## Sandbook Description
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.

NATURAL VOICES, OFFLINE
- 41 voices in American and British English, Spanish, French, Italian, Brazilian Portuguese and Hindi
- A book in Spanish, French, Italian, Portuguese or Hindi opens with a voice in its language
- Powered by the open-source Kokoro model, running locally; no internet connection needed
- Follow along as each spoken word is highlighted
- Speed from 0.5x to 2.5x; each book remembers its voice and speed

READ ALMOST ANYTHING
- Import EPUB, PDF, Word (.docx), TXT, RTF, Markdown and HTML files
- Add a web page by pasting a link, or share it from Safari
- Scan printed pages with the camera, or pick a photo, and listen
- Send files or selected text from any app with the share sheet, or type and paste your own
- Open a document straight from the Files app with Open With, or set Sandbook as its default app

LISTEN THE WAY YOU READ
- Opens at the paragraph where you stopped
- In a PDF, the sentence being read is highlighted on the page; tap any sentence to read from there
- Reading options: light, sepia and dark themes, fonts, text size and line spacing
- Appearance: light, dark or matching your system
- See each book's length, listening time and the time left in the chapter
- Prepare a chapter's audio ahead of time, then keep listening with the screen locked; prepared chapters replay instantly
- Continue Reading with Siri or the Shortcuts app
- Export any text as an M4A audio file

ACCESSIBILITY
- VoiceOver, Voice Control, Switch Control, larger text and contrast improvements
- The app is available in English, Spanish, French, Italian, Portuguese (Brazil) and Hindi

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.

## Sandbook Reviews in United States

### *---- "Nope"
Doesn’t matter work at all
-- Makaana50, 2025-09-07

### ***** "Amazing!"
Would be great if it had a web app so it can also be used on desktop, but the ios app is great
-- MalloryKnoxxxx, 2025-07-29

### ****- "A Pretty nice app with lots of potential!"
Really love what Sandbook is doing — the text-to-speech feature is super useful and the overall design is clean and easy to use. It’s been helping me a lot!

One small issue though: the voice tends to pause awkwardly at the end of each line, which makes the listening experience feel a bit unnatural and annoying. It would be awesome if this could be improved in future updates.

Keep up the great work!
-- Fatima.iD, 2025-06-05

### ***** "Wow! Love love love this app!"
Amazing! The offline reader, uses a lot of VRAM… But sounds AMAZING! I was listening to a book that Gregory Keyes wrote: Elder Scrolls… and the language that Keyes uses for the many races, are VERY hard to read, yet this reader does very well! Anytime a reader can interpret and read Sci-Fi and Fantasy, it is a GOOD reader!!!’ 

I did notice that words like (Face, Gaze, Chase, Slate, space…) almost anything with a long A (Drape, table, take) almost has a “double syllable” sound… like there are 2 A’s … other than that…. Amazing
-- Thirdnail, 2025-05-21

### ***** "A TTS App with a voice that actually sounds human"
The voice sounds way more natural than other app I've tried - actually sounds like a person reading to me instead of a robot  Makes getting through my books so much easier when I'm tired after work.

Not perfect though. The app random stops reading when my screen turns off(super annoying when I'm trying to chores while listening). Also noticed the text highlighting gets wonky when switching chapters.

Still worth the download for sure. Hoping they'll keep polishingit with updates.
