Limit spans

I was hoping for and would like the ability to limit particular problem apps to about 30 minutes every 8 hours. I don’t need things blocked entirely on a scheduled time, I need some leeway on when I can use my apps. Also, having to talk to and be scolded by this slow talking brain in the app every time I wanna unlock my Instagram to show my friend a picture is so cumbersome, let me push a button and move on. Do these tools exist for me or do I have to use them how Brainrot thinks I should.
