OndaHear

OndaHear is your private, on-device hearing assistant. Hear every word, speak across 19 languages, and keep your conversations completely off the cloud.

WHAT IT DOES

LISTEN MODE

Real-time amplification with live captions. Boost soft voices, control background noise, and read what's being said as it happens.

LIVE TRANSLATION

Speak in any of 19 supported languages and read or hear it instantly in yours. Fully on-device — no servers, works offline after initial language download.

VOICE CONVERSATION

Pair with another device for a two-way captioned dialogue. Each person speaks in their preferred language and reads the other side translated live.

TEXT CHAT

Talk and your message is delivered aloud on the other phone, translated automatically. Perfect when speaking openly isn't an option.

HEARING TEST

Built-in audiogram across 6 frequencies. Get a personal hearing profile and apply audio settings tuned to your ears.

APPLE WATCH

Read live captions right on your wrist. Start, stop, and boost from there too — without reaching for your phone.

EXTERNAL MIC: THE BIGGEST UPGRADE

Captions are only as good as the audio that reaches them. Clip a small wireless mic on the person you are talking with, or set one beside the TV, and keep your phone with you. Voices arrive clean instead of competing with the room, and captions get far more accurate across distance and background noise.

The built-in Hardware Guide lists microphones tested with OndaHear.

PRIVACY-FIRST DESIGN

Most hearing apps send your voice to the cloud. OndaHear doesn't. Speech recognition, translation, and audio processing all run entirely on your iPhone, using Apple's on-device frameworks. The app even works in airplane mode.
