Now on Mac

The chart table, on your Mac

The same AnchorQueen from the App Store runs natively on Apple Silicon Macs. Plan passages, study charts and brief with Jules on the big screen — then pick the route up on your iPhone at the helm.

One purchase, every screen — your subscription and chart regions from iPhone and iPad are already unlocked on Mac.
The full offline chart engine — vector charts, depth shading, routing and weather — renders natively on Apple Silicon.
Made for planning: trackpad chart navigation, a resizable window and room to work alongside your other tools.
Underway, the helm stays with iPhone and iPad — Macs carry no GPS receiver, so live anchor watch and navigation belong on board.

Boat integration

Your boat has a voice. AnchorQueen speaks it.

Connect to the Signal K server aboard and the app stops guessing: real wind, real depth, the ship's own GPS — streamed live into the chart, the HUD and the anchor watch on every device.

1
Found in seconds
The app scans your boat's Wi-Fi (mDNS/Bonjour) and lists every Signal K server aboard — no IP addresses to type.
2
One live stream
A WebSocket subscription delivers JSON deltas — depth, wind, heading, speed through water, sea temperature and position — straight from the masthead and the transducers.
3
AIS in the same breath
Vessels your server hears on AIS ride the same stream and appear on your chart next to your own radar picture.
4
Fails safe
Junk fixes are rejected at the door, and if the feed goes quiet for 30 seconds the anchor watch falls back to the phone's GPS — armed, always.

No Signal K aboard? AnchorQueen also speaks raw NMEA 0183 over your Wi-Fi gateway (TCP/UDP) and Bluetooth LE pods — and NMEA 2000 arrives through any 0183 gateway.

Built for iPhone, iPad and Mac

The whole helm in your pocket — anchor watch, charts, routing and Jules, on every screen.
