Unity Remote 4 Problem

I went on my android to find unity remote 4. I had found it online on my pc. I type in Unity remote 4, unity remote and unity and still cannot bring it up in the search. So working around that problem I sent the link to my android phone and it says "Your device isn't compatible with this version". Then I go to my pc and it says it is compatible. Why would I download it on my pc if it's a android app? I tried to download it on my pc, and it shows options to choose and even when my phone is plugged into usb it's in the dropdown but not able to be highlighted, yet it thinks my computer is a T Mobile phone... Is this a bug? The reason I am trying to get Unity Remote 4 is because the aspect ratio is displaying stretched on the regular unity remote app on the android market when I connect it to usb from my phone yet when I can send the finished build to my tablet it looks fine...I just don't want to have to send it every time and I don't want some smart phones seeing the game incorrectly. Thanks for reading. Please let me know if you have any suggestion about either issue.
