Sandbook: Natural Voice Reader

Sandbook reads books, documents and articles aloud in natural voices, entirely on your iPhone or iPad. Nothing you read is uploaded, and there is no account, no subscription and no ads.

PRIVATE BY DESIGN
Your books, text and voices stay on your device. Sandbook never sends what you read to a server.

GOOD TO KNOW
- Voices require iPhone 12 or later, or an iPad with an A14 or M1 chip or later. Sandbook also needs iOS 18.2 or later.
- Real-time reading pauses when the screen locks. To listen with the screen off, prepare the chapter first.
