Bill's Crew Manager software is compared to using free generic software tools to communicate with your crew as you organize events, compared to the free, basic, premium, and ultra versions of the popular TeamSnap software used to powerfully manage team sports, very popular with kids soccer teams across the US. Bill's software smoked even the Ultra version of TeamSnap, which I previously used for my 109 team. Bill's software earned 38 feature points, just completely smoking the 17 points earned by 2nd place TeamSnap Ultra and less than 12 for the two free products. Focused on just big key features for the team leader, Bill's software earned 5 points vs. 3 for Ultra, and 1 for the free tools.
Since then Bill's software has gained a bunch more features in the pursuit of getting crew to be on the same page with the owner.
