I saw this on Twitter and thought it might be of interest to the folks on here. Here's a link with more information: http://www.britishfencing.com/events/fie_international_fencing_rules/ I've got it on my phone and it's exactly what it says it is: a rules app. I quite like the way the penalties cross reference the rules. Could be very handy for people who are interested in learning the rules. Check it out. If you've got feedback I am sure British Fencing would like to hear from you.
