User Reviews
Been using it for years, love it.
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.
Not usable on Great Lakes.
Lots of useful info for the budding prognosticator/weather enthusiast.
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.
About the best long range weather forecast I’ve ever used I would say 90 percent accurate Forty plus years on the North Atlantic
While other apps may be more graphic and engaging, I like the simplicity of PocketGrib. Nothing tricky...just the data I need.
PocketGrib uses the GFS model (US source). Nothing fancy, quick to load, easy to interpret.
I use it for boating but it is useful for anyone that understands Grib files and wants to check the NOAA models.
Been using this for several years and have found it invaluable.
