PUT IT ON ALL YOUR DEVICES !!! Been using RPN's since before HP-28S came out. Never liked to key in every operation (+,-,×,÷) & then finish with (=). If you used the result you did it all over again!! You'll love all the conversions that are offered from the kitchen liquids, solids, land, scientific, etc. It's all here. Any level of mathematics & you'll be able to solve it completely here. You have ? 100 registers to store results. Try it & you will use no other calc app !!
The only one to get I use it primarily for trig and conversions. Must have app. Would like to have D°M'S"<-->D.D° otherwise this is a perfect calc app.
Great Calculator I've been using this app since before there were apps and before Android even existed. I first used it on Windows Mobile 2003 when it was the best reverse polish calculator I could find. Over the years it has steadily improved and does all I want and more.
This is a good one I started using RPN when I got an HP11c, which I still use today, it is an efficient input system for a calculator. I have used NeoCal since I got a blackberry and this is the best version yet. . Good support from author is icing on the cake
Best calculator My HP calculator died and needed to replace it. This is absolutely the best calculator I've seen. It also does excellent at conversions.
Great calculator I'm an rpn guy and this gives me a lot of functionality in the free edition. If I were using it more, I'd likely pay for the full version.
