Jules — your AI co-captain — stands anchor watch all night, warns you before the wind shifts, and plans depth-safe passages and reports to Captain.
SafeAnchor.Net Anchor Watch re-created within Boating App. Presents best user experience with help of Jules. Drop the hook and sleep easy. Jules stands watch all night,
AnchorQueen is your intelligent co-captain: turn-by-turn coastal navigation, depth-safe routing, live AIS traffic, and Jules — an AI co-captain who answers in plain language and stands anchor watch while you sleep. One app, and it works fully offline.
NAVIGATE TURN BY TURN.
Steer a clear course to your next waypoint with live bearing, distance, speed over ground and cross-track error. Big, glanceable guidance that stays readable in the cockpit — day or night.
CHARTS WITH EVERY DETAIL.
Our own Nautica Day and Nautica Night S-52 IHO vector charts render every sounding, buoy, light and hazard. Six day/night depth palettes keep the picture clear from bright sun to a dark night passage.
DEPTH-SAFE PASSAGES IN SECONDS.
Long-press a destination and watch the route grow. Hybrid A*-APF routing finds a depth-safe passage in seconds — honoring your draft and your taste for risk, with four risk presets across four vessel profiles. Scrub the voyage from 1× to 256× over a live depth profile, then hit Start for live BRG / DIST / SOG / XTE alerts.
SEE EVERY VESSEL — LIVE AIS.
Real-time AIS traffic overlays your chart: who's around, where they're headed, how fast. AnchorQueen knows the COLREGS, too — it flags traffic separation schemes and warns you before a close encounter, not after.
WORKS WITHOUT SIGNAL.
Download a region once and the charts, routing grid, tides and bathymetry all work fully offline — 15 cruising regions from the U.S. coasts to the Aegean, Baltic and Caribbean, with EMODnet + GEBCO depth data.
MARINE WEATHER, SCORED FOR YOUR ANCHORAGE.
NOAA and Open-Meteo, blended and live. Wind and gusts, waves, a 7-day meteogram, and tide referenced to MLLW — for your exact spot, not a generic regional outlook. Backed by 8,000+ NOAA tide stations.
SLEEP. JULES KEEPS WATCH.
Drop the hook and Jules takes the deck. Predictive drift detection tells real drag from a normal swing, so the alarm fires for danger — not for a wind shift. An OS-level geofence keeps watching even if iOS closes the app: the alarm still fires. Monitor the boat remotely from ashore.
ASK ANYTHING, CAPTAIN.
Jules reads your live vessel state — position, wind, tide, depth — and calls 13 real data tools to answer: weather briefings, tide windows, anchorage scoring, route plans, nearby vessels and more. Ask in plain words or tap a suggestion. Jules replies in your language.
SPEAKS YOUR LANGUAGE.
Fully localized in 13 languages — charts, alarms and Jules.

I keep getting drag alerts when clearly the boat has not moved...
Don’t waste your money
Single-D
I was looking forward to using this app after reading the reviews but lets give an honest review under practical application. I sail/anchor in Mexico where there is little cellular coverage in remote places. The first night we used it the alarm went off at 2 a.m., after checking my other anchor drag apps we determined we had not moved at all. The next day went to check our position and the app had lost my position all together and I had to set to last position. I used the app for three weeks straight every day and it frequently just lost our position and had to be reset to last position, I had to set the position manually every time, and the use of the app is not intuitive as you would expect it to be. It would be nice to have the app always be on so you could quickly glance at your position and know everything is ok but it goes to sleep and most time just loses you position. This app is frighting enough I would even like my money back and I will not use this in the future.

What happened to the old app?
Slightly Irritated User
I’ve been using the app for years and loved it. Simple and straight forward and reliable. When I used the app at the end of last season it was great! Went to use it for the first time this year and what happened to it? It Is not even close to the same. In fact I closed it out and looked through my apps to see if had opened a different anchor app. It is now so complicated and does not show your track in your anchor circle so you know where you have been swinging. It no longer has augmented reality which is a feature I loved. It’s not easy to set your anchor radius distance. There is too much “stuff” on the screen and too many different screens now. I could go on and on. Needless to say I am now looking for a new anchor app. Too bad they had to go and ruin it. I hate it!
Not Reliable...but a well planned app
s.v providence
I downloaded this to monitor remotely, it’s one of the only anchor alarm apps that allows real-time tracking via another device. This is a fantastic feature. Unfortunately the app on my iPhone and two other iPhones will freeze. We live aboard our yacht and our anchor position is vital to our safety. This is a secondary anchor alarm to supplement our main chartplotters anchor alarm which is rock solid, however even as a backup, it has to work. Any freezing or crashing is simply unacceptable for something so important. If the developers can get that issue worked out, this will be the best alarm app on the store by miles.
Developer Response
Kindly upgrade the latest version in order to fix the issue. It is no more freeze or unexpected crash. It is reliable.
