I was charged for a €133 for a 10 day bike ride. Even though the bike unlocked and I was able to ride it barely because the app did not mention it was damaged. I tried to go into the app to stop the ride and it told me no ride was active so I assumed maybe something didn’t quite register. Only to find out that I was charged FOR 10 DAYS!! I got no notifications or anything that the bike was still active except for a text on the 10th day. I also couldn’t just go back to the bike later because it was gone a few hours later. Because it was gone I assumed that someone else came along and purchased a ride. Horrible app and service! USE SOMETHING DIFFERENT!!

Argh
What a horrible first time experience. Here I stand for 10 minutes trying to set up a login, get a text password and on and on. No Apple Pay? Ok fine. But then there is no way to use iPhone’s system wide automatic system to enter my credit card information. So I have to go in and copy and paste. We are in 2026 now, auto-credit card is table stakes. Then, your password does not automatically get saved. Verify by text. Etc etc etc. I don’t know how easy this all is to write an app for, but it can’t be that hard, everybody else can do it. Reporting a unwelcoming tourist experience from Frankfurt here.

Deutliche Verbesserungen in der App
Ich bin mit den neusten App Version sehr zufrieden. Insbesondere die Anzeige-Aktualisierung der aktuellen Fahrt ist jetzt sehr zuverlässig. Was ich mir noch wünschen würde, wäre ein Bedarfs-Meldesystem für neue Stationen. Hier gleich ein Bedarf: Berlin, östliche Reichenberger Straße – große Lücke!

Hallo Corto4096, denke für dein ausführliches und konstruktives Feedback, wir schauen uns das gern näher an. Liebe Grüße, dein Call a Bike-Team
Neue Version wieder instabiler
Nach wie vor ist hervorzuheben, dass die Räder allgemein in gutem Zustand sind und die Rückgabe übers Schloss sehr zuverlässig funktioniert (was früher das größte Problem war). Version 7.6.6 läuft leider wieder deutlich instabiler. Das Ausleihe-Statusfenster oben fehlt meistens zunächst komplett und zeigt später nicht korrekt den aktuellen Status an (Standard/Geparkt/Zurückgegeben). Das lässt sich oft zurechtschubsen, indem ich den QR-Code nochmal scanne – das ist übrigens sehr bequem zum Entsperren des Parkmodus. Das Scanner-Fenster wiederum freezet gerne mal. Man muss also oft die App killen und neustarten. Gut ist, dass sie wirklich sehr schnell neustartet.
