> So which non-custodial LN wallets support NWC and zapping?

None.

NWC is a service that needs to run on a Linux server and listen for connections if you want to one touch zap.

For instance, full node bundles like Umbrel and Start9 have NWC docker installers that are pre-configured to connect to the included LND node.

You can't run a docker NWC with a Zeus LND node using neutrino on Android. Yet.

There's a couple of bounties available for both an android and an lnbits port of NWC.
