in it’s base version, Revolut is free, yet they surely try to convince you to pay for a paid plan, use their depot, and other stuff… However the only downside worth mentioning is getting less interest on the savings account. Or did you refer to them being a UK bank? In that case: Revolut exists in multiple countries - my account is in Lithuania, yet still fully managed in €. They nowadays also have a german banking license (giving you a DE-IBAN). Accounts themself can be in on of, I dunno… 33 different currencies or so?

Another option worth mentioning would be Trade Republic, however I’ve never tried them myself.

I actually went with Revolut as my Bank, using their virtual credit cards for online payment - they offer a virtual one-time CC as well which details reset after each succesfull transaction. Thow way there’s at least no 3rd party besides CC provider and my bank snooping on my transactions.

You dont want/need root for graphene in the first place. that would just open another attack vector and is strongly discouraged.

+1 vor HeliBoard. I was in the same position and switched about half a year ago. The only thing I missing so far is a dedicated voice input button.
