Give YouTube ten or fifteen minutes per day, then let Screen Time shield it after the limit is used.
YouTube limits
Block YouTube on iPhone when it stops being useful.
YouTube can be useful in small doses and costly when it turns into a loop. Focus Blocks lets you choose a daily YouTube budget, a blocked schedule, or both.
What to set up
Block YouTube during deep work, class, or morning startup hours.
Allow YouTube only inside a chosen window and still cap total use for the day.
Why Focus Blocks fits this job
Focus Blocks uses Apple's Screen Time APIs, supports websites like youtube.com and m.youtube.com, and keeps app selections private to each device. No account or tracking is required.
