Nelos
Stay connected, never lost.
Offline maps, team location sharing, messaging, and Need Help coordination for LoRa mesh devices.
Built for your team, off the grid
Nelos works over your own LoRa mesh — no mobile signal, no servers, no account.
Offline Maps
View your team on downloadable offline maps, even when mobile coverage is unavailable.
Team location sharing
See where your teammates are and share your own position with the people you choose.
Offline team chat
Message your group directly over the LoRa mesh when cell and Wi-Fi are out of reach.
Need Help coordination
Send a Need Help signal to your team to coordinate quickly when something goes wrong.
No account required
No sign-up, no profile, no social network. Just open the app and connect to your device.
Works with Meshtastic devices
Pairs over Bluetooth with Meshtastic-compatible LoRa nodes you already own.
Made for the outdoors
Hiking, camping, family trips, field teams, and group coordination when signal is weak.
An honest note on safety
Nelos is not a replacement for emergency services, satellite messengers, or professional rescue systems. It is a coordination tool for your own team when connectivity is limited. Always carry appropriate safety equipment and have a plan for contacting professional help.
