App never opens

Whenever I try to login into this app, I always receive an error message saying I can’t access the app and should try after some time. If I try multiple time my account gets blocked for a few hours. Most frustrating experience!

One of the best banking apps

And most secure and user friendly, straightforward banking apps I ever used. Congratulations to the developers!

Only sorry that their sister app “safe” is only available to Swiss residents!

Horrible UI/UX

Possibly the most poorly built banking app I have encountered. All the most important information and functions (eg IBAN, Transfers) are a pain to do. This is a 300 year old wooden boat in an ocean with Virginia class submarines in terms of apps.

So bad it makes me want to change banks

so bad it makes me want to leave UBS after I was forced to migrate from CS. This app is the slowest banking app I have ever used (have had over 7 banking apps from Canada and Europe) and not as user friendly as Old CS one. Please fix the speed it’s wasting everyone’s lives, maybe ask the old CS developers?
