Live captions, floating over the app you are already watching. Echo listens to whatever is playing — a livestream, a video, the room around you — and floats the translated captions in a small window on top of it. Nothing gets covered. Nothing gets missed. THREE WAYS TO TRANSLATE • Live audio. Sound coming from any other app — Weverse, bubble, YouTube, Instagram, TikTok — translated as it plays. • On-screen text. Comments, chats, posts and menus, translated right where you are reading them. • Around me. Point your iPhone or iPad at a concert, a TV or a conversation and read along live. BUILT FOR THE HARDEST VERSION OF THIS Echo was built for K-pop fans, which is this problem with no margin for error: the live happens once, it is in Korean, and the names have to be right. • 300+ group names, member names and fandom terms, spelled the way fans actually write them. • 40+ languages, with the spoken language detected automatically. • Captions arrive while they are still talking, not after. • iPhone and iPad. On iPad, Home, history, sharing, setup and the plan screen are laid out for the bigger display. NEW: YOUR GROUPS IN ONE PLACE • The Feed. Lives, new videos, news and posts from the groups you follow, with the headlines translated into your language. Tap a video or a live and Echo translates it. A daily digest catches you up on what you missed. The Feed is rolling out gradually, so it may not appear for you right away. • Live alerts. Get a notification when a group you follow goes live, so you are there from the first word. KEEP EVERY MOMENT • Every session is saved and named for you, like "Friday night live". Free keeps your latest three; Echo Plus keeps them all, to reread, copy or share. • Turn the best lines into share cards. Five styles: a single quote, both languages together, or the conversation exactly as it was said. • A translation came out wrong? One tap tells us. We read every thumbs-down. QUIET BY DEFAULT • On-screen text can translate on device, where your iPhone or iPad supports it — faster, and it works offline. Live audio always needs a connection. • No sign-up, no account. Open it and go. • Echo is not a screen recorder. It uses only the audio or screen text you choose to translate, and never bypasses DRM or platform protections. FREE EVERY DAY Echo includes a free daily translation allowance. Two optional upgrades remove it. Echo Plus. Translate past the free daily allowance, up to a 5-hour daily fair-use limit set out in the Terms of Use. Your full session history instead of only the latest three, synced across your devices.
