About

Scroll Ladder

Read full description

One ladder is now free forever, with no 24-hour limit. Pro unlocks up to eight ladders. Paid skips are always available without a Pro subscription and are charged separately. Stop opening distracting apps on autopilot. Choose how you earn your next 15 minutes. Scroll Ladder blocks the apps and websites you choose, then opens a timed access window when you complete an allowed unlock method. HOW IT WORKS 1. Choose apps, websites, or categories. Start blocking immediately or after a daily free allowance. 2. Set your allowed unlock methods and a 15, 20, 30, 45, or 60-minute access window. 3. When blocked, choose an enabled method to open access. Return to the protected app yourself. A LITTLE MORE EACH TIME The first math unlock asks for 1 question; the first movement unlock asks for 5 reps. Each completed unlock raises the daily step. Choose from five math difficulty levels and 10 movement exercises, including squats and jumping jacks. The ladder resets each day. Paid skips are separate consumable purchases. Each opens one access window, with the price shown before purchase. The price rises with the daily step and caps at step 4. No account is required. Protected selections and activity history stay on your iPhone. Movement video is processed on device and is not saved or uploaded. Screen Time authorization is required and can be revoked in iOS Settings. Set up your first ladder and make the next open intentional.
