Very cool, I've found out with my research a lot of people have mixed reviews ( everybody is a critic these days). I think its an awesome app. And proved to be a valuble tool just in the couple days that have down loaded it. On the negative side it is a battery murderer! And does take up some storage on the phone. I'm gonna put through a good test the next time I'm on the water. Can't beat it for 10 bucks!!!!
