Long story short, Google Play is a pain to get apps uploaded to. So, if you want to use the app, this is the best I can do right now.
1. Click the link and download the app file. (Some phones require long press and open in new tab)
2. Allow installation from your browser.
3. Open the app, and you're good to go!
There will be a bunch of warnings, as they cannot guarantee the file. I can. It's safe, I promise.
