I ended up going with MFP anyway because it had the most matches to my local produce here in Europe (the competitors I was considering all mostly had US stuff). It’s not perfect and the fact the food is user-submitted means you need to double check but it works good enough.

Anyway, from what I remember while there’s only direct integration with MFP, I do believe you can get it to work by going through a third party app that serves as a bridge, like Google health, the apple equivalent or I think there’s a few other non-FAANG options too.
