On Android, through f-droid, there is app called 'NewPipe'. It uses youtube-dl to let you search and watch videos. It can use your exported subscriptions to show you their videos. But the gui is so not interested in keeping your attention, no immediate suggestions and no 'home' page, that it feels rudimentary. You get the bare minimum you need, and no more.
not every video works on newpipe tho. i much prefer its features, but when i want lazybrained intertainment i do find i have to open some links in creepy tracky youtube
