I tried using time limit on apps, but it just asks you whether you want to bypass it 
Is focus the same? Can it be easily switched off?
What I did recently was block YouTube and this has been a big help. I find it easy to delete apps like TikTok because they are purely entertainment based, but YouTube is dangerous - because it contains so much useful stuff/info too. However I really don’t like how the new CEO basically told all content creators to make vids at least 11 minutes long (so they can serve more ads) and now there’s just so much crap in videos just to meet this length. It’s become common where 20 seconds of actual useful info is piled into a 15 minute video. YouTube should be ashamed of this - what was once a useful and often educational platform is now literally wasting years of people’s lives, and for nothing more than greed
