Superb App

CarkusM

Really very easy to use. Stores grab files so you can refer back when offline offshore. I have used for years and will continue to do so.

The best

This is by far the best Grip app.
It's ease of use.
It's clarity.
It's presentation.
Downloads fast when at sea.
So many features, you have control over everything.

Simply brilliant! Thank you.

Was told about this app by a friend just before taking my new boat on a maiden voyage from l'Aber Benoit through the Chenal du Four and on to Douarnenez. Finding a favourable weather window was absolutely essential and this app enabled us to do this. Simplicity itself to set up and use. The one small problem I encountered was sorted out very quickly by re-installing the app. Backup is excellent - I e-mailed for advice and received a very helpful and friendly reply within 24 hours.

I have been using it for about ten days now and the accuracy of prediction has been very impressive over three days and reasonably good over five. You can show as little or as much data on a chart as you want. I particularly like the the ability to show wind direction and wave direction at the same time as these are not always the same and for anyone sailing being able to see when there are differences and what these are is very helpful. It also gives very good predictions for height of swell, also extremely useful.

Anyone who sails will find this app indispensable - far superior to wind guru and well worth spending the very reasonable £3 odd charged. Wouldn't be without it.
