The short answer
On a camping or hiking trip where signal is weak, a child's
phone or a device clipped to the dog still works out its
location from GPS, but apps like Life360 or Find My need the
internet to get that location to your phone. Lose mobile data
and Wi-Fi and those apps stop updating, and you only see the
position from the last time there was a connection.
Nelos fills that gap. Parents carry a handheld device paired to
a phone over Bluetooth, a child or pet carries a small tracker,
and those devices exchange locations directly with each other
over radio instead of over the internet - free to start using.
Range depends on terrain, and this doesn't replace an adult
keeping an eye on a child directly.
Why the location "freezes" when you lose signal
GPS and the internet are two different things. GPS is a phone
or a tracker listening to satellite signals and working out
coordinates on its own; that doesn't need cell service. The
internet is the channel that carries those coordinates from
one device to another.
Life360, Google Maps location sharing, and most similar apps
send coordinates over the internet. When the group drives
into a valley or into the forest and loses signal, those apps
have no route to send a new location. The device still knows
where it is, but that information stays on the device. The
guide
Does Life360 work without signal?
goes deeper into this point.
Apple Find My is a bit more nuanced: an Apple device with no
connection can still be picked up by other nearby Apple
devices over Bluetooth and have its location reported. That's
useful in crowded places, but at a quiet campsite, with no
other devices around, it has almost nothing to work with.
Trackers: kids don't need to carry a smartphone
For young children or pets, carrying a phone usually isn't
practical. A small LoRa tracker solves that. It's a
battery-powered device with GPS that reports its own location
over radio without a phone attached. You can put it in a
child's backpack or clip it to a dog's collar.
A tracker doesn't message and has no screen. It does one
thing: it lets people in the group who carry a Nelos device
see roughly where it is on a map. So you still need at least
one adult carrying a handheld device paired to a phone, to
see locations and communicate with the rest of the group.
The Devices page lists
compatible trackers and the handheld devices that can double
as one.
If a child or the dog isn't where you expected, Nelos can do more than show the last dot: Find Mode asks the tracker for fresh positions much more often while you go and look, and a Safe Zone drawn around the campsite alerts your phone when a tracker leaves it. For the dog specifically, see tracking a dog where there's no coverage; for choosing a child's tracker, see what parents should know about kids' GPS trackers.
LoRa and Nelos: a backup location layer for the group
Nelos is an app that runs on top of LoRa radio. A parent's
phone connects over Bluetooth to a LoRa radio device. Instead
of sending data over the internet, Nelos exchanges the
group's messages and locations over that radio layer. No cell
service, no Wi-Fi, no account.
On screen, you see the most recent position each member and
each tracker has shared, on a map. This isn't continuous
real-time tracking the way it is with a connection; positions
update at intervals, and only while the radios can still
reach each other.
Range depends on terrain
There's no single range number that's right for every trip.
LoRa radio works best when there's a relatively clear path
between two devices. Terrain, trees, a hillside in the way,
antenna placement, and weather all affect how far a signal
carries. At a flat campsite, the whole family is usually
comfortably within range of each other. If a child runs down
into a deep gully or over the far side of a hill, the
connection can weaken or drop.
A mesh network can extend the coverage area
Out of the box, each radio talks directly to the others in range. To bridge points that can't reach each other - a child down by the stream, parents up at the tent - you can place a repeater somewhere high, on an outcrop or near the central tent, and messages and locations pass through it. Some compatible radios and trackers can also be switched to relay for nearby devices, at the cost of more battery. The guide Range and terrain covers this in more detail.
Download offline maps before the trip
A location dot on a blank screen is almost useless. For a
child's or a dog's location to mean anything, you need a base
map showing the trails, streams, and roads around it.
A phone doesn't come with a detailed map of a forest unless
you download it in advance. While you're still at home or
still have signal, download
offline maps for the
whole trip area, not just the campsite. After that the map
still works without the internet, and locations shared over
LoRa show up on top of it.
Example: a family on a weekend camping trip
Two parents, two kids aged eight and ten, and a dog. They
drive to a campsite in the forest, about forty minutes from
the nearest town.
On the way, the whole family has Life360 location sharing on
as usual, and the grandparents at home can follow along.
About fifteen minutes before they arrive, the road into the
forest loses signal. From that point, the location on Life360
stops.
At the campsite, each parent carries a handheld device paired
to a phone. Each child's backpack has a small tracker, and
the dog's collar has another. When the kids go collecting
firewood around the site and the dog roams about, the parents
look at their phones and see four dots moving around the tent
on the offline map they downloaded beforehand.
In the afternoon, one child follows a trail down toward a
stream. As they drop lower and disappear behind an outcrop,
their dot on the map updates more slowly, then stops. One
parent walks down the trail in that direction; when they're
back within radio range, the dot reappears, a few dozen
metres from where it last stopped. Nothing here replaces an
adult going with the kids - it just helps you know which way
to walk.
When the family drives back out and picks up signal again,
Life360 syncs and the grandparents at home see the new
location.
A simple setup for one trip
A compact arrangement for a family:
- Each adult: a compatible handheld device, paired to a phone over Bluetooth, running Nelos.
- Each child and each pet: a LoRa tracker, in a backpack or clipped to a collar.
- All devices in the same team in Nelos, checked before leaving home.
- Offline maps for the whole area downloaded on the adults' phones.
- Everything charged the night before.
The Getting Started page walks through pairing devices and creating a team. It works with a single adult too; if the group regularly spreads beyond direct radio range, a repeater placed high near the campsite helps more than extra handhelds.
Safety notes
A tracker tells you roughly where a device is. It doesn't
tell you whether the child is okay, whether they're still
wearing the backpack, or whether the dog is still wearing the
collar. A dead battery, a device that falls off, or terrain
blocking the signal all cause the dot on the map to stop
reflecting reality.
For young children near streams, cliffs, roads, or
unfamiliar ground, no device replaces an adult being within
sight and reach. Treat this location layer as a tool for
coordinating when the group spreads out a little around a
campsite, not a reason to relax supervision. Nelos isn't a
rescue device and doesn't replace a dedicated satellite
communicator for a genuine emergency.

Conclusion: internet when you can, LoRa when you need it
When there's signal, Life360, Find My, and similar apps do
their job well, including for grandparents following along
from far away. When the family goes into an area with no
connection, a LoRa layer keeps the parents seeing the
relative position of the kids and pets, as long as the radios
can still reach each other. The two layers don't conflict;
each covers what the other can't reach.
If your family regularly goes on outdoor trips into
weak-signal areas, Nelos is one way to add a direct location
layer between members and devices over LoRa.
Frequently asked questions
Does a LoRa tracker need a SIM or an account?
No. It communicates directly with the other devices in the
group over radio, doesn't use cell service, and doesn't need
a service subscription.
Do kids need to carry a phone?
No. The tracker reports its own location. But you need at
least one adult carrying a handheld device paired to a phone
to see the locations on a map.
Does Nelos track a child continuously in real time?
Not exactly. Positions update at intervals and only while the
radio connection holds. It's a coordination tool, not a
safety monitoring system.
Can a tracker replace watching a child?
No. It tells you where a device is, not whether the child is
safe. An adult still needs to supervise directly.
How far does it reach?
There's no fixed number. It depends on terrain, hardware, antennas, and radio conditions. At an open campsite the whole family is usually within range of each other; blocking terrain reduces the range, and a repeater placed high up can extend the coverage area.
