I get the iOS notification instantly when I pay for something with the card, whether in person or online.

Is this something more? (I'm a potential adopter if so)

1) good fx rate, I think it's google exchange rate with no fees for converting from/to various currencies

2) really easy transactions between friends (makes it really easy to settle up our holiday bills, could have an integration with Splitwise...)

3) almost instant feedback in the app about purchases

4) really nice analytics

5) virtual (unlimited?) cards, each with their own limit: I have a virtual card for my online purchases and my physical card has online purchases disabled

6) despite what others said, I've found the customer support to be all right

7) traveling insurance

8) (don't remember the exact amount) cheap-ish device insurance (eg for my phone)

9) metal card (as in, not a piece of plastic)

10) accounts in a shitload of currencies (used gbp, euro and usd so far)

11) contactless (but well, all cards seem to be like that)

12) (not using this) one can buy crypto coins via the app

Edit: It seems the functionality is there, but it doesn't work for Contactless, which is the majority of transactions I've done.
