Servus Chiemgau, mobil am Chiemsee zu sein hat einen neuen Namen: Rosi! Das preisgünstige ÖPNV-Angebot ermöglicht bedarfsgerechte Busfahrten auf Abruf. Deine individuelle Fahrt ist auf unserer On-Demand-Plattform bequem und flexibel buchbar – von Montag bis Sonntag, ab 2,50 Euro pro Fahrt, ganz ohne Fahrplan. In einem Netz aus 619 Haltestellen in 11 verschiedenen Gemeinden im Chiemgau holt dich Rosi zur Wunschzeit am ausgewählten Startpunkt ab und bringt dich zuverlässig zu deinem vorher festgelegten Zielpunkt. Die Höhe des Fahrpreises ist dabei zonenbezogen. Er startet mit Zone 1 (bis 4 km) für 2,50 € und geht bis Zone 5 (ab 15 km) für 6,00 € (zzgl. 1,10 € pro weiterem km). Die App ermöglicht eine bargeldlose Zahlung mit Kreditkarte. Der Fahrpreis kann aber auch bar bei Fahrtantritt im Bus entrichtet werden. Deinen Zahlungsweg legst du bei Buchung fest. Der tatsächliche Fahrpreis wird dir vorab angezeigt. Mit Rosi kommst du dank einer Flotte aus Elektrofahrzeugen von Montag bis Donnerstag (7 bis 22 Uhr), aber auch Freitag (7 bis 3 Uhr), Samstag (9 bis 5 Uhr) und Sonntag (9 bis 20 Uhr) in folgenden Gemeinden schnell und zuverlässig ans Ziel: Aschau im Chiemgau, Bad Endorf, Bernau, Breitbrunn, Eggstätt, Frasdorf, Gstadt am Chiemsee, Höslwang, Prien am Chiemsee, Rimsting, Samerberg. Alle wichtigen Infos und weitere Details zu Rosi gibt es unter www.rosi-mobil.de oder telefonisch unter 08031/400 700. Die Mobilitätszentrale ist zu den Betriebszeiten von Rosi für dich erreichbar und steht für deine Fragen zur Verfügung. Übrigens: Ein Teil der Rosi-Flotte verfügt über Rollstuhlrampen und kann im Rollstuhl sitzende Fahrgäste mitnehmen. Bitte gib das im Bedarfsfall bei der Buchung an, damit ein barrierefreies Fahrzeug geschickt werden kann. Die Mitnahme von Kinderwägen und Buggys ist ebenso möglich. Für die Beförderung von E-Rollstühlen ist Rosi leider nicht geeignet. Auch größere Gepäckstücke, die über Handgepäck hinausgehen, Fahrräder oder elektrisch angetriebene Leichtfahrzeuge (sog. E-Scooter) können aus Kapazitätsgründen leider nicht befördert werden.

Verdict

The call

The clearest difference is ads: Rosi at none against Dott's shown. Rosi also leads on monetization model (free vs free with in-app purchases). Dott's advantage is ratings volume (9.4K vs 3) and update cadence (weekly vs fortnightly). On price, rating, in-app purchases and device support there is nothing between them.
