Firsthand evidence
Limitations and fit
- QuizScreen requires iOS or iPadOS 17 or later and Apple Screen Time permission.
- The quiz is completed inside QuizScreen; Apple controls the system shield shown over a blocked app.
- Core app blocking, every unlock duration, and the built-in offline quiz packs are free with no unlock limit. AI-generated and custom-topic learning features require Premium.
- A blocking tool can add useful friction, but it cannot guarantee better grades, focus, or health outcomes.
- This comparison was reviewed on 2026-09-06 and uses Opal’s public documentation; it is not an endorsement by Opal.
