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.
This was not clearly described. The app states it will charge your account after 30 days (according to the opening screen). Use caution. Pressing OK to start the trial may commit you to a $9.99 charge. Not transparent and poorly worded in description.
Show’s briefly but then disappears. Works fine on iPhone.
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.
