How it works

Turn every app you open into a lesson

LangLocker sits between you and your most distracting apps. Instead of scrolling, you learn a few words β€” then you're in.

1

Pick the apps to lock

Choose the apps that eat your time β€” Instagram, TikTok, YouTube, or any other. LangLocker locks them using Apple Screen Time and Family Controls.

Learn to unlock

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.

LangLocker β€” Build your streak

Features

Everything you need to learn without trying

No new habit to build. LangLocker slips learning into the moments you already spend on your phone.

Real app blocking

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.

Bite-sized lessons

Each expression takes just a few seconds: native audio, transliteration, translation, real-world context, vocabulary, and a cultural note.

Four ways to practice

Multiple choice, listening comprehension, word ordering, and pronunciation. Every unlock reinforces what you learned in a new way.

Streaks, XP & badges

Stay motivated with daily streaks, experience points, levels, and unlockable badges that track your progress over weeks and months.

Blocking on your schedule

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.

Six languages, no account

Learn English, French, Spanish, German, Korean, or Japanese. No email, no password β€” your data stays private on your device.

Why it works

From doomscrolling to fluency

The problem was never the phone β€” it's what we do with it. LangLocker redirects that reflex into something that compounds.

Dead time becomes study time

The average person unlocks their phone around 80 times a day. LangLocker turns each of those reflexes into a tiny, spaced-out study session.

No willpower required

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.

Small sessions beat long classes

Dozens of micro-lessons spread across your day are far easier to stick with than an hour-long lesson you'll skip. Consistency wins.
