Full description

QuizLock turns the time you lose to scrolling into something you keep. Choose the apps you lose time in and set a daily limit. When you reach it, QuizLock locks the app and asks a question. Answer it and you are back in. That is the whole idea — the phone does not just say no, it asks for something small in return. WHAT YOU GET • Screen-time limits for the apps you choose • A lock screen with a real question, not a guilt trip • 84,000+ questions across nine categories, in seven languages • Vocabulary practice in seven languages • Questions you get wrong come back on a spaced-repetition schedule • Practice any time to bank minutes you can spend on a future lock • Day streaks, with a protection that covers the day you forget • Per-category accuracy, so you can see what you are actually weak at • A morning summary and an evening reminder — both optional YOUR DATA STAYS ON YOUR PHONE Screen-time measurements, the list of apps you monitor and your quiz history are stored on the device. We have no servers and no accounts. You can export a backup file whenever you like. IN A HURRY? Watch a short ad to skip once, or spend minutes you earned by practising. Premium removes ads and adds automatic backup. QuizLock is a digital wellbeing tool. Usage Access is used only to measure the apps you choose; the display-over-apps permission is used only to show the quiz.
