Why we think so

warnwetterapp.de hosts the official WarnWetter app by Deutscher Wetterdienst (DWD), Germany’s national meteorological service. The website ranks around #2.87 million globally with about 7,365 monthly visits mainly from Germany. It uses standard, secure web technologies and does not appear on any scam or phishing blacklists. Reviews highlight the app's reliability for severe weather alerts and its ad-free model, but some users report radar inaccuracies and usability issues. Legally, the app faced disputes because DWD must restrict free content to official warnings only, with other weather info requiring fees after a 2020 Federal Court ruling. Overall, it is a legitimate government service with some user experience limitations.
