Nauticare is one product that you can reach in three ways.
The cloud app, in a browser
The cloud app is the one you reach in a web browser, from anywhere with an internet connection. Every yacht is in it, and it is what most of this help describes.
The cloud app, on your phone
The Nauticare app for iPhone and Android is the same cloud app on your phone: the same sign-in, the same pages and the same permissions, with push notifications added. It always connects to the cloud. See the Nauticare on Your Phone section.
The on-board app
Some yachts also run the on-board app, installed aboard the yacht and reached in a browser over the yacht's own network. It keeps working with no internet and syncs with the cloud whenever a connection is available. It shows a Local badge in the header, which is the quickest way to tell it apart from the cloud app.
A yacht that runs it is called vessel-managed. A yacht that does not is cloud-only, which is the default. See the On-board App section for what crew see aboard and how syncing works.
What office staff notice
On a vessel-managed yacht, Maintenance, Tasks and Inventory are read-only in the cloud. The records are all there to view, but the buttons that would change them are hidden, whatever your permissions, because those edits are made aboard and sync back. The Connectors tab in Vessel Settings is read-only too, because connectors are set up aboard. Everything else is edited in the cloud as usual. The same read-only period applies while the on-board app is being installed and while it is being decommissioned, and a banner at the top of the yacht's pages says so. Once the yacht is vessel-managed, a sync indicator in the same place shows whether it is online and in sync.
