Your scrolling habit is now your French habit. Lock the apps that eat your day — three words to open them. Real Screen Time locking. No guilt trips, no gimmicks. You open the same app 40 times a day. What if French opened first? LKIN stands between you and the apps that eat your day. Tap a locked app and LKIN asks for three French words first. Finish them — about 30 seconds — and everything unlocks. That's the whole idea. Your scrolling habit becomes your study habit. WHY THIS WORKS Most language apps lose you in a week, because they need you to remember they exist. LKIN doesn't. Your own reflex brings you back a dozen times a day, and every craving becomes a rep. THE LOCK IS REAL LKIN is built on Apple's Screen Time. Locked apps genuinely will not open until you have practiced. Not a reminder. Not a nudge. A lock. HOW IT WORKS • Pick the apps that steal your time • Tap one — LKIN's lock screen appears instead • Practice 3 French words or sentences, about 30 seconds • Everything unlocks for as long as you choose BUILT TO BE HONEST • One gentle nudge a day, at a time you pick. No guilt trips. • Take a break: pause every lock for 24 hours, one tap. • Break a streak and your history stays. The words you learned are still yours. • Export or delete your data whenever you want. REAL LEARNING, NOT TRIVIA • Spaced repetition brings each word back right before you would forget it • Words graduate into full sentences • French pronunciation on every card • Track every word from New to Mastered YOURS TO TUNE • 1 to 5 words per session • Unlock for 15 minutes, 30 minutes, an hour, or the rest of the day • Custom lock hours — weekdays only, evenings off, whatever fits • Light and dark, haptics, sounds, daily goals LKIN PRO Free forever: French, up to 3 locked apps, streaks, and daily practice. Pro adds unlimited locked apps, custom unlock windows, strict mode, streak freezes, and the full French library. Coming soon: Spanish, Japanese, German, Italian and Korean.
