One problem I have with all these self control style apps is that they only let you set total per day hourly limits. My intuition is that if you give yourself a two hour, one hour, even 30 minute limit per day you're still liable to drift into zombie mode and are more likely to want to unblock after that long brain rot session. My ideal blocking app wouldn't restrict your total per day, instead the key feature would be that you can only scroll for 5-10 minutes at a time with a cooling off period. That is, if you scroll for 5 minutes you then have to wait X minutes before you can scroll again. I think this should have a strong c-c-c-c-ombo breaker effect without giving you enough time to get hooked so badly that you immediately want to bypass it.
