Resona turns personal books and documents into an audio-supported reading experience. Import an EPUB or PDF, paste text, or scan printed pages with OCR, then listen to an on-device voice while the app highlights the current sentence and word. A Diary Mode offers a different visual presentation with animated handwriting, and voice and playback controls can be adjusted for a more comfortable pace. iCloud can sync books, reading position, playback position, and the selected voice across supported Apple devices. The app also provides access to public-domain classics from Project Gutenberg. The developer says narration stays on-device and that Resona has no account requirement, ads, analytics, or tracking. It does not provide a general commercial ebook catalog; users can bring their own documents or browse the listed public-domain collection. Current pricing is not specified in the description.
