Your apps are held hostage. Glosso holds the keys. Feed him few minutes of words in 9 languages. He grows. Instagram unlocks. You earned it. WHO IS GLOSSO? Glosso is a small creature who lives on your phone and eats words for a living. He owns a cowboy hat. Sometimes a crown. He has moods. He has a pantry. He has a strong opinion about how much you scroll. HOW IT WORKS 1. You pick the apps Glosso guards: Instagram, TikTok, X, YouTube, Reddit, whatever is eating your day. 2. You tap one of them. iOS Screen Time hands the keys to Glosso. 3. Glosso makes you match words in the language you're learning,from 1 to 15 minutes, English paired to Japanese, French paired to Korean, your call. 4. You finish. Your apps open. Glosso eats. The word goes in his pantry. 5. Repeat tomorrow. He grows: baby, teen, adult, legend. WHY IT WORKS Other blockers fight you. You uninstall them by Friday. Glosso doesn't fight you he just won't open the door until you've done the thing. And the thing is fun. Word-matching is the only "productive" task your brain accepts when it is already begging for dopamine. The trick: by the time you finish few minutes of vocabulary, the urge to scroll has quietly died. You either open Instagram and bounce, or you don't bother. Either way, the pantry got fuller. WHAT YOU GET • 4 growth stages: baby, teen, adult, legend • 47+ unlockable cosmetics: hats, forms, moods, seasonal drops and we keep on adding more • 8 signature colors assigned from your first name, no two friends get the same Glosso • A pantry that remembers every word you have ever fed him • Streaks, stats, a progress bar that actually means something • SRS method (the same spacing that powers Anki and Babbel) words stick 9 LANGUAGES, DAY ONE English, French, Spanish, Italian, German, Portuguese, Arabic, Japanese, Korean. Learn Japanese through English, Korean through French , whatever combination your brain wants. No paywalled language packs. All nine included from the first tap. PRIVACY Glosso runs on Apple's Screen Time API, the same framework iOS uses for its own parental controls. No VPN. No profile to install. No passcode backdoor. Your app data never leaves the device. Feed him words. Starve the scroll. Made in Paris. No investors. No tracking.
