No, it’s a full blown app. https://image.nostr.build/c6fca4c9f4042ff1b07717bef60f63bfc6763f07380b041ce5be8adcd30b28e4.jpg
WTF! Are you in the US? I’m in the US & the Alby app does not show up in the Apple App Store for me. I have to use a browser extension.
I am in the US so all I can think of is that I installed it a long time ago (before Alby did away with custodial stuff) and I turned off all auto updates on my iPhone.
