The best surf apps, like Surfline's iPhone workhorse, mash together buoy data, tidal charts, and weather forecasts to give you not just a listing of surf spots but also a good idea of when they'll be breaking best. (Inferior ones rely solely on tidal charts.) Skullcandy's Android app is slightly less detailed, but since the data comes from Surfline, it's reliable. Both free.
