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 and lock screen widgets, all in one app. Past hours are measured, not modelled. Where radar reaches (Europe, the United States and southern Canada), the rain behind you comes from observed radar, so a shower that fell at 14:00 sits at 14:00. Pair your own Ecowitt personal weather station and its readings become the past hours at that place, and the truth that grades every model there. Lock screen widgets keep the next hours in view without unlocking your phone. No login. No ads. No data collection. Just weather, verified. VeriSky Pro, optional: - Commercial forecasts: add Apple Weather, OpenWeatherMap and Visual Crossing to the comparison, scored at your location against what actually happened - Your locations, scored: pick up to 10 saved places and have every model collected and verified there, like at the airports - Rain nowcast: minute-scale radar outlook for Europe, the United States, Canada and Hong Kong, plus a satellite rain nowcast for Thailand - Sports: best-window finder for running, hiking, cycling, sailing, kitesurfing and gliding, with advanced charts, spot settings and personal limits Commercial model standings on the Score tab stay free for everyone, and the nowcast in the Netherlands stays free too.

Besonders gefällt mir, dass man verschiedene Wettermodelle vergleichen und deren tatsächliche Trefferquote nachvollziehen kann. Die vielen Diagramme, Statistiken und Verifizierungsfunktionen bieten deutlich mehr Informationen als die meisten anderen Wetter-Apps. An einigen Stellen könnte die deutsche Übersetzung noch etwas überarbeitet werden, da einzelne Formulierungen etwas holprig wirken. Das ist aber nur ein kleiner Kritikpunkt. Insgesamt ist VeriSky übersichtlich, informativ und macht genau das, was sie verspricht. Klare Empfehlung für alle, die sich intensiver mit Wettervorhersagen beschäftigen möchten. ### 3/5 — Avis *2026-07-16* Dans l’onglet comparer il y a une rubrique «  comment ça sent ? «  De quoi s’agit-il ? **Developer response:** Merci de l'avoir signalé, cela a été traduit par « Quel est votre ressenti ? » ### 5/5 — Beste Wetterapp *2026-07-15* Ich habe schon sehr viele Wetter Apps in all den Jahren probiert. Diese ist mit Abstand die beste von allen! Sie ist übersichtlich, man kann sehr viel individualisieren und das schönste ist, dass man sich die Wetter Modelle für die Vorhersage auswählen kann, die man am zuverlässigsten erachtet. Man sieht auch rückwirkend, welches Wettermodell in den letzten Wochen und Monaten am zuverlässigsten bestimmte Prognosen wie Temperaturen vorhersagen konnte. So hat man die Möglichkeit, sich das Wettermodell für die Vorhersage auszuwählen, welches man möchte. Man kann auch mehrere Wettermodelle auswählen und es werden Durchschnittswerte für die Vorhersagen gebildet. Das bietet sonst keine andere App! Ich bin restlos begeistert! ### 5/5 — Fantastic! *2026-07-11* One of the most innovative weather apps I’ve seen. Really fantastic to be able to see score cards for how well the various models have been working. It helps you answer “which model has been tracking the best against the actually weather in my area”. Being able to see historical weather forecasts is also a real bonus. Perfect tool for someone that really wants insight into how weather modeling and forecasts work. ### 5/5 — Fantastic App *2026-07-03* Amazing idea and it keeps getting better. Awesome! ### 5/5 — The best weather app *2026-07-03* This deserves to be a promoted app by Apple. With a list of weather prediction services it allows you to see which one consistently provides the best weather predictions for your locale. Such a smart take on a weather app, it is now my go to. The UI is also well laid out. And it’s free! ### 5/5 — Great to have a spectrum *2026-07-01* Enjoy being able to review weather data for more precise information regarding tornado alley in the US ## Frequently asked questions about VeriSky ### How accurate is VeriSky?

