If purchase is for life time and paid for why I keep receiving the message on the calculator screen forcing me to click ok? Pls advice. On else, it is a great product— Tks -- MTmovie, 2025-02-04 ### ***** "What happened to the left arrow key?" 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 I thought that the left arrow key had been replaced by the CLX key, but I found out that there are options to set the behavior of the key.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!! -- TedKennedy, 2025-01-10 ### ****- "What happened to the left arrow key?" I loved the first version of this calculator! Then when I upgraded, I lost the left arrow key so my only option when I miskey a number is to hit CLX and reenter the whole number - what a pain in large numbers!!! Why was the left Arrow removed!! Bring it back!!!! I hate the CLx key. -- TedKennedy, 2025-01-05 ### ****- "Great app - issue with Logitech MX Keyboard" This is a great app. Wish it stayed free like others. The ENTER key on Logitech MX Keyboard doesn't work. Have to use the Return key to enter values. -- BottomLinist, 2024-11-01 ### ****- "Portrait orientation doesn’t work on iPad" 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. -- Qwertasdfgqqqqq, 2023-10-15 ### **--- "Use caution - demo only - after 30 days will charge" 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. -- TreborIke, 2023-08-07 ### ***** "12C emulator stands the rest of time" 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. -- LAX20531, 2022-07-31 [View all RLM-12CX reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## RLM-12CX In-App Purchases | Item | Price | |------|-------| | Lifetime Purchase | $9.99 | | Monthtly Subscription | $0.49 | | Annual Subscription | $5.99 | | Semi annual Subscription | $2.99 | ## RLM-12CX Discovered Keywords -
