What's New in VeriSky

1.5.2

August 20, 2026

- 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.

Wetter-App für Wetterbegeisterte

Eine wirklich gelungene Wetter-App mit einem interessanten Konzept. 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.

Beste Wetterapp

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!

Fantastic!

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.
