BlueBook is an app which is designed to organize your books the easy way. Scan the book barcode using the rear camera on your iPhone and it will fetch the book details from ISBNdb.
The book data is stored locally using Cloudant Sync (CDTDatastore). Thus, the app can be used even when offline. To make the app truly cross-platform, the data gets synced with a Cloudant NoSQL database in the IBM Cloud.
