SporeBrowser is a Sporepedia browser for your iPhone or iPod Touch.
The Sporepedia is the online database of player-made creations from the game Spore, made by Maxis and Electronic Arts.
You can browse the all-time top rated creations, today’s coolest creations, a selection of random creations, and more. Just choose which category from the tabs on the bottom of the screen to see the first ten in that category. To see more, scroll to the bottom and touch the “load more” button. To see more information on a certain creation, touch it once. Here you can see a larger picture, the full title, the full description (if it has one), more creations from the author, the birth date, the user rating, and tags.
