About this app

LockQuiz is an innovative app that replaces your smartphone's lock screen with quizzes. Each time you turn on the screen, you'll face a question—ranging from math and logic to calculation problems—at various difficulty levels. The lock can only be released after answering correctly. It helps boost your focus and thinking skills, while letting you start your day with a fun challenge. You can choose between EASY, MEDIUM, and HARD difficulty levels, making it a great tool for self-directed brain training.
