12C emulator stands the rest of time
LAX20531
I first began using RLM’s HP emulators when I purchased my first iPhone; that has to be at least 10 years ago. The app has continuously evolved and been updated for compatibility with larger displays and OS requirements. I’ve tried at least five 12C emulators and have always returned to this app because there is no lag with data entry, calculations are fast, and I’ve yet to find a bug. My questions to the developer have always been responded to quickly and in an enthusiastic manner. I don’t mind paying annual subscriptions for the apps that being me value. It should have been obvious to Apple when App Store was in its infancy that one-time purchases of apps for $0.99 would not create a sustainable business model for developers which explains the sea of abandonware that resulted. This app is a small price to pay to keep it sustainable and compensate the developer for his efforts. I highly recommend it.
Developer Response
Thank you very much for your rating. It encourage us to build top quality and usable calculators for iOS.
Portrait orientation doesn’t work on iPad
Qwertasdfgqqqqq
Very nice calculator. Only issues I’ve seen are that portrait orientation doesn’t work on my iPad and show registers doesn’t work (shows briefly, then disappears). Issues aren’t deal breakers. Calc worth the money.
Developer Response
In the iPad, the portrait layout is shown only if you have a Split View that reduces significantly the width of the app respect to the height available. The default and preferred layout is landscape as the real world HP-12C.About the Registers, they are shown if the option is set to ON in the Preferences (g PREF) and no menu is shown in the screen side area (toggle with the OPT key).
What happened to the left arrow key?
TedKennedy
This is a Great calculator. I thought that the left arrow key had been replaced by the CLX key, but I found out that there are options to set the behavior of the key. Everything is great again!!
Now you can listen music while using the calculator.
