I just spent 3 months in London, and it's crazy how Monzo seems to have taken the market. Almost everybody seems to be paying with a Monzo card, regardless of age. Asking around, I consistently heard that Monzo's competitors like Revolut are going to be a future case study in scaling before great product/market fit. I don't know how many people have Revolut accounts, but nobody seems to be using their cards in public…
I'd take another look at Simple. I've been with them since the beginning and their recent enhancements are fantastic! Expenses tied to your pay schedule that automatically set money aside, same with goals. and then the big one for me was an interest bearing savings account, yielding 2%.
