No doubt this is top security key storage. Can you give some insight how comfortable is to use it daily across different #nostr apps on mobile/desktop?

Look what I got in the post. The next generation of remote signer for NOSTR from nostr:npub10efcj7x65z2ak6vd69xr8f2hvqwuaqrhlygl3yqa4y63hfvc02mqwzaeh3

Not many apps support remote (bunker) signing yet, but a few do, like Coracle, Jumble etc...
I haven't started using this one in earnest yet, but I had the previous one, which I wrote an article on here:

If you're looking for a universal, complete, bug free solution, we are not there yet, but if you're interested in experimenting with a potential future direction for key security, then it's definitely worth playing with.
Thanks for report! Actually I was looking for ordering one but they are out of stock at the moment.
