Why this exists

  • Doomscrolling is an environment problem, not a willpower problem.
  • The habit happens in the browser.
  • Time’s Up adds friction at the layer where the loop starts.

What’s live

  • Site blocklists and per-site daily limits
  • Category budgets for social, video, news, and other feeds
  • Scheduled downtime windows and doomscroll detection
  • PIN protection for bypass actions
  • Zero data collection: settings stay local
