I use it for small amounts. Also sometimes as a proxy when receiving lightning payments from random strangers to not dox pubkey of my node(s) to everybody. On my iPhone I have both WoS and Phoenix installed. And also Zeus connected to Alby for Nostr zaps (need to have separate wallet with small balance for that, as because Apple disallow direct zaps to notes I use Zapple Pay, which is app I grant permission to do payments on my behalf).
