PixLab FAQ
Is PixLab free?
Yes, PixLab is completely free and it doesn't have any in-app purchases or subscriptions.
Is PixLab legit?
⚠️ The PixLab app has poor ratings and negative feedback. Users seem unsatisfied with its performance or features.
No matter what I try I cannot receive the verification SMS using my Czech phone number.
Also, the registration process is incredibly cumbersome. If the intention was to block tourists from cycling in London then very good job.
Awwwful app!!!
Just spent 10 minutes trying to set up an account. Falls apart after confirming payment in my bank app every time.
so-so
Cumbersome app, when trying to rent, app said no bike available at location yet still charged for rental
Charged the money
Only one star and i really didn’t recommend it. When i tried to create the account the app charged me the money (twice) and i cant sing in.
Bug Issues
This app has multiple bug issues and multiple times the app has crashed or error sign. I use the latest iPhone with ios 18 and still has alot of issues.
App crashes
Doesn’t even work. Crashes on iphone so would have given it a zero rating.
Do not work properly
Do not work - I cant login, cant hire a bike - blank page
Not working whenever I’m out and about
Today I was met with a fun completely white screen when I chose which fare I want. Usually I am logged out or my payment details (why on earth you can’t use Apple Pay) don’t work either. Unreliable and not user friendly.
This app does not even run natively on larger screens
It seems this app has not been updated seriously in ages. It had the form factor of an iPhone 8 (2018). Why can it not display in full resolution in an iPhone 14?
The app crashes all the time
I have been using this app for a while now, but it recently started having issues. The app doesn’t open
