clear. I always get the upper key response Help?

Great app but the update demands iOS 5 and prevents Update All in the App Store from working.

Good. Must know how to use HP RPN calculators! Works great! The negative reviews are mostly from people who don't know RPN and don't understand the calculator

Really like this calculator better than the stock app but for "modern" implementation of an RPN calculator it should really include stacking registers. My old HP has 4 registers and it really helps for longer strings of computations.

Great for EE circuits. Would be nice to have an angle function, and a mag function. What do Cx,y and Py,x do?
