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
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.
Thank You So Much I really needed to no 2+2 I thought it was 5 but this calculator showed me it is 4.. I could not have learned this without u.. I wanna thank you from the bottom of my heart for making this app... the kind of bs I make up at 1am lol 😄😄
OS file won't download I've been trying to get this on my Galaxy S6 Active for a statistics class I'm taking, as the professor said we would need the TI 84 plus calculator for some of the more advanced stuff later in the class. I keep getting a message that there is an error with the OS download. This is no use to me.
