I like it. It's solid on a mobile phone but a bit hit and miss on desktop. Good alternative to FreeTube

I have it on my phone but don't watch YT on mobile frequently. It works well enough though when I do use it.

I dont have youtube so i use it as my main mobile video viewing app. So far im happy with it. I have the youtube and odysee plugins. Devs also seem to be responsive and helpful on github, as i found out when i did a derp i thought was a bug but wasnt and opened an issue.

Overall a solid app, good to have as a backup whenever Youtube introduces changes that break the NewPipe mechanism. Fine on larger screens like tablets, but the UI can get a bit busy for my taste on a phone. They say it's merely source-available, but I won't belabor it since I trust the developers' intentions.

I use Freetube and I'm happy with that, but I"ve seen people say a lot of good things about Grayjay.

I'm enjoying it. I like it's sync feature, so now my history and playlists etc are shared across my 3 main devices. No issues so far but still relatively new to it. I find it's more reliable across vpns than newpipe or freetube.

It is pretty good, you can watch videos from different plarforms. Mobile looks solid to me. Desktop doesn't have picture-in-picture, which sucks, cuz I like having a little screen in the corner as I work. Other then that, grayjay is pretty good.
