Show HN: I built an iOS app that turns EPUBs into audiobooks

I had a bunch of ebooks with no audiobook version available. So I built an iOS app that converts EPUB files into audiobooks using text-to-speech.

Two voice options: - Free on-device voices (processed locally, no server needed) - Natural cloud voices (one-time purchase per book, no subscription)

Cloud conversion runs chunk by chunk. You can start listening other chapters generate in the background. Once done, the audiobook lives on your device.

No account required. No subscription. You import your own EPUBs and either use device TTS for free or pay per book for the cloud voices.

Nothing stored on backend, neither books or audio files.
