Touch Fin RPN is an RPN financial and scientific calculator that implements most features of the industry-standard HP-12C, including programming functions. It also implements a scientific RPN flavor that implements most functions of the beloved 11C. And even more flavors (10C-like, 16C-like) can be purchased within the app.

Free version OK, paid version ripoff

The calculator app itself works well enough. In fact, to the point that I went ahead and paid to get rid of the ads. It claims to have family sharing, so I paid using my iPad. When using on my iPhone, which is more typical, I still have the ads! And you can’t pay for it again on the phone because Apple figures the app was already paid for.I’ve tried multiple times deleting and redownloading and rebooting phone. Reset purchases from the Settings screen does nothing. I even tried purchasing again direct from iPhone but Apple doesn’t allow and says it was already purchased, so at least Apple is protected the user.

Sometimes the App Store takes a while to send the receipts of purchases to a new installation, it has been happening more frequently in the last few weeks, Internet congestion I guess. Try going to Settings and touching the button 'Restore purchases', reinstalling the app, or restarting the phone to force the app to get the purchases.

Where’s the paste?

I love this app, and bought two versions. I love the fact that the scientific version allows both RPN and ALG. Any chance that feature could be brought to the Financial versions. Switching back and forth all day can be confusing at times and I don’t have the luxury of using only one calculator. Second question (feature request?). I love the ability to copy to the clipboard and use it fairly often. But even more often I would like to paste from another app INTO the touch calculator. Is that possible? Have I missed this feature?

Developer Response
About the first item, go to Settings (ON -> Settings) then look for "Fast swap buttons". You can configure up to 3 flavors to have fast-swap buttons on the main screen, making it easy to go back and forth between them. More info at the end of this page: https://stendec.io/ctb/touchios/flavors.htmlAbout the second item, this feature is in our roadmap to be implemented.

30-Aug-23 - „User“ Mode Matrix Bug Report
08/31/2023

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.

Thanks for the bug report!

I’ve been using this app for years. Ever since my HP 12c died. It works exactly the same! I had a little glitch in that I was getting the wrong payment for a loan that I was entering. I contacted the developer and he answered right away. He asked if I had the future value set to zero. Somehow it had gotten changed and it was not zero. I set it back to zero and everything works perfectly again. Thanks for the quick response! I love this app. (I must be happy with it, this is the only review I’ve written about an app so far.)

Developer Response
Good to hear that.
