Your phone is very good at keeping you scrolling. Quizlock puts one question in the way. Choose the apps that eat your day and Quizlock locks them. To get back in, answer a question about something you actually chose to learn. Correct answers bank scrolling minutes. Those minutes drain while you scroll, and when they run out the lock comes back. You pick what you learn Type any topic and Quizlock writes questions from it. Import a PDF, lecture notes or a textbook chapter and it asks about those instead. No generic trivia, nothing you did not ask for. Built on how memory actually works Questions come back on a spaced schedule, so what you learn survives past the moment you answered it. Get one wrong and Quizlock shows you why, then brings it back sooner. The lock is real Quizlock uses Apple's Screen Time system, so the block holds even if you close the app. Your choices stay private: Apple's picker means Quizlock never learns which apps you selected. Free, with limits One topic and 30 minutes of earned time a day, free. Quizlock Pro lifts the caps with unlimited topics, unlimited PDF imports and your own earn rate.
