Learn Chinese: Lock In Hanzi

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.
