Stop rotting. Start growing. Most screen time apps just lock doors. RotStop helps you earn the key. Reclaim your focus, repair your dopamine levels, and turn your recovery into a high-stakes game. RotStop is the first system-level monitor that treats the cause of doom-scrolling, not just the symptom. Watch your Brain flourish in real-time as you choose growth over the scroll. Whether you’re fighting a social media habit or seeking deep work, RotStop provides the visual nudge and hard friction you need to stay in control. WHY ROTSTOP WORKS: Most blockers are easy to ignore. RotStop gamifies your focus by introducing a "Credit Economy." Want to scroll? It’ll cost you. Out of credits? You’ll have to earn them through real-world productive habits. Save hours of wasted time, eliminate brain fog, and finally finish what you start. WHAT YOU GET: The Brain Score: A live 0-100 score that tracks your mental clarity. Watch your avatar evolve from "Rotted" to "Thriving" based on your daily habits. The Credit Economy: Earn "Brain Credits" by logging offline activities like meditation, deep work, or reading. Spend them to unlock your distractions. The Gauntlet Unlock: A mandatory friction window that forces you to "think twice" before unblocking apps. No more mindless clicking. App Shields: Instantly block social media, games, and full app categories with zero workarounds. Performance History: Track your weekly brain health with our high-fidelity reports. See your "Peak Days" and total hours saved from the void. PRIVATE & SECURE: Privacy is our core. RotStop uses Apple’s official Screen Time API. All monitoring, scheduling, and app blocking happen locally on your device. Your browsing history, app usage data, and personal statistics never leave your phone. We don't want your data; we want your focus. *All app features, including app blocking and screen time tracking, require an active paid subscription.
