You should be able to zap from wallet.cashu.me with no problem. It handles both ecash and Lightning seamlessly. And it has NWC so you can plug it in to your nostr client to execute zaps.

I just tested Cashu Wallet and it worked fine. I just plugged in the NWC connect string, and zaps worked as intended.
Alternatively, if you don't want to use a web wallet, you can download and use Minibits Wallet. It has the same functionality; supports both ecash and Lightning, and provides NWC support. I primarily use Minibits Wallet, and it's been a great experience.
i forgot minibits existed! i’ll try
nvmd :/ it’s not on ios
