The routing app trusted by Vendée Globe skippers. Advanced weather, multi-model GRIBs, smart routing — with ultra-low data use, even offshore.
The weather routing app trusted by the world's top offshore sailors.
Squid is the mobile version of SquidX — the routing solution used by elite teams in the Vendée Globe, Route du Rhum, Transat Jacques Vabre, The Ocean Race, and more.
Now that same professional-grade power is in your pocket. From solo ocean racers to weekend cruisers, Squid gives every sailor access to accurate multi-model weather data and smart routing tools — rebuilt for speed, simplicity, and offshore use.
A brand-new version has just launched: completely redesigned interface, major performance upgrades, and new features continuously in development.

Weather Coverage
Wind, gusts, MSLP, rainfall, cloud cover, CAPE, humidity, temperature, surface currents, swell & wind waves.
Great, user-friendly routing app also good for viewing high resolution GRIB files

I like Squid a lot because it’s easy to use and to demo to students (I’m a volunteer sailing instructor in the Caribbean, Mediterranean, and Lake Michigan).Squid is a simple, user-friendly routing app with sufficiently sophisticated functionality. For those wanting something even simpler, it can be used as a GRIB viewer with access to many high resolution models. It allows you to choose the boat’s polar and restrict the route with waypoints. For cruisers it’s useful to have parameters that allow the user to change the standard polars, scale them down to a certain percentage, and include running the engine if the boat speed drops below a certain amount.Each time I demo it, my students comment how great it is. I like very much myself so I highly recommend it.
Buggy, math errors

I would like the app, except it is very buggy. For example, it will route me on tight angles like TWA 40 degrees when my polars are super slow at that angle and I’ve entered in the advanced options to not go tighter than TWA 60. Or when it has me going 1.2 knots in 12 knots true wind speed and 11 knots apparent, which doesn’t match my polar at all. Or the confusion between boat speed and SOG: if I set it to motor a given speed in a strong current it doesn’t correctly add in how the current impacts my SOG. Often squid does give me reasonable routes for simple cases in open water and minimal current… but in complicated cases with stronger currents and complicated routes it’s useless.
A complete rebuild — faster, smarter, and more powerful than ever.
We rewrote the app from the ground up to hit new performance and reliability standards. Here's what's new:
• New visual engine — Géomonarque brings a redesigned cartography standard across all D-ICE software. Faster rendering, enhanced dark mode, map colors adapt to your theme.
• Multiple weather displays — View and compare several weather models simultaneously, with no performance hit.
• Dynamic tooltips & meteograms — Long-press anywhere on the map for live model values. The meteogram updates as you move.
• Multi-route comparison — Visualize and compare multiple routing results side by side to make better decisions.
• Integrated navigation — Launch turn-by-turn navigation directly from your chosen route. Customizable display, widget & lock screen support.
• New tides module — Manage and display tide charts directly on the map.
• Geo Garage partnership — Seabed data, online and offline.
• 11 languages — Squid is now fully internationalized.
The new era of navigation starts here.
