The Home screen
Everything in Nexus starts from the Home screen: twelve tiles, each with its name underneath. Tap a tile to open it. The back arrow at the top left of every screen (Back on an iPhone or iPad) takes you back.
- Chart: where you are, the boats around you, and the routes you plan and follow.
- Anchor: set the anchor alarm and watch the boat swing.
- Dashboard: your instruments, laid out as you like them.
- Alerts: what the boat is warning you about, and which alarms you want.
- MOB: man overboard. The tile with the red ring, so you can find it without reading.
- Book: the ship's log, the boat's equipment, and the work it needs.
- Weather and Tides: the forecast and the tide where the boat is.
- HUD: the one screen to keep open under way.
- Bluetooth: sensors the boat reads over Bluetooth.
- Radar: the boat's radar, if it has one Nexus can read.
- Settings: your boats and account, units, light or dark, and Diagnostics if something seems wrong.
Warning: When someone is overboard, every phone aboard switches to the man overboard screen, and the MOB tile turns solid red and pulses. See Man overboard.
At the top right of every other screen you'll find the lifebuoy for man overboard, and a bell with a number when the boat has alerts. Tap the bell to open Alerts.
A phone always shows Nexus upright. A tablet can be turned sideways: Home then puts the logo beside the tiles.
Is the phone talking to the boat?
The small icon at the top of the screen shows how this phone reaches your boat: Direct on the boat's own Wi-Fi, Cloud over the internet, or a Wi-Fi with a line through it when it can't reach the boat at all. Before you rely on it explains each one.
When the app can't reach your boat, Home says so: "Can't reach" your boat "right now. It may be switched off or out of signal; the app reconnects when it answers." If the phone itself has no signal, it says "This phone is offline" instead. You don't need to do anything: Nexus reconnects by itself.
Tip: The screens behind the tiles show what the boat last told them. While the boat can't be reached, the numbers don't change, and the phone won't hear new alarms.
