Thanks
Thanks for updating this. It's always worth the odd looks when I use it. I still have my 11c and 15C from grad school and use this more.GJanx
Still awesome
...and now all ready at 64 bit for iOS 11!!!Macroxthesage
Awesome!
This is probably the most used app on my iPhone. I still have my 15C but I'd be lost without this app. Thanks for the update and thanks for making it totally free.BobDetroit
Simply the best
I'm thrilled it has been updated to 64-bit and will continue to be the best for years to come. Long live RPN and the 15c.
Original review 2016 - I was a 15c user for many years. When it finally died a few years ago I learned how difficult it was to find an RPN calculator. I bought one, but always missed my 15c. Now I have it back. This app instantly became my calculator. It is way better than my real RPN calculator.
I'm not sure what, if anything, might be better about the paid 15c apps, but I have zero motivation to pay and find out.Wraggj
