Yattee is a free and open source invidious/piped client for iOS and iPadOS. It’s great for those who want to watch YouTube without the ads garbage. It also supports sponsorblock. It’s a bit buggy, but it still works fine.

I’ve spun up a Debian server a couple of days ago and hosted my own invidious instance. It’s been great so far.

Just a little note, the app looks like it’s struggling with funding/contributions from what I saw on the GitHub and Patreon pages. So if you can code in swift and feel like helping the dev, I don’t think he’ll mind :)
