Surf Conditions App for Phones

Swellnet is awesome for checking out the surf conditions live on the PC, but is there a good app for the phone that can show you the surf conditions?

I am particularly interested in SA as that's where I live.

Surfstich which uses coastal watch cameras

willyweather. I have not used the app, but the Web-based version allows you to overlay tide, swell, temperature (and maybe other parameters).
