Sync Your eBooks—The Kindle app lets you read the same book across devices and automatically syncs where you left off so you can start reading on one device and pick up where you left off on another device. The app syncs your furthest page read, bookmarks, notes, and highlights between Android, PC, Mac, iPad, iPhone, iPod touch, BlackBerry, Windows Phone 8, and any of our Kindle devices using our Whispersync technology.
