There is! Vgan. On Android at least. Costs a few bucks, but I find it useful. It pulls the data from barnivores website.

Looks like there are several more options for Barnivore than when I looked a few years ago.

Maybe where you live, but in the UK at least most draught bitters and ales will have fish or egg in it for filtering. Some of the bottled versions of the same beers are vegan. I always check with Vgan (or Barnivore.com if at home).

This already exists. It just uses the Barnivore database. Is that what you're using, too? Do you offer offline access?
Also yeah not showing as compatible with anything. I have more than one Nexus device on that list so that's definitely not a good sign.
I prefer Vgan, the interface is nicer. You do have to pay for it though.
