I love this app but can't use it past two days as when I click on upgrade it shows premium and circles forever without showing me any option to purchase the upgrade. Edit: it was a problem with the latest updates of GooglePlay. It worked after uninstalling them. Love the app now and great/one of the only places to download 10 days ECMWF grib files.

Hi, this is most likely a network issue. Can you try on another network or restart your device?

Difficult to enter waypoint. Dragging is very sensitive. Better if you can enter the coordinates. Trying to plan a route in france but it keeps going back to My location in Naples fl. I MUST BE DOIN SOMETHING WRONG. I want to enter a starting and ending point in the Atlantic of the coast of france. Great responses from support. Almost there.

Edit : Please send the details to I do not have enough room here to reply in detail. You can edit any waypoint coordinates if you want to adjust them. Once a route is created or loaded: Long Press > Manage Routes > Edit route mode > Edit > Press a Waypoint and edit its coordinates.

The best weather routing app I found so far. User must keep in mind that this app calculates the route assuming he is a perfect sailor. As for me, reducing the sail area to 85% in polar calculator gives me somewhat accurate route timing results. What I would like to see in app in the future: - more options for the grib data, like gusts, waves, precipitation, currents - in planning mode would be nice to have a switch between wind/gusts, waves/currents - make animation smoother, less discrete.

Thanks, Polars are issued from VPP software and are always too optimistic. In average, we find that reducing the polar efficiency to 80% for light winds and 85% for stronger winds works quite well. Glad you found the same efficiencies. Many models are offered in our Premium option. Which model is missing? please contact us using the Contact us menu
