The Delphin can hold a variety of apps on the device. It comes pre-loaded with some you may need, but if you would like to install additional apps, you’ll need to do that seperately using the "Get Apps" app. To see a more detailed account of what it’s like to use various popular apps on the Delphin, click here to visit our Delphin Apps blog article.
