I have it running in a browser on my MacBook. It runs a service worker in the background so it’s not necessary to keep your nsec.app dashboard open, but I usually keep itn open during the initial connection. You can run it on your iPhone browser, but I haven’t tried it. Talk to nostr:npub1xdtducdnjerex88gkg2qk2atsdlqsyxqaag4h05jmcpyspqt30wscmntxy
