Quit doomscrolling one urge at a time. Undoom helps you retrain the urge to scroll. When you try to open an app you tend to use on autopilot, Undoom interrupts the habit loop before it takes over. Instead of just blocking the app, Undoom helps you ride out the craving, understand what triggered it, and choose what happens next. HOW UNDOOM WORKS • Pick the apps that pull you in • Undoom appears when you try to open one • Pause before the scroll starts • Name what triggered the urge • Rate how strong the urge feels • Breathe through the craving • Watch the urge fade • Build momentum every time you resist BREAK THE LOOP Most screen time tools only block access. Undoom is different. It helps you train a new response in the exact moment you usually fall back into the feed. You are not just trying to use your phone less. You are learning to stop feeding the loop. BUILT FOR PEOPLE WHO • Open Instagram, TikTok, Reddit, X, or YouTube without thinking • Lose time to doomscrolling even when they planned not to • Feel pulled back into apps by boredom, stress, anxiety, or habit • Want more than another timer or hard blocker • Want to weaken the craving, not just hide the app SEE YOUR PROGRESS Every urge you ride out counts.Track your progress, build streaks, and see proof that the urge can pass without turning into another scroll. PRIVATE BY DESIGN Undoom uses Apple’s Screen Time tools. Your usage data stays on your device. *Requires a subscription to unlock all features.* Terms of Service: https://undoom.latent-studio.com/terms Privacy Policy: https://undoom.latent-studio.com/privacy
