I looked at lndhub as well.. too limiting and too specific for my taste. This NIP approach can standardize the API for all types of ln nodes.

By the way, I tested Nostros today (I installed it from the APK 3-4 days ago). Yes, there is a Wallet section there. But it doesn't work! You specify the lndhub URL, Nostros "accepts" it (after pressing the "Connect" button, it goes back to the Wallet screen), but nothing happens and after that everything looks like it didn't specify anything. I even thought that I might be pointing in a different format - but in a different format, it doesn't even allow you to exit using the "Connect" button. I even thought that maybe Zaps work after that - but no: with each zap, a QR code appears for payment. A very raw and broken application is this Nostros. I don't understand your admiration for him.
