About this app
Ever wondered how accurate your weather forecast actually is? VeriSky lets you find out, and pick the model that works best for you.
Most weather apps choose a model for you, or quietly blend a few. But no single model wins everywhere. The one that nails temperature in your city might be hopeless at wind, or great for tomorrow yet useless a week out, and the best model can differ between towns just miles apart.
VeriSky scores how each model has actually performed at your exact location over the past days, weeks, and months, separately for temperature, rain, wind, and sun. It also shows how far ahead each stays reliable, so you know which to trust short-term and which for the long haul.
Switch between the top global models, all free:
- ECMWF IFS: the gold standard in global forecasting
- ECMWF AIFS: ECMWF's new AI-powered model
- GFS: NOAA's widely-used American model
- AIGFS: NOAA's new AI-powered model
- ICON: Germany's DWD high-resolution model
Show several at once to see where they agree, or blend them into one confidence score for every hour and day.
Time Travel: drag back up to 7 days to see what a model predicted on earlier days, laid over what actually happened. One glance tells you how much to trust tomorrow's forecast.
Plus charts for temperature, sunshine, UV, precipitation (rain vs. snow), wind, cloud, humidity, pressure, and marine (waves, currents), a wind map, Feels Like temperature by default, and home-screen widgets, all in one app.
Free. No subscription. No login. No ads. No data collection. Just weather, verified.
