Sad news: due to forces outside of our control, the Catalyst Player App will soon be delisted from the Google Play Store. If you have the app today, I’m not sure if you can continue to use the version downloaded from the Play Store. There is no online component, so unless there’s a secret Android check to associate the publisher account, the app should function perfectly well offline. You can find the .apk files on the Catalyst page and download them independently of the tech giant’s storefront.
