Heard

Heard is an iPhone app that converts EPUB books into spoken audio using on-device text-to-speech, solving the problem of listening to personal ebooks without internet or server processing. It targets individual consumers who want to listen to their own DRM-free EPUBs or a curated library of public-domain classics, with a free tier and optional Pro subscription. The app differentiates by generating natural neural voices locally on the device, ensuring privacy and offline functionality, and includes features like automatic page turning and background playback.
