So if I'm at the trucker protest in downtown Ottawa and they shut down the mobile network as long as someone is in range of available internet with BLE and this app with correct permissions my message can bonce from device to device until it hits a nostr node connected to internet. Alternatively if they cut my bank accounts and I loose internet or ability to pay people, I can still zap people on nostr and they can zap me! That is what I understood from it.
