Learn Spanish from the videos you'd watch anyway. Reelang turns real Spanish video — the clips native speakers actually post — into daily practice. No cartoon mascots, no fill-in-the-blank drills. Just a feed you scroll, with the language doing the teaching. How it works • Real Spanish videos, made for Spanish speakers, not for textbooks. • Hear real Spanish from across the Spanish-speaking world: Mexican, Peninsular, Rioplatense, Colombian, Caribbean, Andean, Chilean and Venezuelan. Set the feed to one, several, or leave it open. • A feed graded two ways: by your level, and by how fast people actually speak. Clear, slower speech to begin with, full native pace when you're ready. • Smart Subtitles underline the words worth learning — the most common 500, 1,000 and 2,000 words in Spanish — so you can see at a glance which word is worth a tap. • Tap any word in the captions to see what it means, right there in the sentence. • Learner insights: each clip comes with a short note on the Spanish worth knowing in it. Focus mode, the guided way in Do not just watch a clip, work it. Focus plays it once with no text, asks how much you caught, then takes it sentence by sentence and word by word until it lands. Tap a word to keep it for review. Prefer to just watch? Flow does that instead. Start at the beginning and the feed meets you there. As you get comfortable, it moves up with you. You're not memorizing lists. You're hearing Spanish the way it's really spoken — fast, casual, alive — and understanding a bit more each day. That's when it stops feeling like homework. Free to start. Scroll, tap, learn. — — — REELANG+ (OPTIONAL) Reelang is free to use.
