How accurate a weather app is depends heavily on location. Windy and Mercury Weather combine several models and are often more precise than any single source; global providers show impressive radar maps, but their local accuracy for Germany varies. Apps with DWD (Deutscher Wetterdienst) data or a MeteoGroup connection often do better on precipitation. The September 2026 update adds Anemogram, the publisher's own development, placed at the top of the list, with prices checked across the field. The comparison weighs which data sources an app uses — DWD, ECMWF or Open-Meteo — hourly and daily forecasts with rain probability, a radar view for current precipitation, integrated local severe-weather warnings, outdoor data such as wind, waves, UV index and visibility, and whether the interface makes sense without a meteorology degree. Widget quality matters too, since many people check the weather dozens of times a day.
Our verdict
Anemogram is the publisher's own development and therefore not a neutral recommendation: anyone planning something outdoors gets wind, gusts, tides and the night sky as a continuous timeline, free and ad-free. Anyone who only wants tomorrow's temperature is best served by Yr — free, ad-free, accurate and with one of the nicest designs in the App Store. Those wanting more control — their own data sources, dark humor and the best widgets — choose CARROT Weather, which needs a subscription.
Weather on the Way is an insider tip for frequent drivers, with forecasts along the route that suit road trips. DWD WarnWetter belongs on every German iPhone as a backup, since nobody delivers official severe warnings faster. Ventusky is ideal for weather nerds who love global maps, WeatherPro has a solid MeteoGroup base but feels dated, and Dumb Weather shows only the temperature — sometimes that is exactly enough.
Windy.com draws wind, rain, temperature and clouds on a real-time map of the world, using models including ECMWF, GFS and NOAA, with several models switchable and comparable in one view. Pilots, sailors and outdoor athletes are its named audience.
The core app is free; Premium at around €20 per year unlocks higher model resolution, more weather layers and extended sounding data, which casual users rarely need. The source calls it essential for wind-dependent sports.
CARROT Weather wraps professional, selectable data sources and a full set of widgets and Apple Watch complications in sarcastic humor; users can compare several sources instead of being tied to one, and the source calls its widget selection the best in the field.
The base is free; the Ultra subscription at around €5 per month adds rain radar, a time-machine feature and AR weather. Full access costs more than plain weather apps, and anyone who does not share its English humor loses much of the appeal.
Aviation Weather serves pilots with METAR and TAF data and, through the paid upgrade, detailed NOTAM views, extended radar imagery and winds-aloft information. It is designed for quick access to flight weather on the ground and in the cockpit in a compact, ad-free layout.
The core data is free and the app is freemium; the source is clear that it makes sense only for aviation users and is not a general consumer weather tool.
Windfinder specializes in wind and waves for sailors, surfers and kitesurfers: forecasts for around 160,000 spots, tides for about 20,000 places and live readings from weather stations, with wind alarms when conditions hit a chosen threshold.
The core app is free; Plus, monthly or yearly, unlocks the hourly Superforecast, wind alerts and ad-free use. The source considers it better in this niche than any general-purpose app.
Mercury Weather combines several weather models and displays the uncertainty between them, which the source calls the most scientific approach in the consumer field; hourly rain forecasts and detailed diagrams come in a polished app with an Apple Watch companion.
Core functions are free; Mercury Pro, a subscription, adds extra radar options, notifications and more locations. It suits planners who want precise hour-by-hour forecasts rather than a single daily number.
Weather on the Way forecasts weather along a driving route rather than only at the destination, showing what to expect hour by hour on longer trips, road journeys, bike tours and hikes — a clear niche the source calls genuinely useful for frequent drivers.
The base is free; Pro at around €2 per month adds hourly updates and weather animations along the route. Anyone wanting only current conditions in one place, or unwilling to subscribe for occasional use, should skip it.
DWD WarnWetter is the official app of the Deutscher Wetterdienst, delivering severe-weather warnings down to individual German municipalities with precise warning levels, and the source treats it as the most reliable warning channel in the country.
It is free and tax-funded with no premium tier. The interface is not attractive, but data comes straight from the source; the source calls it a mandatory second app on German iPhones, with Apple Watch warnings included.
Yr comes from the Norwegian meteorological institute and broadcaster and is free, ad-free and tax-funded, with a minimalist design and accuracy the source calls above average for Northern Europe and high mountains, which makes it a favorite for hikers.
It offers no warnings specific to Germany and no German features such as pollen counts; its strength is clean, precise general forecasting in one of the App Store's most attractive packages, and the source names it the best pick when you only want tomorrow's weather.
Ventusky animates wind, rain and other weather patterns on an interactive global map, with several models comparable for a more informed forecast and the hour-by-hour development of systems; the source calls it excellent for visual weather analysis.
The base is free; Plus at around €3 per month adds extra weather models and removes ads. It is too complex for everyday quick checks and too data-heavy for users who want a plain forecast.
Dumb Weather is the deliberately minimal option: one number and one sentence, with no menus, maps or extra information, free, ad-free and supported by its developer. It answers the morning umbrella question and nothing more.
Anyone wanting rain radar, severe-weather warnings or hourly forecasts for outdoor activities loses out; the app exists for users who want every bit of interface overhead removed.
WeatherPro supplies detailed professional meteorological data from MeteoGroup, now DTN, with many parameters, bio-weather and pollen information and hour-by-hour forecasts for enthusiasts and users who care about local detail.
The source describes the experience as dated and unsuitable for casual users. Pricing is inconsistent across the source itself — a €0.99 card label, a subscription text and a one-time-purchase text — so no single price is stated here and the conflict is flagged for review.
WetterOnline is the app of a long-established German weather provider, with detailed forecasts, rain radar and severe-weather warnings for Germany plus pollen and UV information in a plain, reliable interface for everyday use.
The free version is ad-funded; a separate WetterOnline Pro app with identical features removes ads for a one-time €29.99 purchase. The source sees no standout feature beyond solid local reliability.
Apple Weather is built into iOS 16 and later, free with no subscription or in-app purchases, and uses Dark Sky-derived data with minute-by-minute precipitation nowcasting and animated backgrounds.
The source considers it enough for most users day to day, with solid standard widgets, but offers little customization and no deep analysis; very precise local data in rural areas and advanced features are not its strength.

Questions & answers
Which weather app is the most accurate for Germany?
That depends on the weather service behind it, not the app itself. Apps with access to DWD data, such as WarnWetter, deliver the most reliable forecasts for Germany. CARROT Weather lets you choose the source yourself, so you can switch between MeteoGroup, AccuWeather and others and compare.
Do I need a weather app or is Apple Weather enough?
Apple Weather has improved considerably since Dark Sky was integrated, especially for next-hour precipitation, and it is enough for most people. If you want a better widget, rain radar or more detailed hourly values, an alternative such as Yr or CARROT Weather is worthwhile.
Which iPhone weather app is completely free?
Yr from the Norwegian weather service and DWD WarnWetter are fully free and ad-free. The basic version of Wetter.com is also free but shows ads. Dumb Weather costs a few euros once and has no running costs after that.
Which weather app has the best rain radar?
Ventusky offers the most detailed radar map, with global coverage and various overlay options. For Germany, DWD WarnWetter supplies the most accurate precipitation radar because it comes directly from the Deutscher Wetterdienst. CARROT Weather also integrates a good radar.
Which weather app has the best widgets?
CARROT Weather offers by far the most widget options, with various sizes, styles and data. Yr has an elegant, simple widget with the key information. Apple Weather supplies solid standard widgets, though they offer little customization.
