You know the words. Real speech still gets away from you. Sound familiar? Fast. Blurred together. Half the sounds gone. PlayLingo turns any YouTube video into practice: understand every line, then say it yourself. Subtitles, translation, explanations, shadowing and word review. WHO IT'S FOR • You read English fine, but listening is the one skill that won't move • You want to keep up shadowing but quit after three days • You want to follow your favorite YouTubers, shows and interviews without pausing for a dictionary • You learn a language other than English: same app, same method WATCH: any video becomes your material • Any YouTube video. Plus curated picks refreshed every day • Collections by level, A1 to C2, and by topic. Shelves like "Start here" and "6 minutes or less" UNDERSTAND: one sentence at a time, never left behind • Subtitles split by sentence and synced with the video • Phonetic transcription, so you see how a word actually sounds • Parts of speech in color, so the shape of a sentence is visible at a glance • Translation in context: what the line means in this scene • Tap a word or an idiom and Lingo, your assistant, explains it in this sentence. "Make sure" is explained as one phrase, not two words PRACTICE: five ways to watch the same video • Watch: subtitles and translation on, follow along • Understand: translation hidden, work out the meaning yourself • Listen: text hidden, catch the line by ear. Tap only the word you missed • Build: put the line back together from its words • Speak: say each line out loud. Words light up as you say them • Even videos in your own language work: you study their translation into the language you're learning REMEMBER: words come back before you forget them • Save words and phrases straight from the subtitles • Review runs on FSRS, a spaced-repetition algorithm timed to your memory • Every card keeps the scene and the sentence where you heard the word • A Home Screen widget with your word of the day KEEP GOING • Three minutes of watching or one round of practice counts as a study day • Your streak comes with freezes that cover a missed day on their own • Sign in with Apple and your words and progress sync across iPhone and iPad FREE AND PRO • Free every day: subtitles, translation, Lingo's explanations, daily practice and word review • No limit on which videos you can open. Any YouTube video • The free plan limits only daily watch time and how much you practice. Pro removes those limits • Cancel anytime in the App Store WHAT PEOPLE SAY (App Store reviews) "For the first time, I actually enjoy learning English." "The only app I use to watch English videos.
