I had this app on my galaxy s5 and I loved it. Helped a lot with my homework and just simple to use, well if you've had practice with the actual calculator before. I switched my phone to a galaxy s7 edge but now it won't let me download the OS file and I just can't use it anymore. I have the app on my phone but I can't get any calculator because of the OS file. If anybody has any idea of what I can do please help. Or if it's the app version or something. Really want this app back it was super helpful. ***UPDATE**** Finally the problem is fixed. I was able to download it to my newest phone and it opens. It is very handy and helpful.
Update fixed a lot of issues I have been using this emulator for about 3 or 4 years now. It has always worked great but then over the past two weeks it was buggy and wouldn't respond after a while. I tried using different ROMs and reinstalling the app but nothing helped. Just got an update last night and now it is back to how it used to be; flawlessly working. Great application, love using it.
I don't know why this app doesn't get a better rating. The calculator is exactly the one that costs $100. It works like the actual one. For those algebra 2 people who doesn't have a graphing calculator but has a electronic device like a touch screen phone or ipad, get this app. This one is for free. It's better than paying a hundred dollars for a graphing calculator. This should get at least a 4.5.
This is fantastic, this deserves a whole lot more feedback. I am returning to this app after needing to take calc courses and it saved me a lot. So happy to see how well they've updated it! No need to browse the web for the needed ROM file as before, they embedded the easy access feature in the app itself. 10/10.
2015-2016: working just fine, amazing grades of any level!! Great for school or regular use, whatever you want, wherever you want! Just amazing, one of the best calculator apps I've had. Four or five stars (sometimes glitches, but otherwise no problem). ***Edit (January 2017): stopped working for a while. Tried reinstalling it, but different version from last one, again today. Found that it's working. I think it was the ti-84 calc that stopped working.
Downloaded this which was highly recommended by my algebra 2 teacher, it asked if I had a ROM file, which I don't, and I selected the button that said to help me create one and it does nothing. I'll let it sit there for half an hour and nothing happens. I uninstalled and re-installed to make sure it wasn't my phone, and it still will not work.
