I started using Curve since I swapped to Graphene. Upsides: it’s not google and it works fine. Downsides: it’s a free as in beer app that (I assume) is selling my data.

I’ve read that Monzo used to have their own NFC payment app, but it looks like that isn’t around anymore and they just integrate with Google Pay now. If anyone knows more about it I would love to hear it.
