Amazing!
I have been a user of HP12C for over 40 years loving the RPN system and this app is as good as the actual HP calculator and thanks to its developer, it’s available on my iPhone. It’s a match made in heaven!

I love being able to easily switch between 12C, 11C, and 16C Voyager emulation. The UI is first-rate and I’ve had no problems with the accuracy of the operation or results.

Calculator works fine. My purchase was ad-free for a few months but all of a sudden I have unwanted Google ads constantly—distracting to say the least. Is the modern version of bait and switch?
I paid for the ad free version but after a while it started showing ads again.
I love these Apps! I got the premium 15c/16c & 12c w/Black-Scholes ones. The only minor concern is on the last one: it replaces the Bond functions with these other ones, but the quick reference card (simulating the back of the calculator) still shows Bond related functions there. It would be better to put some basic Black-Scholes references there. Thanks for all the work on the apps!
Bought the app to remove the ads, and days later they were back and still are. Super annoying and will probably throw this in the trash. Sad as the app works well but the ads, aside from being distracting make the app flicker constantly as they refresh.
Love the App, but paid for the no ad version years ago and am now getting annoying ads. What is up??? Turns out there is a way to essentially restore the purchase Go to the Settings panel (key ON, then 'Settings' at top right corner) and then touch "Restore purchases".
I paid for the no ad version and it just started showing me adds today.
30-Aug-23 – Acknowledge that Touch Fin fixed the error that I found 23-Jul-23. I am the V Brunton mentioned in the current write-up. The error: Not capturing and storing status of „user“ mode in PRGM mode. Appears to be fixed. The only error is in the description of the fix: Text from the write up states that this new instruction applies to STO (I) and RCL (I). To be correct, what was meant was STO (i) and RCL (i), the lower-case i indicating an indirect register (this case, matrix) while the upper case I indicates data going into or out of the index register itself. From what I can tell, the instructions work correctly, just the description has a small error. Kudos for fixing this annoying bug.
