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.
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?
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.
Touch RPN is an RPN financial and scientific calculator that implements most features of the industry-standard HP-12C, including programming functions...
