I wish TI would update the original TI-89 and add a backlight to the display for us older engineers! Fortunately, with this app, my TI-89 rarely leaves its place on my desk, yet I'm never without it (unless the app store decides to cause trouble). I do hope the device compatibility update comes soon so I can re-install the app on my new phone. A huge thank-you to Dritan for this app and all the updates over the years! You've made my life & work a little bit better.
App forgets ROM more and more frequently- "Error reading the state file". Requires deleting stored ROM reference in app and digging back through phone files to re-import. Happens almost every other time I use the app now, incredibly frustrating. Nothing changes on my device, the file is always accessible.
This crashed on my new Verizon S20 Ultra saying: "There was an error loading the IMG file. The error code: ERR_CANT_OPEN" 5 stars because this app worked fine for a long time on my other phones with no issues. I guess its age must be catching up on it. Kinda sucks that it hasn't been updated is such a long time, as I was really looking forward to seeing new features such as the legacy nspire cas with touchpad. "Support developers so our beloved apps live forever" No piracy!
