Comments on Postbank BestSign for Android

★★★★★ Jazent “9keys” · Mar 13, 2025

Well-developed apps, well secured very comprehensive to use and no glitches of any sort I must confess is quite nice and works very well.

★★★★★ Ileana Pinto · Nov 21, 2025

Very uncomplicated, easy and always working properly.

★★★★☆ Kornel Naruszewicz · Nov 20, 2024

The first thing you see is "relax nothing to approve" only to get the message that there is sth to approve one second later. Maybe you can fix it. Other than that okay

★★★★★ Yeshua loves us · Jul 12, 2026

I have learned to use online methods. First, I was furious 😠 but now am relaxed 😌

★☆☆☆☆ Mark Wilson · Oct 19, 2025

Forces phone restart! I know my ID but not my password so when I go into the screen to get my password, I enter two letters of my ID and then the app forces my phone to shut down and restart.

★☆☆☆☆ Ant Win · Dec 24, 2025

It keeps saying that the password is incorrect, but it's correct! Extremely annoying 😡

★☆☆☆☆ Xaris Admiral · May 28, 2026

Garbage, will rarely work on older phones. The app opens and closes by itself and the confirmation windows is gone. I have a samsung A14. You need a new phone with high ram for it to work reliably. Fix your application it shouldn't be this heavy and unreliable. I'm a developer myself. I know what im talking about.

★☆☆☆☆ Khaled Hijazi · May 5, 2026

Can't change app language, app adopts phone's primary language!! So let's say phone language is English, u cant set app language to German!!
