The Women’s Flat Track Derby Association (WFTDA) has updated it’s iOS app available for iPhone and iPad but has also released an Android version (finally!) which can be downloaded for $4.99 through the Google Play store.

Both iOS and Android versions include the ruleset as of March 1st, 2014 and include new features such as rules publications, Q&A’s, referee hand signals, minimum skill requirements, and for officials it has standard practices and verbal cues.

You can grab the iOS version through the Apple App Store or the Android version through Google Play. Both will run you $4.99.

A nice handy tool to have not only for skaters, refs, and volunteers but for you as the fan as well!
