Stop opening distracting apps on autopilot. Scroll Ladder adds a small, growing challenge before you can open the apps and websites you choose. HOW IT WORKS 1. Choose apps or websites to protect. Block them immediately or set a daily free allowance. 2. When access is blocked, choose math, squats, jumping jacks, or an optional paid skip. 3. Finish the current step to open a timed access window. Return to your app when you're ready. THE LADDER GROWS WITH YOU Your first unlock today takes 1 math question or 5 movement reps. The second takes 2 questions or 6 reps. Each later unlock adds one more. Optional paid skips also follow the daily step and display Apple's localized price before purchase. The ladder resets each day. BUILT FOR REAL LIFE • Pick math any time, including when you can't use the camera. • Squats and jumping jacks are counted on your iPhone using the front camera. • Choose a 15, 20, 30, 45, or 60-minute access window. • Review earned opens and moments you chose to walk away in History. • Share a private daily recap that does not reveal protected-app names. • Unlock before editing, pausing, or removing an enabled ladder. Scroll Ladder requires a subscription, introductory trial, or lifetime purchase after onboarding. Optional paid skips are separate consumable purchases that each open one access window. Subscription plans renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. PRIVACY Your protected app selections and activity history stay on your iPhone. Camera frames are analyzed on device and aren't saved or uploaded. No account is required. Screen Time authorization is required to protect apps and websites. You can revoke it in iOS Settings.
