How is this app free!

Holy hunters app! This is amazingly accurate, and has every option I want in an app. At our deer camp we have 10 guys and 20+ stand locations. Hard to keep track of everyones location let alone get to someone who shot a deer after dark. With this app we can send gps coordinates, track stand locations, have accurate yardage between locations so we can best plan our way around. Again how is this free!?!?! Thank you guys for creating this for us. A lifesaver!
