Read Aloud Books, PDFs & Text Books where every character has their own voice. Narrable is an audiobook app with a catalogue of full-cast recordings, and it will read your own books too. Open Discover and start listening, or bring an EPUB or PDF and have it voiced. A full cast, not one voice Most audiobooks are one narrator doing everybody. Narrable gives each character their own voice, so dialogue sounds like people talking to each other rather than one person reading both halves. And you choose. Every book is made both ways, so you can switch between the full cast and a single narrator while you listen, mid-sentence, and it picks up exactly where you were. Your own books Import an EPUB or a PDF and Narrable reads who speaks in it, gives each character a voice, and plays you a scene before it makes the rest. Your files stay private to you. While you listen Text highlights in time with the audio, so you can follow along or put the phone down. Speed from 0.5x to 2x with the pitch held, so voices keep their character. Tap any word to start there, skip, rewind, and pick up where you left off. Books download to the phone, so listening doesn't need a connection. Over a thousand voices. Nothing is recorded in a studio, and nothing is read by a person.

Compatibility ReadPDB currently supports compatible, non-DRM iSilo 3 documents and PalmDOC-family documents (including TealDoc and AportisDoc). The .pdb extension was shared by many Palm OS applications, so other .pdb files may use formats that ReadPDB cannot open. The following are not currently supported: • Password- or registration-protected books • MOBI and other Palm Database variants • Damaged or corrupted files • Unrelated files that also use the .pdb extension • PDF documents • Embedded images within documents ReadPDB does not include, sell, or download books. Import only documents that you own or have permission to use.

Verdict
The clearest difference is in-app purchases: ReadPDB at none against Narrable's 4. ReadPDB also leads on update cadence (daily vs every 5 days). On price, ads, device support and iOS requirement there is nothing between them.
