Most weather maps bury what matters under menus and ads. WindTrac is one clean, animated map you can read at a glance — wind, waves, and rain from the world's best models, no setup, no account. And it's the only one that downloads a full region for use with no signal. Powerful forecasts, refreshingly simple.
Wind, waves, and precipitation — rendered as flowing streamlines and smooth color heatmaps. Switch layers instantly and read the conditions anywhere.
Tens of thousands of particles flow along the wind field, with speed shown in color — a living picture of where the air is moving.
Significant wave height as a smooth heatmap, plus wave direction — so you can see swell building and where it's headed.
Rain and snow intensity painted across the map, frame by frame, so you can watch systems track in and clear out.
WindTrac turns raw forecast grids into something you can actually see — animated, interactive, and precise down to the point you tap.
WindTrac's standout feature: with WindTrac Pro, download a region and its full forecast — wind, waves, and the basemap — for use with no connection at all. The animation, layers, and timeline keep working offshore, in the backcountry, or anywhere coverage drops. Pro also extends forecasts beyond 72 hours; the free tier always covers the next three days.
Compare global and regional models without leaving the map. Run NOAA GFS worldwide, switch to DWD ICON-EU for high-resolution Europe, try ECMWF's AIFS AI model or IFS HRES, and overlay GFS-Wave or ECMWF wave models. The model is selectable per layer, so wind and waves can come from different sources at the same time.
Tap anywhere to read the exact wind speed or wave height at that point, with labels at notable extrema. Save the spots you watch and jump straight back to them, snap to your current location, and show times in your device's zone, the viewed location's zone, or UTC.
WindTrac doesn't guess. Every layer is rendered from public forecast data published by national and international weather agencies — choose the model that fits your region and your question.

From public forecast grids to a live map, in three steps.
Launch the app — no account, no setup. The wind comes to life immediately, anywhere on the globe.
Switch between wind, waves, and precipitation, and choose the model per layer — NOAA GFS, DWD ICON-EU, or ECMWF.
Scrub or auto-play the timeline, tap to read exact values, and save the spots you care about. Go Pro for offline and longer range.
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 iOS app, 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 saved locations are free — with no account. Free forecasts cover the next 72 hours. WindTrac Pro unlocks offline maps and forecasts beyond 72 hours.
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 72 hours. Pro is available as a monthly or yearly subscription, each with a 7-day free trial.
Subscriptions are sold through the Apple App Store as auto-renewing subscriptions, and you manage or cancel them in your Apple ID settings (Settings → your name → Subscriptions on iOS). 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 wind, wave, and precipitation essentials you can read at a glance, the same class of forecast models (GFS, ICON-EU, ECMWF AIFS), and full offline downloads — free on iOS, 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.
