You can download books to your Apple Watch if you have at least BookBeat 8.3 installed. Otherwise you have to update the app first.
This is how you download a book to your Apple Watch:
- Open the BookBeat app on the watch and go to "My Saved Books".
- You will now find a list of your books.
- Press the book you want to download and then "Download" under the cover. Wait until your download is finished.
You can only download one book at a time, so if you want to download more than one book, you will have to wait for your download to be finished before you can start a new one.
If you have a slightly older version of the BookBeat Watch app, you might instead find a menu point with the header "Download" in the main menu. In this case you tap this header. Here you will find a list of your recent books. Click the book you want to download and wait for the download to complete.
