RallyMesh is an offline, bluetooth group chat that works without internet.

Messages hop from phone to phone using Bluetooth and nearby connections.
Stay connected at festivals, on trips, or when the network is down.

How it works:

* Pick a display name and group name.
* (Optional) Add a password. When set, messages are encrypted. Without one, they’re unencrypted and visible to anyone in the group.
* Your phone also helps relay other people’s messages to keep the mesh flowing.

Why it’s different:

* Internet-free: works entirely via nearby devices.
* Simple privacy: encryption automatically turns on when you set a password, and off when you don’t.
* Unique tag: a short device ID appears next to your name so friends know it’s you.
* Crowd-ready: messages can hop across multiple phones.
* Friendly defaults: clean design, clear status, and helpful tips.

Features:

* Group chat with direct and relayed messages.
* Message status indicators: sending / sent with timestamps.
* Modern, simple interface and Instagram-style settings.
* Optional background support so messages can keep moving.
* Start-at-boot option to stay ready after restart.

Permissions and battery:

* Uses Bluetooth / Nearby Devices to connect with others.
* Background activity is optional but improves message flow.
* Battery optimizations may limit relaying; you can manage this in settings.

RallyMesh is designed to feel intuitive for everyday users while staying reliable when connectivity is limited.

Say hi to your group and let the mesh do the rest.
