How does ChirpChirp work without internet?

ChirpChirp uses Bluetooth and Wi-Fi Direct to create a mesh network between nearby iPhones. Your messages hop directly from phone to phone -- no cell towers, Wi-Fi routers, or internet connection needed.

What is the range?

Device-to-device range is approximately 30-100 meters depending on environment. With mesh relay, messages automatically hop through intermediate devices. Five phones can cover roughly a kilometer.

Is it really encrypted?

Yes. All channel communication is encrypted with AES-256-GCM. Each device has a unique Ed25519 identity key stored in the iOS Keychain. There are no servers that could be compromised -- your messages exist only on the devices in the mesh.

Why does it need my location?

Location is used for sharing your position with nearby peers on the map and broadcasting your coordinates during emergency SOS. Location data is shared only with devices in your mesh -- never sent to any server.

Why does it need Bluetooth?

Bluetooth is used to discover nearby devices for peer-to-peer communication and to provide awareness of devices in your environment.

Does it work in airplane mode?

Partially. You need Bluetooth and Wi-Fi radios active, which can be toggled on separately in Control Center even in airplane mode. Cellular signal is never used.

How do I use push-to-talk?

Hold the large PTT button on the home screen to transmit your voice. Release to stop. Everyone on your channel within range hears you instantly.

What about battery life?

ChirpChirp uses Bluetooth Low Energy and Opus audio compression to minimize battery impact. Background mesh activity uses a minimal audio session to keep connections alive for emergency use.

How do I report a bug?

Email support@chirpchirps.com with a description of the issue, your iPhone model, and iOS version.
