About the developer:

Rain Viewer: Radar & Layers is built by an independent iOS developer based in Bavaria, Germany. I design, implement, test, and maintain the entire app myself. New features and improvements are driven by user feedback, and my own daily use of the app for weather planning.

Version History With this update, you can keep an even closer eye on rain and tropical cyclones—and read your weather maps more easily.
• Arrival arrow: See which direction precipitation is moving and when it is expected to reach your selected location. Available for Germany and parts of the surrounding areas.
• Clearer legends: A new vertical colour scale, with values displayed beside each colour, makes your weather maps easier to understand.
• More tropical cyclones: In addition to data from the National Hurricane Center, the app now displays storms tracked by the Joint Typhoon Warning Center—including systems in the northwestern Pacific, the northern Indian Ocean (the Bay of Bengal and Arabian Sea), the southern Indian Ocean, and the South Pacific. 2.22.0.7 17h ago - New temperature map for Europe:
View 2 m temperature data from DWD with a more colorful, higher-contrast design than the standard temperature map

- New temperature anomaly map for Germany (DWD):
See where monthly temperatures were warmer or colder than the 1991–2020 average, from -4 °C to +4 °C.
Use the slider to select the current month or any of the past 12 months

- New precipitation anomaly map for Germany (DWD):
See where monthly precipitation was above or below the 1991–2020 average, from -80% to +80%.
Use the slider to select the current month or any of the past 12 months

- New pollen forecast map (DWD):

Use the slider to select a day. 2.21.0.5 Oct 5 For an even clearer view of the weather:

A new European pressure map based on ICON-EU data from the German Weather Service (DWD). Colour-coded areas show mean sea-level pressure across Europe, while isobars and animated wind particles make weather patterns easy to understand—for example, whether warm air is flowing in from Spain or cold air is arriving from Scandinavia.

See European weather conditions at a glance with weather symbols for selected locations.

An improved hurricane map with forecast tracks, uncertainty cones, and forecast points showing the expected time, wind direction, and wind speed. 2.20.0.13 Sep 30 Rain Viewer just got even more powerful: You can now display near real-time satellite imagery directly in the app — powered by three major data sources for maximum coverage and detail:

• EUMETSAT for Europe and surrounding regions
• NOAA GOES for the USA, Atlantic, Pacific, and adjacent areas
• NASA GIBS for global satellite imagery worldwide

This gives you significantly improved, worldwide cloud coverage — perfect for tracking large-scale weather patterns. Follow hurricanes across the Atlantic and Pacific, or monitor developing low-pressure systems over the Mediterranean. Recent signs of a possible “Mediterranean hurricane” (medicane) in the Ionian Sea, for example, can now be tracked especially well with these new satellite images.

The satellite imagery complements your familiar rain radar data perfectly: while radar shows where it’s currently raining, satellite images reveal where clouds are forming, how they’re moving, and how major weather systems are developing — anywhere on Earth. 2.19.05 Sep 20 - Track tropical low pressure areas, storms and hurricanes monitored by the NOAA National Hurricane Center directly on the map
