What is your must have open source application available on fdroid?
New pipe - the YouTube front end is absolutely critical for my lifestyle.
NewPipe for Sure. Normal YouTube apps is bloated as hell + NewPipe is very nice to listen music
NewPipe has only one problem: the inability to log into your Google account and keep your subscriptions and watch later playlist synced.
“Problem.”*
Those of us who degoogled see this as a pro not a con.
I’d also blame youtube, iirc there is no way to export your playlists to a .csv, which could then be imported to something like newpipe easily. Of course, youtube doesn’t want to let you do that because the only thing keeping people from newpipe is really this “sunken cost” aspect to it.
You can export YT and YT music subscriptions in CSV format on google takeout: https://takeout.google.com/settings/takeout/custom/youtube
