Please fix the os error. The first time I downloaded the app it worked fine and I'm in love with it, it's really helpful. However now that I'm trying to download the os file in a different phone it says that the file can't be downloaded and there was an "error". Please look into this and fix the problem, this is a really helpful and convenient app, especially for people who don't have money to buy experience calculators. Thanks!
No Longer Works I had previously installed and used heavily on my previous device, which is the exact same model as my new one (warranty replacement). Of course I want all the apps I used most frequently back, so I reinstall. For any ROM, it says "Error downloading the OS." I have uninstalled and reinstalled to no avail. I'm not sure why this isn't working now even though I had just had it fully functioning just a week ago. ZTE Zmax on 4.4.2
Can't download ROM from TI Texas Instruments has figured out a way to prevent downloading an OS from its website. Without the OS, the app is useless. I am a math teacher, and I used to STRONGLY recommend this app to my students, especially to those who could not afford a TI-84. Has there been any efforts to resolve this issue?
Works perfectly! Our Algebra 2 teacher has us sign out a graphing calculator at the end of the day if we need borrow one, and with this app I don't need to go out and spend $100+ for my own. Thank You for making this :)
Awesome I've been using this emulator for over a year and I must say it is very convenient to use, more so than my bulky graphing calculator. I honestly never use my physical, expensive one anymore. This emulator has all the features AND it's free. I love this app so much! With the update, occasionally it does become unresponsive, but then you can just force it to stop and go back to using it. So it's not as big a deal everyone's making it to be.
The Best Phone Calculator, Period I've always found my TI83 Plus to be the best calculator around: Easy to read & use, very powerful, & practically indestructible. But portability is a problem. With this app, it's as if my favorite calculator & my phone have merged into one seamless machine. Recently there was a problem with RAM resetting on startup, & while that took a long time to resolve, it appears to be fixed now. The ads are so unobtrusive that I barely notice them at all. I'd buy the ad-free version, but it's quite old.
