Regen? beantwortet die wichtigste Frage des Tages: Muss ich gleich einen Schirm mitnehmen? Die App zeigt dir ein animiertes Regenradar für ganz Deutschland und eine Vorhersage für deinen Standort – übersichtlich, schnell und ohne Schnickschnack. REGENRADAR Verfolge auf der Karte, wo es gerade regnet und wie sich die Regengebiete bewegen. Eine Zugbahn zeigt dir an, woher der Regen kommt und wann er deinen Standort erreicht. VORHERSAGE FÜR DEINEN ORT Sieh für die nächsten zwei Stunden, wie wahrscheinlich Regen ist und wie kräftig er ausfallen könnte – genau dort, wo du bist. EINFACH UND KLAR Zwei Ansichten, ein Fingertipp: Radarkarte und Standortvorhersage. Keine Anmeldung, kein Konto, keine Ablenkung. DATENGRUNDLAGE Die Niederschlagsdaten basieren auf den frei verfügbaren Radardaten des Deutschen Wetterdienstes. Die angezeigte Regenwahrscheinlichkeit wird aus der Radar-Intensität abgeleitet und ist als anschauliche Orientierung gedacht, nicht als amtliche Wettervorhersage. Regen? deckt Deutschland und angrenzende Gebiete ab.
