User Reviews

The reviews indicate the app is largely unusable: repeated login/OTP failures, sign-up errors, and persistent network message errors. Many users feel the service was devalued after rebranding to Dott, with some forced to switch apps. A few mention instability or crashes, and very few positive aspects are noted.

Pros

Some reviewers report the app is technically stable.

Cons

Frequent login issues and OTP delivery failures (OTP not arriving, login often not possible).
Registration/sign-up errors (unknown error; can't create account; 'unable to access the internet' messages).
App became unusable due to Dott integration/forced to use the Dott app.
Persistent 'no internet' or 'check your internet connection' errors despite a working connection.
App crashes or fails to start / navigation blocked.

I want my refund on the balance.

Seit Wochen kommt der Einmalcode (OTP) bei der Anmeldung oft nicht an. Getestet mit zwei Mobilfunkanbietern, zwei SIM-Karten und zwei Geräten. Andere Apps empfangen SMS sofort – nur hier nicht. Dadurch ist ein Login häufig nicht möglich. Die App wirkt stabil, aber ohne funktionierendes OTP ist sie praktisch nicht nutzbar. Bitte prüfen Sie die SMS-/OTP-Zustellung.
