Was looking at the watches but curious what apps there are for your phone. Im guessing the benefit to the watch is its on your wrist. Waterproof. 2 thing my phone is not. But since they use your phone as a link you still need it on the boat. So starting just looking at apps. Id like distance top speed and average speed and the little tracker on the map. So whos using what? Im still back and forth between the watch and not. So just looking for info.
