I just inherited a Golf Group of about 20-30 guys. The previous team leader used a tool by Eagle Golf called Mulligan. It looked like an excellent tool for small groups, however it only works on Mac. I need one for Windows platform.

I saw in a recent post some guys are using:

18 Birdies, Grint, Golfshot Pro, Swing U

which is best for small groups with the least expense?

Thanks! Rob
