Focus Flow is a strict, OS-level productivity app that protects your deep work. Unlike weak browser extensions, it blocks distracting websites system-wide and auto-closes blacklisted apps. Set a timer, play the built-in Lofi, and get to work. Want to quit early? You must manually type a motivational pledge—adding just enough friction to stop procrastination. No subscriptions, just a $4.99 one-time payment to reclaim your focus.
