Does anyone use a surfing app to document their surf session? I got the new Apple Watch (GPS & cellular) to be in communication (for emergency purposes only) while surfing. Pretty neat device as it can send & receive text and phone calls while in the water. Works well either way for me. So since I'm wearing this gadget in the water, decided to looked for a surfing app. I found two apps., "Dawn Patrol" (free) & "Surf Track" ($0.99). I'm leaning towards Dawn Patrol cause it's free, but, has anyone tried these apps or know of any others?
