How it works
LangLocker sits between you and your most distracting apps. Instead of scrolling, you learn a few words β then you're in.
Choose the apps that eat your time β Instagram, TikTok, YouTube, or any other. LangLocker locks them using Apple Screen Time and Family Controls.

Each time you open a locked app, a short lesson appears in the language you're learning. Listen to the audio, read the translation, and complete a quick exercise.

Once you nail the expression, the app unlocks for the time you choose. Earn XP, keep your streak alive, and watch dozens of micro-lessons add up.

Features
No new habit to build. LangLocker slips learning into the moments you already spend on your phone.
Powered by Apple Screen Time and Family Controls β the same technology parents use. When an app is locked, it stays locked until you learn.
Each expression takes just a few seconds: native audio, transliteration, translation, real-world context, vocabulary, and a cultural note.
Multiple choice, listening comprehension, word ordering, and pronunciation. Every unlock reinforces what you learned in a new way.
Stay motivated with daily streaks, experience points, levels, and unlockable badges that track your progress over weeks and months.
Set custom time ranges and days so your apps are only locked when you want them to be β during work, study hours, or all day long.
Learn English, French, Spanish, German, Korean, or Japanese. No email, no password β your data stays private on your device.
Why it works
The problem was never the phone β it's what we do with it. LangLocker redirects that reflex into something that compounds.
The average person unlocks their phone around 80 times a day. LangLocker turns each of those reflexes into a tiny, spaced-out study session.
You don't have to quit social media or fight your habits. You simply learn a little before each visit β the friction does the work for you.
Dozens of micro-lessons spread across your day are far easier to stick with than an hour-long lesson you'll skip. Consistency wins.
