For me, Google video search, Google books (Internet Archive is good, but doesn’t always have the same stuff), Adobe InDesign (but in the process of learning LaTeX), and Typewise. As for the Google stuff, I liked Whoogle a lot, but almost all their instances seem to have been blocked or shut down. Also, apologies if this is repeating an earlier post.
Youtube doesn’t let you listen to videos if you navigate away from the app or lock your screen, making it functionally useless as a mobile music player. You have to pay for YT music to be able to do that.
And I agree with you about not using spotify, but again, there are certainly advantages to it. The pros just don’t outweigh the cons/match our values.
I think you can do that with Invidious or FreeTube…? NewPipe will let you do that, I’m pretty sure.
Sure but they are not as effortless/not as feature rich as spotify and can be tricky to run on iOS. Google et al are also actively trying to break those projects these days. I say this as a daily freetube user.
