Messaging on the trail with no signal
Check in with the walkers ahead, agree on a meeting spot or catch up around camp. Knit keeps the conversation close to the people on your trip.
Knit helps your party stay in touch when cell coverage drops away. Phones carry messages along a chain of nearby walkers, and optional Meshtastic radios can bridge longer gaps.
Use it for everyday coordination on the trail and around camp. For contacting rescue services, carry a satellite messenger or personal locator beacon separately.
Stay in touch along the trail
A party strung out along a trail is the obvious one. The fast walkers are ten minutes ahead, somebody stopped to deal with a boot, and nobody wants to walk back down to ask a question. If the group is spread across a few hundred metres with people at intervals, each phone relays for the others and the whole line stays connected.
Camp is the other one. A basecamp, a car park meeting point, a large group site — anywhere a cluster of people is milling around out of sight of each other, with no coverage worth using.
It also works on the way there. Coach trips, ferries, remote hostels, anywhere a group is together but the network isn't.
Extend the route as your group spreads out
One hop is the range of Bluetooth or Wi-Fi. Line of sight across open ground you might get a hundred metres or so; through a stand of trees, around a ridge, or with the phone in a pack, expect a lot less. Terrain is unkind to short-range radio in ways an open field never shows you.
Each nearby Knit phone can extend the route to the next walker. Keeping people within phone-radio range gives messages a path along the trail; a gap beyond that range needs another hop.
For longer gaps, put a paired Meshtastic board with each separated group. Short direct messages can cross the LoRa hop and continue to nearby phones over Bluetooth and Wi-Fi. The Nearby room travels too, as the same open broadcast. Group chats and photos use the phone mesh or optional relays. Terrain and radio setup determine how far that extra hop reaches.
Do not rely on this for
- Calling for rescue. Carry a satellite messenger or a PLB, and know how to use it before you need it.
- Reaching anyone outside your group. There is no mesh where there are no people.
- Solo trips. A mesh of one phone is not a mesh.
- Navigation or live tracking. Knit can send where you are as a one-off card from a chat's menu, but it does not put positions on a map.
- Anything where a message absolutely has to arrive. Short-range radio in real terrain is best-effort, and you should treat it that way.
Common questions
Can I use this instead of a satellite messenger?
Keep both for their own jobs. Knit helps you coordinate with people on your trip. A satellite messenger or personal locator beacon provides a separate way to seek help beyond the local mesh; Knit does not contact rescue services.
How far apart can we be and still message?
Phone hops typically cover tens of metres, and the people between you can extend the route. Trees, rock and how you carry the phone affect range. For longer gaps, pair a Meshtastic radio with a phone in each separated group. Those LoRa hops can span kilometres in suitable conditions, with nearby Knit phones sharing the connection.
Does it drain the battery?
Scanning for nearby phones costs power, so it uses more than an app sitting idle. On a multi-day trip treat it like any other radio: bring a battery pack, and switch the cellular radio off if there's no coverage to find, which usually saves more than the mesh costs.
Does it work with no SIM in the phone?
Yes. Knit needs no SIM, no account and no internet connection — an old handset with no service at all works fine as a mesh node, which makes a spare phone a reasonable thing to hand to someone in the group.
