Heard for iOS Launches ePub Reader with On‑Device Text‑to‑Speech

Heard for iOS is a newly announced ePub reader app. The app includes built‑in text‑to‑speech functionality. Speech synthesis runs entirely on the device, avoiding cloud processing. Users can listen to ePub content without an internet connection. The on‑device TTS aims to preserve privacy and reduce latency. Heard targets readers who prefer auditory consumption of books. The app’s design integrates reading and listening in a single interface. The project is shared on Hacker News for community feedback and testing.
