This app is really really Bad. Updates at least once per month, if there is a new one you have to install it or it won't work. Sometimes after a new update it just will not work anymore.. Sometimes I have to enter the payment Datas 4, 5, 6 times until it finally works. It crashes all the time! This is just humiliation ritual.. Avoid!

Hello John. Thank you for your feedback and please excuse the inconvenience caused. Frequent updates are needed to improve the app's functions and security 🛡️. We recommend activating automatic updates: open the Google Play Store app and go to the profile icon (top right) > Settings > Network preferences > Auto-update apps. Best, your UBS Team.

Apart from the spying permissions as view network connections, have full network access, calendar, location, microphone, and shared storage, already the registration fails. It blocks at one of the last steps. Same as the badly programmed Credit Suisse app that was - please correct me if I am wrong - apparently a Swisscom work.

I spent an hour trying to figure out how to make a bank transfer. With Revolut, it's three clicks and you can do it on weekends with no fees. With UBS, you practically have to wrestle with the system to discover that they don't accept transfers on weekends, and on top of that, they charge 5 CHF for bank fees plus "UNDEFINED TRANSFER FEES." What do you mean, undefined? Huh? Either you tell me what it costs, or I'm switching banks. This is just one of the many issues that ubs has. Dissatisfied >:(
