Helm WX gives you the marine weather data that actually matters — wind, waves, sea state, and tides together in one clean view. Built for boaters, sailors, and anyone who needs to know what the water is doing before they go out.
**Live data from real sources**
Helm WX pulls directly from NOAA weather stations, offshore buoys, and tide gauges — not a statistical model. You get actual observed conditions from the nearest station to wherever you're headed.
**Wind, waves, and tides — together**
Most weather apps show you one or the other. Helm WX shows wind speed and direction, wave height and period, sea state, and a full tide chart all on the same screen. Everything you need to make a go/no-go call in one place.
**Works anywhere in the world**
Enter coordinates, drop a pin on the map, search by city or port name, or tap Use My Location. Helm WX works offshore too — not just coastal areas.
**Save your spots**
Save up to 10 favorite locations and load them with one tap. Set a default home port and the app knows where to look first.
**Daily report notifications**
Schedule a morning push notification for your saved location. Know the conditions before you leave the dock.
**No subscription. No ads.**
Pay once, own it forever. $4.99 gets you the full app with no recurring charges, no data paywalls, and no ads cluttering up your screen while you're trying to read a wind barb.
