I have both the Monzo prepaid beta and the Monzo current account preview.
I’ve just been abroad and one of the things that I noticed is that the Prepaid app send you a welcome SMS when you arrive in another country. It tells you what the conversion rate is.
When you return to the UK it gives you a summary of what you spent abroad.
This is all interesting and useful but the current account app does not do it. Perhaps that functionality will come in time.
Revolut sends a welcome SMS when you arrive in a new country. Starling does not …no chirps from that one.
