About this app
CatEar is a listening and speech training app for people with hearing loss, language learners, and anyone who wants to train their listening in a structured way.
It includes single-syllable word drills, noise-interference training, telephone-simulation exercises, and instrument timbre practice, plus hearing tests, noise measurement, and audiogram records. Your training history stays on your device.
A macOS version is now available, so you can use it on iPhone, iPad, and Mac.
Some speech synthesis and real-time conversation features use a cloud speech service. See the privacy policy for the details.
