But it is a mandatory component of the mapping application called:"Jeppesen Marine Plan2Nav" BE SURE you have already installed the Plan2Nav before installing this one.
This app is the bridge between the free Plan2Nav app and the Jeppesen Marine Web Store. Jeppesen is an internationally established company, it is also a Boeing owned company. Google Play is a good, but still a generic content store and Jeppesen decided to offer an extended level of service to its customers world wide to sell the maps and other services. We also believe in the importance of keeping your privacy or payment information secured.
