Hope !

Hope! is a post-disaster emergency mesh communicator. When cellular and internet are unavailable, it relays SOS alerts and messages to nearby phones that also run Hope!—over Bluetooth and the same local Wi-Fi, without pairing.

Send a broadcast SOS with an optional location pin, exchange sealed private chats that nearby phones can hop but not open, and see nearby Hope devices while the app is open. Optional email sign-in syncs your profile and chats when connectivity returns.

Hope! is not a substitute for calling emergency services. Use every path to help that you have.
