Does this work for mobile? Like am I able to download this tool and it will work on my Android device?
Not at the moment. I’m working on a companion app for mobile devices that will be released in the near future (it will be included as part of an update), but that app will still require a PC running Rich Presence U over your local network.
There is a different application that currently works on mobile devices using some workarounds, not made by me but appears to have Rich Presence U’s database implemented on it, so you should have access to the same games that my app has. Here’s a link to their repository in case you want to give it a try: https://github.com/dead8309/Kizzy
