Blob helps you spend less time on distracting apps and more time living your actual life. Most screen time tools either block apps completely or quietly track the damage afterward. Blob does something different: it adds just enough friction before your most tempting apps to break the autopilot. When you try to open a protected app, Blob makes you pause. You can earn a short unlock pass, or you can walk away and keep your time. That tiny interruption can be the difference between “just checking” and losing another hour. Use Blob to: Reduce mindless scrolling Break the habit of impulsively opening apps Get your mornings, evenings, and focus time back Protect specific apps that steal the most time Track walk-aways, streaks, interceptions, and time saved Make late-night scrolling harder with Hard Hours Unlock apps temporarily when you actually mean to use them And if basic friction is not enough, Blob can get ridiculous. Turn up the challenge level and face harder math gates, from quick arithmetic to algebra, derivatives, and “why did I do this to myself?” mode. The point is simple: if you still want the app badly enough to solve it, fine. If not, you just got your time back. Blob is not about guilt or punishment. It is about snapping out of autopilot before your attention disappears. Get your time back. Scroll less. Live more. All features above require a subscription.
