Before you purchase this app, you might want to try the free version which is fully functional but with some limitations.

Important note:
Grib files are computer-generated forecast files which are sent without review, and are offered on an as-is basis. There is no assurance that the data is accurate or correct. By using such data, you acknowledge and agree to these limitations.
The weather routing module is for planning purpose only.
The maps used either in navigation or by the weather routing algorithm might be very coarse and for example might not include all the islands.
The Location used by the navigation module might be inaccurate.
By using these maps, these data and this algorithm you agree to these limitations and assume all the responsibility for their use.
