11C Scientific Calculator

I used the HP 11C in college in my engineering classes. I continued to use the same calculator when I secured my first job, but the buttons began to stick. Then I found this app for my phone. It worked wonderfully well. Well, until my new phone wasn’t compatible anymore. I have waited over a year waiting for the upgrade. And finally IT’S HERE AND IT WORKS LIKE MY OLD HP 11C. Thank you, thank you, and thank you.

It would be a great calculator it I could get it to open! I’ve uninstalled it & it still won’t open. It hasn’t open since the last iOS upgrade 13.2.2. Please fix! I had to go this route since you never answered my email that I sent to your support email. FIX THE PROBLEM Update! I see a lot of people are having the same problem as I am since the 13.2.2 upgrade. We all paid money for this app it’s a shame They don’t fix the problem. You can’t even get support help it also hangs & don’t let you get a hold of them. Mine don’t even open anymore unless I go to the app & press open but that takes a couple of try’s too. I now just leave it running in the background. I WOULD SAY DON’T BUY IT UNTIL YOU SEE A POSITIVE COMMENT ON IT. BUY IT ELSE WHERE!

I bought this app many years ago after my great HP11C finally failed. Loved the app! Gave it a great 5-star review, and I normally do not review apps. Just like the 11C without needing to carry an extra device around. But months ago it would no longer open. Eventually, I gave up and deleted it. I saw in the App Store that it was available again, checked recent reviews that indicated the non-opening issue had apparently been fixed, and paid for it again. It will not open. I’m running iOS 13.4.1. Useless waste of money. I thought the problem had been fixed. Please fix it or return my money. I’d rather you fixed it; it’s well worth the money if it works!

The image of the HP11 is charming, but on my 5s, the letters on the 'g' functions that were on the beveled surface of the physical keys are very small and hard to read. On my HP11 I could just tilt it a bit, but not on my iPhone. This might be fine on an iPad, or a 6+, or for younger eyes than mine, but I think this app appeals mostly to people who used the HP's 30 years ago. There is no means of changing the appearance, which is landscape-only. The HELP takes you to the diagrams on the original back, with no means of expanding them. I'll delete it, and go with one of the many choices that offer screen-appropriate keyboard layouts, some free.

This is the second time I’ve paid for this app and it still doesn’t work(open, stay open etc) The first time I paid for the app was years ago and “this ” e-commerce system no longer recognized that fact by virtue of not letting me leave this review despite the fact the app was on my phone. Reluctantly I decided to buy the app again thinking it might reset/update/ fix whatever the current issue is with the app not opening but that was a mistake. So now I’m looking to see how to get a refund. I enjoyed using the calculator...it was my go to app for crunching numbers. It’s a shame the support for this app is non existent.
