Pay for what actually keeps you safe.

Yes. Once you've downloaded a region, the charts and the routing engine run entirely on-device — a memory-mapped binary depth grid means no network calls during a passage. Jules defaults to cloud Gemini for conversations; on iOS 26+ Apple Intelligence devices Jules can run on-device instead.

iPhone and iPad on iOS 16.4 or later. On-device Jules (Apple Intelligence) requires an Apple-Intelligence-capable device on iOS 26+. Everything else — routing, anchor watch, Voyage mode, cloud AI — runs on any supported iPhone.

Fifteen today: the four US coasts plus US inland waterways, the Western and Central Mediterranean, Black Sea, Aegean & East Mediterranean, British Isles & Channel, Baltic, Norway (south-west and north-west), and the Caribbean — plus a free world-coastline baseline. Coastal waters use S-57 ENC survey data where available (1–5 m accuracy); deeper water uses EMODnet and GEBCO. New regions roll out on request — email us if yours isn't listed.

The planner uses your vessel's draft and a safety margin to rule out cells that are too shallow. Four risk presets (Conservative, Balanced, Aggressive, Shortest) let you trade clearance against distance. A three-level relaxation cascade guarantees dock-to-dock completion even when the start or end is inside a shallow harbour — but the cascade is transparent, so you always know which level produced the route.

No. AnchorQueen runs standalone on your iPhone's GPS. NMEA 0183 WiFi support and AIS integration are on the near-term roadmap — when they ship, you'll be able to plug into an existing on-board network, not that you need to.

Jules is a single conversational co-captain with access to your live vessel context — position, wind, tide, depth, anchor state — plus thirteen data tools to call: weather, tides, depth soundings, anchorage scoring, route planning, nearby vessels and more. You ask in natural language or tap a suggested chip; Jules answers in your device's language, streaming a reply in under a second.

The Basic (Free) tier gives you the anchor-watch engine and standard weather — enough to keep a simple anchorage safe. Jules and richer features (Pro Plan) start at $6.99/month, with a 1-month free trial. See the pricing page for the full breakdown.

You keep using the free tier indefinitely — your anchor watch, your history, your anchorages. Paid features remain active until the end of your billing period, then revert. All your data stays on device and in your cloud account regardless.

No. Early supporters who bought a previous paid version of the app get a complimentary 1-Year Pro Plan on us. You'll see the claim option inside the app once signed in.

Your live position is used to give the AI crew context (weather for your anchorage, not a generic one) and — if you opt in — to power the Social Radar showing nearby vessels. You can turn the Social Radar off and still use everything else. We never sell telemetry, ever.
