## What is LockFeed?

Earn your screen time with a little learning.

LockFeed puts a short learning challenge before the apps you choose. Pick a quiz, choose how long each unlock lasts, and use Apple Screen Time to add a pause before you scroll.

HOW IT WORKS
• Choose the apps you want to lock.
• Pick a quiz and an unlock duration.
• Complete a challenge to unlock the app you want to use.
• When your unlock time ends, the app locks again.

FIVE FREE APP UNLOCKS
Try five successful quiz-based app unlocks. After those five unlocks, Lifetime Access is required for further unlocks. Each earned unlock lasts for the full duration you chose.

LIFETIME ACCESS
A one-time in-app purchase enables unlimited quiz-based app unlocks and standalone quiz practice. Standalone practice requires Lifetime Access. There is no subscription, and the price for your region is shown before purchase. Restore Purchases is available for previous buyers.

FIND SOMETHING YOU WANT TO LEARN
Practice vocabulary, identify famous artworks and country flags, solve chess puzzles, or find notes on a guitar fretboard. Explore short practice questions in math, science, exam preparation, driving theory, and citizenship.

One selected quiz applies across your protected apps. Change subjects when you want or adjust your unlock duration. Quiz content is bundled for offline use, and no account is required.

LockFeed uses Apple Screen Time permission to manage access to the apps you select. Short practice quizzes are learning aids, not complete exam preparation courses or official exam simulations.
