iPhone
Learn Mandarin without opening another app. A fresh hanzi waits on your lock screen, and your social apps stay sealed behind a quick quiz until you earn the scroll.
Lock In Chinese turns the time you already spend on your phone into Mandarin you
actually remember.
A new Chinese character waits on your lock screen. Glance at it while you wait for
coffee, and the reading sinks in without a study session.
When you reach for a distracting app, Lock In seals it behind a two-tap quiz: read
the character, pick the meaning, and the app opens. Three in a row earns your scroll
time. It is a gentle gate, not a punishment, and you choose exactly which apps to
seal.
- Lock-screen word widgets: a rotating hanzi with pinyin and meaning, all day.
- Seal your apps: put TikTok, Instagram, or anything you pick behind a quick
vocabulary check.
- Earn scroll time: answer correctly to unlock, and watch minutes add up in your
ledger.
- HSK-graded words with tone-marked pinyin.
Built calm and honest:
- No account, no sign-up. Your progress lives on your device.
- No fake streaks or guilt-trips.
- You are always in control of which apps are sealed, and you can unseal anytime.
Continue after onboarding with a Lock In Pro subscription or a 30-day pass.
Subscriptions renew automatically until canceled. The 30-day pass provides full
access with one payment and does not renew automatically. Available plans and
prices appear in the app. Everything you seal and learn stays private to you.
