Im Abo kann man dazu aus verschiedenen Modellen auswählen. Das System, mit dem Finger durch auf/ab oder links/rechts swipen langsam oder schnell durch die Zeit zu wandern, ist genial. So sieht man Wetterumschwünge schon in der Entwicklung und kann die grundlegende Wetterlage gut abschätzen. Durch Hereinzoomen sind diese Entwicklungen auch punktgenau untersuchbar. In der Basisversion kann man schon mit GFS, ECMWF oder dem kanadischen Modell ganz brauchbar arbeiten. Besser wirds im Abo u.a. mit Icon D2 oder Arome. Der Entwickler arbeitet ständig an Verbesserungen und er antwortet schnell und zuverlässig. Tolle Leistung! Update Mai 2026: Inzwischen nutze ich fast nur noch diese App. In Norddeutschland kann ich neben Icon auch Arome und inzwischen auch das 2km-Modell des niederländischen KNMI verwenden. Exzellent! Und bei Aufenthalten in Griechenland und auf Zypern war bislang auch das Icon EU-Modell meist sehr geeignet. Dieser grafische Ansatz in Verbindung mit vielen fantastischen Details (man kann z.B. die grafische Skalierung vieler Elemente feinsteuern, also z.B. Temperaturen nur in 5 Grad-Schritten statt stufenlos oder jede beliebige andere Kombination) ist nicht nur einzigartig, sondern auch in Verbindung mit Werbe- und Trackingfreiheit unfassbar nutzerfreundlich. Die anderen bunten grafischen Anbieter mit ihren regelrecht überladenen Anzeigen, die mehr verdecken als aufklären, lasse ich inzwischen links liegen. Danke, Duane! ### 5/5 — Graphics Ferrari *2026-05-29* This app makes the others seem like they're for children. Need an example? At the bottom right touch the circle cross, uncheck all data except Humidity, check Save, with two fingers pan to the Pacific ocean, widen fingers to zoom out, place your thumb lightly on the left side of the screen, slowly slide it to the right... THAT is what Humidity looks like when it's roiling around in the atmosphere!!! it's just amazing ### 5/5 — Best weather app *2026-03-07* Truly a great app - you can tell the developper is doing this not for $ but because they care before anything about functionnality. Great for people who want to know (and see) weather (and weather systems) and forecasts at a glance. ### 5/5 — Excellent WX app *2026-02-23* If you’re ready to take your WX observations and modeling to the next level, this is the app you’re looking for. Take the time to look it over and understand the features. It’s top tier for your collection of forecasting apps! ### 5/5 — Great app and very dependable *2025-09-27* I have had this app on several phones, android and iPhone. It is a must for me. I have had the bronze subscription and I really enjoy and having peace of mind especially during hurricane season. Thank you so much for a wonderful app and I will always have this app on my phone. It is a mainstay and necessity. I’ve never had problems or issues just a very dependable and unique app. Flowx is my first app of choice for hurricane season. Thank you again for a dependable and accurate app. Thank you for a continual wonderful and excellent app ### 5/5 — Perfect weather app *2025-04-20* This is a great app that provides all the data you need for predicting the weather. A widget would make this app 11/10! ### 5/5 — Great app! *2024-11-23* The design of this app is fantastic - intuitive, visual and interactive - nothing else like it on the App Store. Well done! ### 2/5 — No widgets *2024-10-07* No widgets available on iOS **Developer response:** Hi, it's on the to do list ### 5/5 — Accession to the rarefied atmosphere of astounding weather apps *2024-09-23* Finally, another discovery for me - one of those rare, highly capable weather-data processing and presenting apps. ‘Cause that’s exactly what they’re doing. Similar to (though not quite as amazing as) the data accumulation and presentation of Earth.Nullschool on the web, all of these applications use current and forecast-model data from around the world to put together a weather forecast for you, which is not the normal pre-digested junk available on every corner. Why would you need an app to pull in kindergarten stuff like that? Like Windy.app, this is what weather data nerds really want. But don’t be put off. You don’t have to be a mathematical wizard with atmospheric thermodynamics to use these apps. They elegantly bridge the gap between high-end weather + climatological data and the weather forecast needs of regular people like us. I’ve just started examining this one as it’s new for me, but it’s interactive functionality and presentation of model output from national systems puts it in the absolute elite of weather forecast applications. With the capability that this tiny group of applications offer, they are well worth paying for. This one in particular seems very low priced, especially given its truly inspired user interface. I have no personal or business association with the company or coders at all, they have never communicated with me, and I have just paid for the application at market price out of my own pocket by my own fascinated decision. But its functionality is quite extraordinary. I can only end with - Wow! **Developer response:** Thanks for the review! ### 5/5 — Great app and very dependable *2024-08-05* I have had this app on several phones, android and iPhone.
