iOS asks for my Apple ID login when I launch app
Mister Bix
iOS asks for my Apple ID login each time I launch app. Don’t know if this is triggered by app or a quirk in iOS. Solid app otherwise. I highly recommend it if you’re nostalgic for the halcyon days of HP calculators.
Good but ...

As the owner of a real HP 11C, it’s nice. But a couple of nits: The program does not accept input from a Bluetooth Keyboard. I’m not looking for magic here, but it should accept numerics, Period, Enter, Delete, up/down (roll the stack), +-x/. Maybe also C (CHS) and E (EEX), and CMD-Delete (clear stack) Why if one is has paid for the Premium Scientific calc one does not have access to the basic version???
Good so far only one bug.

The month-day-year function doesn’t appear to work. Other than that everything else has worked so far.
Quality product!

I have spent quite a bit of time with the software engineering calculator, the 16i. I have discovered ZERO problems to date, BUT of course, as a software engineer, I have to admit that guarantees ZERO. So far, it appears to be an excellent, quality product. I'm glad to know the HP-16C lives on.
Classic RPN HP emulators

HP-16c emulator works exactly like the real one. A really useful app that one doesn’t have to learn. The real device & the app are the same. One nice extension for the app would be to show the stack contents in place of the ads once the version is purchased.
Solver error
psb22
Solve e^2x - 3e^x + 2 = 0 Input range of .1 to .8 gives the correct result same as a real 15C Input range of 0 to 1 and the real 15C says 0 which is a root. This app returns 1 which is incorrect. I now wonder what other bugs are in the solver. The bug has been fixed. Thank you!
Keeps promoting for my AppleID password
MacJohnMcC
Frequently when I start the app I am prompted for my appleid password. This behavior is unique to this app.
Why does this app keep asking for my iTunes password?

Will delete if it isn’t fixed in update.

So far, so good! It looks exactly like the trusty, old 12c and functions just like it. The biggest (and only) drawback is the ad that pops up a few seconds after you open the app but that's to be expected from a free app (you get what you pay for) For a free, perfect imitation of the 12c, this is a great app.
