Nick Locking, an enterprising individual, created a portable application for generating statistics on random dice rolls to wound in Warhammer 40K. From the iTunes store… “Just enter the relevant statistics and the app does the rest – showing you ‘Average Wounds’. Advanced mode includes things like re-rolls, Rending and Feel No Pain.”
It’s limited in the capabilities right now. But it is mentioned that future editions will include shooting versus vehicles and close combat.
i40k is $5.99 and available now on iTunes.
