About LangLocker
LangLocker is a language-learning app that sits between you and selected distracting apps on iPhone. Using Apple Screen Time and Family Controls, it blocks chosen apps until you complete a short lesson in the language you are learning. Lessons include audio, translation, vocabulary, and quick exercises such as multiple choice, listening comprehension, word ordering, and pronunciation. The app also includes streaks, XP, badges, custom blocking schedules, and support for English, French, Spanish, German, Korean, and Japanese. No account is required.
