5/5Invaluable for boating!
I've used this app for almost 3 years now and rely on it so much I feel guilty I've never provided a review. I use this mainly for boating in the Upper Chesapeake. Power boating, not sail boating. In the upper bay both wind direction and wind speed play a role in how rough the water will be and I can use this app to show me when the tucking into a certain section of the bay or scooting into the Susquehanna River will find more protected waters at a given time.

5/5First app I check
This app gives so much info with a very simple display. This is the first app I check when deciding when to take the boat out. While I am on the water I make it part of my routine to check the app to see what to expect in the following hours and days. This is one of my must have apps to go sailing with.

5/5I am a sailor, this app really works for me
Spend a little time learning the features and this app will become your first choice for passage planning. You will find that you can minimize the download file size by selecting the area you are interested in, the parameters you want to see, and the number of days that are of interest.

5/5Really good, easy to use app.
I have used this app for years. When I think about a passage I go here to check the conditions I will encounter. Easy to use. High on my list of really good apps.

5/5Simple and accurate
While other apps may be more graphic and engaging, I like the simplicity of PocketGrib. Nothing tricky...just the data I need.
