Set your distraction keywords — YouTube, Twitter, TikTok, Reddit. The moment you visit a matching site, ScreenCurb kills your browser process. No warning. No "are you sure?" popup. The tab is gone. The key feature is Force Mode: lock everything down for a set period. You can't quit the app, can't uninstall it, can't remove blocked keywords — only add more. You threw away the key. On purpose. Built by a solo developer who lost years of deep work to "just a quick scroll."
