Three modes
One app, every way you need to translate.
Start with the livestream. Keep it for menus, meetings and the train station.
Screen
Read anything on your screen.
Bubble messages, fan-cafe posts, menus and PDFs — captured through Screen Broadcast and translated live.
Around Me
Turn the room into subtitles.
Point your iPhone at the conversation. Echo captions nearby speech through the microphone — concerts, cafés, meetings, family dinners.
Why Echo
Idol names. Not lost in translation.
IU. SEVENTEEN. Stray Kids. Echo's K-pop glossary helps keep the names and fandom words you know recognizable, even when the conversation moves fast.

A real person answers
Some lines are worth keeping.
Does Echo work offline?
Partly. When your device and language pair support Apple's on-device speech and translation models, Echo works without a connection. Otherwise it uses Microsoft Azure AI Speech & Translator and needs internet.
Which languages does Echo support?
Echo translates Korean, English, Simplified Chinese (简体中文) and Traditional Chinese (繁體中文). The app interface is available in English, 简体中文 and 繁體中文.
Do you record my audio?
Echo processes audio to produce captions. On-device processing stays on your phone; when cloud translation is required, the transcript is sent to Microsoft Azure AI Speech & Translator only to return the translation. Translation history is saved locally on your device and you can delete it in the app.
What happens when my free minutes run out?
Translation pauses until your daily 5 minutes reset. You can keep using the app, upgrade to Echo Plus, or buy a Day Pass for 90 minutes valid 24 hours.
How do I cancel?
Open Settings › Apple ID › Subscriptions on your iPhone and cancel Echo Plus there. Cancel at least 24 hours before the period ends to avoid the next charge. The Day Pass is a one-time purchase, so there is nothing to cancel.
Can I caption a Weverse or YouTube livestream?
Yes — Audio mode uses iOS Screen Broadcast to capture the app audio you choose, and shows captions in a floating overlay. Some apps and protected media may block, mute or restrict capture; Echo does not bypass those protections.
Which devices does Echo run on?
iPhone and iPad on iOS 26 or later. Screen mode, Audio mode and the picture-in-picture overlay require a physical device.
Don't wait for the fansubs.
