Customer Reviews

Great app to see the currents

Hope they add the data for the rest of the bay soon

Good app but crashes with 8.1.3

Crashes instantly during open with 8.1.3 (not sure about earlier IOS 8 versions). Probably just needs an update. It's a very nice free app and will change my rating if it will open with latest IOS.

Good Idea Bad App

It doesn't update consistently. It won't let you move to different area's of the bay. It gets stuck on one area. It won't let you move or delete a pin. Could be very useful if it worked well.
