March 2026 — An indie developer and sailor has released WindRouter, an iOS app that brings together everything a sailor needs when dreaming about, researching, and preparing for an ocean crossing. It costs $3.99 with no subscription and no account required.

Planning a passage usually means bouncing between forums, PDFs, outdated websites, and half a dozen apps. Where do you clear in? What’s the best season? Which anchorages are worth stopping at? WindRouter puts all of that in one place, so you can read up, explore your options, and start your research from a solid foundation.

What’s inside

• 8 ocean passages with seasonal windows, prevailing conditions, currents, and hazard notes. Covers the ARC route, Coconut Milk Run, Bay of Biscay, Caribbean circuits, and more.
• 200+ curated anchorages across the Caribbean, Mediterranean, Pacific, and Atlantic, each with protection ratings, depths, holding info, and local tips from cruisers.
• 50+ country guides with ports of entry, clearance procedures, visa requirements, fees, VHF channels, and cruising seasons.
• Digital logbook with automatic GPS tracking, weather capture per entry, and GPX export.
• 15+ polar diagrams for popular cruising boats.
• Weather overlay with GRIB data from NOAA GFS and ECMWF models, helpful for getting a feel for conditions along your planned route.

Built for the planning phase

WindRouter isn’t trying to replace dedicated routing software. It’s the app you open months before departure, when you’re still figuring out which passage to take, what to expect along the way, and what you’ll need when you arrive. Think of it as the guidebook you wish existed when you first started looking into offshore sailing.

Privacy-first, offline-first

No account, no tracking, no cloud. All content is stored on the device and works fully offline, which is useful both at sea and in remote anchorages with no signal.

Who it’s for

Sailors researching their first offshore passage, cruisers planning a Pacific crossing or heading south to the Caribbean, and anyone who wants passage info, anchorage guides, and country clearance details in one place. Sailors planning an Atlantic crossing or the Coconut Milk Run will find the Pacific and Caribbean data especially relevant.

Availability

WindRouter is available now on the App Store for $3.99 (one-time purchase).
