This is another wonderful piece of software from FOSS advocate FUTO.
Aside from another method to bypass YT ads, you can watch your favorite creators on a wide variety of platforms, all in a single app. No complicated configuration required like ReVanced. You can export your subscriptions list from Google via Google Takeout, or from FreeTube/LibreTube/New pipe etc. and when you open the file it should automatically open in GrayJay.
You can also perform cross-platform searches.
PeerTube does work but it uses the FUTO instance, which does not federate, so you can only watch/search FUTO videos. Some work is still needed in that area, but it’s probably also the least popular platform sooo…
This is a paid app based on the honor system and currently only supports Stripe for payments. It’s a 1-time $10 fee.
Futo also makes a casting app called FCast so you can cast videos from this app to your Android TV box after installation.
