Outstanding app...love the RPN functionality as I used an HP for years that way. Would like to request functionality to switch back and forth from rectangular to polar coordinates. And also the ability to perform addition and subtraction of same. These calculations are required from time to time and have the ability to easy perform them anywhere would be tremendous. Very helpful for vector math used in a variety of scientific and engineering disciplines.

Excellent calculator and unit converter. The only missing feature that lets it down is the lack of rectangular to polar and polar to rectangular conversion functions. These are so useful for anything to do with vectors that I can't give any scientific calculator missing this feature a 5 star review. I suggested this years back, along with using the gamma function to allow non-integer factorials to be found, but the developers have abandoned this app since 2015, so updates are very unlikely now.

Abandoned development I have used this app for many years but unfortunately it seems orphaned now and the last update was more than 5 years ago. Some of the features like happtic feedback and full screen no longer work with the newer Android versions. It is still great and completely usable, but is not as great as it used to be.

It appears I am just like a bunch of other folks. I used the free version for many years. A while ago, I upgraded. My reason wasn't any dissatisfaction, rather, I just decided I needed to support it. I have recommended the free version to RPN calculator many times, and continue to do so. I find this to be better than the hp calculator emulators, and that is saying a lot; I used hp calculators (hardware devices) for decades, and, as much as this makes sense to say about a calculator, I loved t

Like another user, I've used the free version for several years. I've recently used it in YouTube videos I've been making for my physics classes. I purchased the upgrade because I want to express my gratitude to the developers who designed this calculator. I've also used this calculator with some of my severely visually impaired students, and it works very well for them (especially when I put it under a CCTV!)

My go-to calculator since Android 2.x. The only thing it lacks is 64-bit support when in hexadecimal mode. (It tops out at 48-bits.) Allowing for 64-bits in hex mode would perfect this app for me.
