So as of right now there are only a handful of wallets that support NIP-57 (Zaps)

1. Strike

2. stacker .news

3. vida.page

4. Bitcoin Jungle

More wallets are adding NIP-57 support by the day it seems. As of right now WoS doesn't support Zaps but you can still tip with it & they're working on Zap integration so it's really just a matter of time before your wallet will be Zap functional if you're not interested in switching over wallets to any of the ones I listed above.
