What is Flaresat?
Flaresat is a real-time collaborative mapping app for teams that need to stay coordinated in the field. Whether you're running an event, a search and rescue operation, a hike, or any situation where knowing where your team is matters — Flaresat keeps everyone on the same map.
What you can do
Drop pins, draw routes, and mark areas Place annotations on a shared map that every teammate sees instantly. Mark a rally point, outline a search zone, trace a patrol route — it all syncs live.
See your team's live locations Each member can opt in to share their GPS position. Everyone with location sharing on shows up as a labeled dot on the map in real time.
Chat in context Send text messages and voice notes directly inside the app. No need to switch to a separate messaging app — your communications are attached to your group.
Work completely off the grid
Connect a Meshtastic LoRa radio device over Bluetooth and create an off-grid group that operates with zero internet or cell service. Pins, routes, and messages travel over the mesh network, potentially miles away. Back up your off-grid group to the cloud or export it as a .flaresat file at any time.
Bridge off-grid and cloud teams with Relay Link an off-grid Meshtastic group to a cloud group and all activity syncs automatically in both directions. Mesh teammates and internet-connected teammates share the same map in real time.

Key concepts
Groups are the core unit of collaboration. You create a group, invite teammates with a code, and everything — the map, chat, and location feed — is shared within that group.
Cloud groups sync through the internet. Use these when your team has cell or Wi-Fi connectivity.
Off-grid groups work without any internet connection, using Meshtastic LoRa hardware to relay data over radio waves.
