I’ve been playing with @dawnpatrol.appwith— it and my phone it geolocates and measures the movement of my bodysurfing. They recommend using an Apple or surf watch but I use my phone. They discourage it but as I’ve been carrying my phone in the water for years I’m undeterred. With it plus a @surfline sub I can watch video of some of my rides. Fun.
