EarPal is the private interpreter for the world around you. Just tap Listen and EarPal hears the conversation, identifies each voice, and shows you a live translation in your language. Open the camera and EarPal reads any text it sees and translates it in place — menus, signs, packaging, screenshots from your library. No buttons to push, no turn-taking, no recording — just understanding. EVERYTHING ON-DEVICE Audio, photos, and recognised text never leave your iPhone. EarPal uses Apple's on-device speech, vision, and translation models, plus a state-of-the-art on-device speaker recognition engine. No cloud. No ads. No tracking. MULTI-SPEAKER, COLOR-CODED EarPal can follow several people at once. Each voice gets its own color in text mode — or its own distinct synthetic voice when you're listening through AirPods. Finally, you can sit at a dinner table with locals and follow the actual conversation. CAMERA TRANSLATION Point your camera at any text and watch translations land over each block in real time. Snap a still photo or pick from your library to translate menus, signs, screenshots, forwarded messages — all on-device. TWO LISTENING MODES - ACCURATE: waits for the speaker to finish their sentence, then shows a polished translation - LIVE: streams a rolling translation as words arrive, like live subtitles 30+ LANGUAGES Spanish, French, German, Italian, Portuguese, Dutch, Polish, Russian, Ukrainian, Turkish, Czech, Slovak, Croatian, Hungarian, Romanian, Catalan, Greek, Hebrew, Mandarin, Cantonese, Japanese, Korean, Vietnamese, Thai, Indonesian, Malay, Filipino, Arabic, Hindi, Finnish, Danish, Norwegian, Swedish, and English (multiple variants). ACCESSIBILITY Live captions of conversations, color-coded by speaker, in your own language. Built for travelers, language learners, mixed-language families, and deaf or hard-of-hearing users.

Manage anytime in Settings → Apple ID → Subscriptions. PRIVACY PROMISE EarPal does not collect or upload your audio, photos, or transcripts. Speech recognition, speaker identification, OCR, and translation all happen on your iPhone. Built by a solo iOS developer who got tired of translation apps that either spy on you, lock everything behind a $9.99/week subscription, or both.