Where radar reaches (Europe, the United States and southern Canada), the rain hours behind you come from observed radar, so a shower that fell at 14:00 sits at 14:00. - Pair your own Ecowitt station. Past hours at that place show what your station measured, and your station grades the models on the Score tab. - Chart lanes can now name where their past hours came from. Tap a marker to pick the source that lane trusts. - A new Continuous graph reads the whole week as one chart instead of rows. - Sports now live in one place (PRO): one Sports button, and a week grid of every sport and every spot. - Widgets on your device location follow the phone, and errors now say what actually broke. ### 1.5.4 — 2026-09-01 - Two new sports: Hiking and Running (PRO). VeriSky grades every hour of the week and picks the best windows to go. Hiking counts muddy trails from the rain in the last 24 hours, plus visibility, UV, lying snow and the height you climb. Running weighs how heavy the air feels through the dew point, because 24 °C at 90% humidity is not the same run as 24 °C at 40%. Open a day to see exactly what its verdict was graded on. - Rain nowcast for Thailand (PRO). The rain map now runs on a live satellite nowcast: a fresh rain field from Himawari-9 every 10 minutes, carried up to two hours ahead. - New profile picker. Pick how you use VeriSky, from The essentials to Model watcher, Wind & water or In the air, and see exactly which settings a profile changes before it changes them. New users get it while setting up, everyone else finds it in Settings under Profile. - The hour axis now freezes to the bottom of the screen while you scroll a day chart, so the wind, humidity and cloud lanes always have their times underneath. - Lock screen widgets: a model card, temperature, wind and UV, plus a "Next Rain" line above the clock that counts down to the next shower from the nowcast (PRO). - The current conditions on Today read a real observation again, whatever model you have selected. - Roads, railways, rivers and borders are now drawn over the wind, rain and gliding maps, for everyone. ### 1.5.3 — 2026-08-26 - Much faster wind, rain and gliding maps. The maps now paint pre-rendered fields from the VeriSky server instead of building them on your phone, so they load and scrub without the wait. - The VeriSky Blend on the Today tab now comes from the server, whichever model you have selected, so it loads much faster. It mixes the models with the best recent scores for your location. - New Custom blend setting if you would rather keep blending the models you enabled yourself on this device. - Time travel now works on the blend in the Verify tab, so you can see what the blend said in an earlier run. - New current map and wave map for Marine (PRO). - Small fixes to the widgets. - Interface fixes throughout. ### 1.5.2 — 2026-08-20 - New scoring method that rewards accurate, decisive forecasts without favoring models that simply smooth out changing weather. Expanded results explain accuracy, performance during extremes, typical error and forecast sharpness. - Added interactive regional map showing which weather models perform best at different locations. - Added five iOS Lock Screen widgets for conditions, temperature, wind, UV and next rain. - Added model variants for power users, exposing regional and global members inside seamless models, with their resolution, coverage and forecast range. - Redesigned “How does it feel?” into structured, anonymous weather feedback. Legacy on-device bias correction remains available separately. - Widgets can now show dew point instead of relative humidity, and chart widgets show today's high and low. - Embedded wind, marine and gliding maps can now open full-screen. - Improved forecast summaries, chart readability, time-travel controls and handling of incomplete model data. ### 1.5.1 — 2026-08-01 - Added TMD (Thailand) weather forecast model - Added Foreca forecast model (PRO) - Showing Blend (Today tab) in score tab now - Items are movable in day-detail sheet - Accordion view fully functional now - Fixes for maps, nowcast, and rain score ## Apps similar to VeriSky | App | Rating | Price | Category | | --- | --- | --- | --- | | [Dusty - Air Quality Visuals](https://appshunter.io/ios/app/dusty-air-quality-visuals/id1495009199) | 4.5 (57) | Free | Weather | | [Comparecast: Weather Models](https://appshunter.io/ios/app/comparecast-weather-models/id6771171777) | 5.0 (4) | Free | Weather | | [Only Radar: Weather Radar](https://appshunter.io/ios/app/only-radar-weather-radar/id6780737563) | 5.0 (1) | Free | Weather | | [WeatherGlow - Local Forecast](https://appshunter.io/ios/app/weatherglow-local-forecast/id6451098166) | 4.9 (31) | Free | Weather | | [Solar Weather](https://appshunter.io/ios/app/solar-weather/id584490475) | 3.4 (5) | Free | Weather | | [Burnie: UV Index & SPF Timer](https://appshunter.io/ios/app/burnie-uv-index-and-spf-timer/id6770673915) | 4.9 (11) | Free | Weather | ## More apps by Nick Leenders - [Boat Maps: Amsterdam Canals](https://appshunter.io/ios/app/boat-maps-amsterdam-canals/id6763041387) All apps by Nick Leenders: https://appshunter.io/developer/1877658009 ## Related topics [ecmwf](https://appshunter.io/ios/topics/ecmwf) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
