If you've been keeping up with us, you are already aware of our recent update to our Android, iOS, and OS X development libraries (if not, go read it!). Shortly after that release, our developers have been rolling out updates to all of our mobile demo apps available on the App Store, Google Play, and Windows Store.
In addition to updating our existing demos, we plan on adding new demos for credit card and passport recognition, so keep a close eye on that page if those features are of particular interest to you. If you can't wait (and we don't blame you), the source code for those demos ships with the main evaluation for each platform.
