## Study Lock Description
Study Lock blocks your distracting apps until you study. Import your courses from PDF, photos, or plain text, and the app generates personalized quiz questions, flashcards, and oral analysis exercises, all powered by AI.
How it works:
Import your course material in any format.
AI instantly creates quiz questions, flashcards, and oral analysis prompts covering the full content.
Select which apps to block using Screen Time.
When you try to open a blocked app, Study Lock asks you to study first.
Answer correctly and earn screen time as a reward.
The harder the question, the more time you unlock. Oral analysis lets you explain concepts out loud while AI evaluates your understanding and gives you a detailed correction.
Every question follows a spaced repetition algorithm so you focus on what you actually need to review. Your progress is tracked with streaks, mastery percentages, and detailed session statistics.
Study Lock is built for students who want real results without relying on willpower alone. It turns the time you spend on your phone into structured study sessions.
Key features:
AI-generated quizzes, flashcards, and oral exercises from any course material.
PDF, photo, and text import with full-document coverage.
Screen Time integration to block and unblock apps based on study performance.
Spaced repetition scheduling adapted to your level.
Oral analysis with speech recognition and AI-powered evaluation.
Pomodoro timer with Live Activity support.
Detailed statistics including streaks, accuracy, study time, and earned screen time.
Works in any language.
No ads. No gimmicks. Just a simple system that works.
