Parfaite pour les navigations hautiriere

Excellente application pour la navigation, notamment au large ! Le mode hors ligne est vraiment pratique pour limiter la consommation de données pendant les longues traversées. Je télécharge mes fichiers GRIB à l’avance et peux ensuite travailler tranquillement mes routages sans connexion. J’apprécie aussi beaucoup la compatibilité MBTiles, qui me permet d’utiliser mes propres cartes marines lors de mes navigations côtières. Une application très complète et parfaitement adaptée à une utilisation en mer
