Nelos is an offline-first team communication and coordination app. It lets a small group send messages, share live locations on downloadable offline maps, track people, pets, and gear, and coordinate Need Help signals over a LoRa mesh network using MeshCore-compatible devices - without mobile signal, accounts, or servers.

No. Nelos is designed to work when cell and Wi-Fi are weak or unavailable. Your messages and locations travel over your LoRa mesh network, not the internet.

Yes. Nelos connects over Bluetooth to a MeshCore-compatible LoRa node, which handles the actual radio transmission. Without a compatible device, the app cannot send or receive mesh messages.

No. 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 way to reach professional help.

Nelos uses your location only to show your position and to share it with team members you choose. Location is not collected or stored on any Nelos server. It is transmitted over your own mesh network only when you choose to share it. See our Privacy Policy for details.

Only while Share Location is on and you are in a team. Your location then goes only to that team, over your LoRa mesh device, never to a Nelos server. In the background this also needs background location allowed (“Always” on iOS, “Allow all the time” on Android). Updates are periodic, not continuous real-time tracking.

The separate setting Keep GPS on in the background is off by default. It keeps GPS on with the screen locked: it records your own movement history on your phone, and your team gets more regular updates while you share. On Android you'll see a persistent notification while it runs. Turn off Share Location to stop sharing. You can turn either setting off any time in Settings, and keeping GPS on may use more battery.

Nelos runs on iPhone, iPad, and Android phones and tablets, and connects over Bluetooth to a MeshCore-compatible LoRa radio. If you're unsure whether your radio is supported, email support@nelos.app with the model and we'll help.

Free keeps one team active at a time. With Nelos Pro, several teams stay active at once; everyone shows up on one map and you get a filter to hide or show each team. Each team has its own chat and its own encrypted channel.

Open the Nelos Pro screen in the app and tap Restore Purchases, using the same App Store or Google Play account you bought it with. If it still doesn't activate after a few minutes, email support@nelos.app with the store you bought from (App Store or Google Play) and the support code shown on the Nelos Pro screen.

You can send feedback and diagnostic reports directly from within Nelos. Diagnostic reports include relevant device and application information to help us investigate issues faster.

You can also email support@nelos.app. Including your device model, operating system version, Nelos version, LoRa device model, and steps to reproduce the issue helps us investigate faster - a bug report template is below.
