Discovr

Discovr are a series of apps for the Apple iPad by Jammbox which are characterized by using nodes to represent relationships between media. As of June 2011, there are two apps, for browsing music and apps.

The key advantage is that it is a tactile and visual way to see how items relate. The interface was described by the WSJ as "beautiful and dynamic," by Fox News as "easy and fun... an interactive map... an incredibly user friendly interface" ^[1]

In October 2011, Dicovr has announced that the apps has passed the one million downloads and $1.1 million revenue.^[2]

Operation

The user interface is based on radial layouts where a node is connection to 1-6 other nodes. It displays an interactive, graphic map. The user begins by searching or browsing a pre-selected set of recommended items. Tapping causes a node to expand, to display related items. Double-tapping takes the user to a page of content about the artist or app. ^[3] The interface uses a Force-based algorithm which causes the new child nodes to pop out of the parent node, repelling nearby nodes, and quickly settle into positions that minimize overlap. The graph algorithm was developed by Tamas Nepusz a PhD in graph theory that previously worked at Last.fm as a research engineer.^[4]
