SturmVorwarnung
A hyperlocal German storm and heat-warning assistant that tells your household exactly what to do, and where, before the weather hits.
Bavarian and North Rhine-Westphalian households planning gardens, school events, or weekend outings
- 30-minute-ahead DWD warning for your exact address, not just your Landkreis
- Per-warning action checklist in German: close Dachfenster, move car under cover, secure Trampolin
- Combined Pollen + Hitzewarnung view for school kids and elderly relatives
- Multi-location mode so Oma, the Schrebergarten, and the school each get their own alert
DWD already publishes rich regional data but consumer weather apps do not translate warnings into household-level actions.
Strong baseline demand confirmed: official DWD WarnWetter app plus NINA/KATWARN/WetterOnline dominate a $52.6M (2022) German weather app market growing ~6% CAGR, and the source 'blitz' trend shows 1000+ searches, but the household-action translation angle is unvalidated beyond general severe-weather interest.The Best Weather Apps for Germany: Always on the Safe Side ↗Germany Weather App Market Report With Global Overview ↗
No competitor found that specifically translates DWD municipal-level warnings into household-level action checklists (gardens, school events, outings); BBK publishes generic 'what to do' text only, and government apps focus on warnings not behavior — but WarnWetter's premium tier and WetterOnline's depth crowd the adjacent space.Our services - WarnWetter App - Deutscher Wetterdienst ↗Wetter-Apps im Check: Welche am zuverlässigsten warnt ↗
Monetization is constrained: WarnWetter's full version is a one-time InApp-Kauf (per BGH ruling) and BBK behavior guidance is free; the German weather app market totals only ~$52M and household-action translation is an undifferentiated LLM wrapper layer that households can get from free generic sources.WarnWetter-App ↗Germany Weather App Market Report With Global Overview ↗
Exceptional longevity: rising extreme weather and heat events in Germany, expanding DWD data products, and climate-driven baseline demand make this category durable for 10+ years regardless of specific product.Deutscher Wetterdienst - Amtliche Unwetterwarnungen und Wetterwarnungen ↗
Very feasible: DWD data is public and already consumed by NINA/KATWARN; an action-translation LLM layer over municipal warnings plus push notifications and Bavaria/NRW localization is a standard mobile app build with no regulatory or data-acquisition blockers.Our services - WarnWetter App - Deutscher Wetterdienst ↗
