One clean, animated map of wind, waves and weather from the world's best models, with official warnings and live hurricane tracks drawn on it. Download a region and it works with no signal. No ads, no account.
Seven layers as flowing streamlines and smooth colour heatmaps. Switch instantly, read the conditions anywhere.
Tens of thousands of particles flow with the wind, speed in colour. Read it at the surface or up through seven pressure levels to 250 hPa.
Peak gust, not sustained wind — the number that decides whether a sail, wing or small boat is manageable.
Wave height and direction as a smooth heatmap. Switch to peak period to tell clean groundswell from short, steep windchop.
Rain and snow intensity, frame by frame, so you can watch systems track in and clear out.
Low cloud — whether you get sun, grey, or a usable window to fly or shoot.
Air temperature at 2 m, in °C or °F.
Raw forecast grids turned into something you can see — animated, interactive, and precise to the point you tap.
With WindTrac Pro, download a region and its full forecast — wind, waves and the basemap — and the map keeps working with no connection at all: offshore, in the backcountry, wherever coverage drops. Pro also extends forecasts beyond 24 hours.
Run NOAA GFS worldwide, DWD ICON-EU for high-resolution Europe, or ECMWF's AIFS and IFS HRES, plus GFS-Wave and ECMWF wave models. Pick the model per layer, so wind and waves can come from different sources.
Forecasts show what the atmosphere is doing. Storm Watch shows what your weather service has decided to warn about — on the same map, free.
Live alerts from the US National Weather Service and Environment Canada, drawn as the real warning polygon or zone. Tap one for the full official text, and choose which categories you see.
Active cyclones from the NOAA National Hurricane Center: forecast cone, track and 34-knot wind field. Scrub the timeline and the wind field moves along the track, showing when tropical-storm-force wind reaches you. Areas under watch appear before a storm is named.
Observed tornado, wind and hail reports from the NOAA Storm Prediction Center, plotted with the measured gust or hail size.
The same map, layers and models on every screen. One App Store subscription covers iPhone, iPad and Mac.
A sidebar for layers and places, the map in the middle, and an inspector for the layer's model, altitude, units and storm overlays. Right-click to save a spot, pinch to zoom, and switch layers with ⌘1–⌘7. Offline maps included. Requires macOS 26 or later.
Open iPhone Duo and the map spreads across the whole inner display. Closed, or open in landscape, the controls move into the side bar, off the forecast. Fold mid-session and the layout follows.
Every layer comes from public data published by national and international weather agencies. Choose the model that fits your region.

Yes, and they are free. WindTrac draws live watches, warnings and advisories from the US National Weather Service and Environment Canada directly on the map — the true warning polygon for storm-based products like tornado and severe thunderstorm warnings, and the county or marine zone for the rest. Tap an alert to read the full official text and instructions. You can switch individual categories on or off under Storm Watch in Settings.
Yes. WindTrac shows active tropical cyclones from the NOAA National Hurricane Center, including the forecast cone, the forecast track, and the 34-knot (tropical-storm-force) wind field. The wind field is tied to the timeline, so scrubbing forward moves it along the track and shows when damaging wind is forecast to arrive. Areas being watched for development are shown before a storm is named. Coverage is the Atlantic, eastern Pacific and central Pacific basins, which is what the National Hurricane Center issues.
No. WindTrac is an independent app built by Rivolu LLC. It displays public data published by NOAA, the US National Weather Service, the National Hurricane Center, Environment Canada, ECMWF and DWD, but it is not affiliated with, endorsed by, or approved by any of them. Always follow official warning sources; WindTrac is not a substitute for them.
Yes. WindTrac is a native Mac app on the Mac App Store, for macOS 26 or later. It has a sidebar for layers and saved places, an inspector for the layer's forecast model, labels and storm overlays, right-click to save a spot or copy its coordinates, menu-bar commands with keyboard shortcuts, and scroll-wheel and pinch zoom. It is the same App Store app as on iPhone and iPad, so a WindTrac Pro subscription covers all three.
Yes. WindTrac is made for iPhone Duo. Unfolded, the map, timeline and altitude slider spread across the whole inner display. On the outer display, and on the inner display in landscape, Layers, Location, Offline Maps and Settings move into iPhone Duo's side bar so they stay off the map. The layout follows the device as you fold and unfold it.
WindTrac is an animated, interactive forecast map for wind, waves, and weather. It shows flowing wind particle streamlines across the globe, plus wave and precipitation layers as smooth color heatmaps. You can scrub a timeline through the forecast, tap anywhere to read exact values, and switch between several forecast models. It is a native app for iPhone, iPad, Mac and Android, and works fully offline once you download a region (Pro).
Yes. The full interactive map, every layer, every forecast model, timeline playback, tap-to-read values, and Storm Watch are free — with no account. Free forecasts cover the next 24 hours, and you can save five locations. WindTrac Pro unlocks offline maps, forecasts beyond 24 hours, and unlimited saved locations.
WindTrac is built on public forecast data: NOAA GFS (global), DWD ICON-EU (high-resolution Europe), ECMWF AIFS (an AI model) and ECMWF IFS HRES, plus GFS-Wave and ECMWF wave models. You can switch the model independently for each layer, so wind and waves can come from different sources at once.
WindTrac Pro unlocks offline maps — download a region and its forecast for use with no connection — and extended forecasts beyond 24 hours, plus unlimited saved locations. Pro is $29.99 USD a year, or available monthly, each with a 7-day free trial. On Apple devices one subscription covers iPhone, iPad and Mac.
Subscriptions are auto-renewing and sold through the Apple App Store on iPhone, iPad and Mac, and Google Play on Android. On iPhone or iPad, manage or cancel in your Apple ID settings (Settings → your name → Subscriptions); on a Mac, in the App Store app (your name → Account Settings → Subscriptions); on Android, in Google Play → Payments & subscriptions → Subscriptions. The 7-day free trial converts to a paid subscription unless you cancel at least 24 hours before it ends.
With WindTrac Pro you can download a region and forecast for offline use — handy offshore or anywhere coverage is unreliable. The free tier needs a connection to fetch forecast and basemap data.
No. WindTrac uses your device location only to center the map on your current location and to determine the viewed location's time zone, which is reverse-geocoded on your device. Your location is not sent to or stored on WindTrac servers. See our Privacy Policy for details.
WindTrac is the best simple, ad-free alternative to Windy: the essentials you can read at a glance — wind, gusts, waves, wave period, rain, cloud and temperature, the same class of forecast models (GFS, ICON-EU, ECMWF AIFS), and full offline downloads — free on iPhone, iPad, Mac and Android, with no account. Windy offers far more layers and parameters; WindTrac trades that breadth for simplicity, no ads, and offline use. See the full WindTrac vs Windy comparison.
