What's New in OndaHear

2.2.9

September 9, 2026

Live Translation: Lecture Mode Lecture Mode is built for one person speaking for a long stretch: a class, a talk, a service, or a guided tour. Connect an external microphone, tap Lecture Mode on the Live Translation screen, and captions keep up continuously instead of waiting for pauses. Add earbuds and the translation is also read aloud to you while the speaker talks. Better with external microphones • Live Translation now works correctly with USB-C and wireless microphones • Your audio output stays where you put it. Connecting a microphone no longer forces sound to the phone speaker • The microphone in use is shown on screen • Quiet microphones are boosted so speech is recognized more reliably Faster captions • Lines appear shortly after the speaker stops, instead of waiting for a long pause • Short replies such as "No" are captured instead of being dropped Saved transcripts • Play a saved transcript back, read aloud in the language it was saved in • Show both languages or only one, with a clearer language selector • Fixed transcripts that saved empty or were missing lines • Better contrast on the buttons in the save and transcript views Reliability • Speech recognition now recovers on its own if it stops during a long session • If a language's speech model is not installed, the app says so instead of retrying silently • Various bug fixes and stability improvements Everything continues to run entirely on your device. Once your languages are downloaded, captions and translation work with no network connection.

User reviews

Easy, personalizable, and *actually* private

This is exactly what I’ve been looking for! I always worry about using apps that “listen” to you because I never know if my information is as protected as it should be, but with OndaHear, my data never even leaves my device! That alone would make this my favorite hearing booster, but the features really tip this app over the edge. You can make different hearing profiles to tailor the sound exactly how you need it in different environments and the quality is AMAZING. I love that you can have multiple inputs so I’m not choosing between hearing the TV clearly and hearing what someone in the room is saying. And captioning a live convo is a GAME-CHANGER for when my brain just won’t process what someone is saying. Can’t recommend this enough!

Response from developer

This honestly made my day. The privacy part wasn't a marketing decision — I'm hard of hearing myself and I didn't want my own conversations leaving my phone, so everything stays on-device. And you nailed why the multiple inputs and hearing profiles exist: real life isn't one listening environment. Thank you for taking the time to write this out.

Hear it all!

Excellent hearing and caption app. Easy to use, accurate captions, and great privacy. OndaHear has become part of my daily routine. The translate function is very easy to use for those times language is a barrier.

Response from developer

Thank you — "part of my daily routine" is exactly what I hoped for when I built this. Really glad the translation feature is helping when language gets in the way. I'm HoH myself, so hearing it's working for you means a lot.

Easy to use

This is so easy to use and absolutely fantastic.

Response from developer

Thank you so much — "easy to use" is the highest compliment for an app like this. Appreciate you giving it a try!
