Great idea but wrong data

Temperatures are wrong, eg. 19 degrees instead of 26 which make a huge difference for swimming. And app indicates high waves for a lake that is perfectly still.

Response from developer

Thank you for your feedback. Our water temperature data is based on measurements from water buoys, while wave data comes from a third-party provider. Please contact us and let us know the name of the location. We will investigate the data chain and work to correct any issues.

Слишком устаревшие и не актуальные сведения о температуре воды!!! Слабо, очень слабо…

Response from developer

Thank you for your feedback. We’re sorry to hear that the temperature data did not meet your expectations. Could you please tell us which location or measurement point you are referring to? We would be happy to investigate the data source and improve the accuracy if needed.

Hilfreich

Wenn man Wassersport macht ist man oft auch in wechselnde Gewässer unterwegs. Also war ich auf der Suche nach einer App die nicht nur Flüss, Meere auf dem Radar hat sondern auch Seen. Damit bin ich dann bei der App hier gelandet.
Ich finde sie persönlich sehr hilfreich da man so für die geplante Aktivität (sei es schwimmen, Paddeln u.s.w.) eine Möglichkeit hat bevor man am Wasser ankommt die Temperatur zu erfahren. Damit hat man dann auch eine Hilfe für z.B. welches Equipment (z.B. Trocken oder Neopren Anzug u.s.w.) benötigt werden.
Naive die Empfehlung für die Aktivitäten ist hilfreich, wenn man beachtet das jeder eine andere persönliches Empfinden für Sicherheit und Risiko hat, und das es nicht dem eigenen immer ähnlich ist. Somit mag es dem einen sicherer vorkommen und den anderen nicht. Das liegt aber daran das bei den Aktivitäten Empfehlung die User mit einen Einfluss durchs abstimmen haben.
Wer vor Ort die Empfehlung in der Aktivitäten prüft und dann für sich selbst entscheidet und anpasst, wird festgestellt das hilfreich ist vorab schon mal eine grobe Information zu haben.
Für mich ist die App sehr hilfreich und vor allem weil man mehrere Gewässer unter Favorisierten Speichen kann um es leichter zu haben. Und bei den Temperaturen passen die Angaben, was das wichtigste bei mir war.

ads are annoying!

Embedded ads are too much!!

Response from developer

Thank you for your feedback. We try to keep ads as minimal as possible while supporting server and data costs. We will continue improving the app experience and ad balance in future updates.

Zusatzinfos sind nicht immer korrekt

Die App ist im Ansatz gut, jedoch die Zusatz Informationen sind nicht immer korrekt und können für Nutzer sogar recht teuer werden. Zum Beispiel der Werbeliner See südlich von Delitzsch - hier wird, laut App, baden, campen und Wassersport angepriesen - das ist hier aber alles strengstens verboten, da das ganze Areal Natur-und Vogelschutzgebiet ist. Bei einer dementsprechenden Feststellung durch die Naturschutzbehörde oder die Polizei wird es richtig teuer, was aber richtig ist, denn solche Gebiete sollten unbedingt beachtet und geschützt werden!
