Use it every day!

Keith Briley

Use it daily for our landscape photography business. Comes in super handy when certain locations can’t be safely visited when the tide is high. Allows us to plan hours and days ahead of time.

Works sometimes


Took a while to get it off California location. Then i turned on the alert. Got tired of them turned it off but even though its of still getting alerts.

Great app

Eric O.O.

The app is very easy. I love the alerts that are settable. It's also another way to remind me to get out on the water more often. Great job on the developers. I would recommend it for sure.
