You are not too old. The "critical period" is a myth: adult brains still rewire with intentional focus plus quality restful sleep. Synapse is a language learning app built on that science: train your ear first, make mistakes on purpose, and let each night of sleep lock in the day's practice. No streaks to protect, no guilt trips. STORY PODCASTS Follow a whole story in your new language on day 1. Short, immersive stories told slowly and clearly: read along word by word, tap anything to learn it instantly, and keep listening with the screen locked — a podcast that teaches. EAR TRAINING Hear the difference between words that used to sound identical. Your native language decides which sounds you can't hear yet; listening exercises built for your exact native/target pair train you to catch what native speakers hear effortlessly. Soundalike drills then tackle the words that trip learners up. ALPHABETS FROM ZERO Sound out real words in an alphabet that was pure noise to you last week. Letter-by-letter audio courses take you from zero, one sound at a time. (Rolling out language by language.) FLASHCARDS FROM YOUR LIFE Learn the words your own life is made of. Point your camera at anything with Language Lens and learn its name on the spot; spaced repetition then brings each word back right before you'd forget it, so it sticks for good. GRAMMAR YOU CAN SEE Say the right form without reciting a rule. Conjugations and cases as clear visual tables, linked to real example sentences — patterns instead of memorized rules. LEARN TOGETHER Trade your first real sentences with another person this week. Pair up with a partner and exchange short daily messages in each other's target language. Family kits (select language pairs) give parents and kids a shared track. 26 LANGUAGES Korean, Japanese, Spanish, French, Vietnamese, Russian, German, Italian, Portuguese, Arabic, Hindi and more — with the interface in your own language too. THE METHOD Free video lessons at synapseko.com explain the science behind it all. Your progress follows you to any device with a free account.
