Offline messaging
Works where there is no signal
Phones connect straight to each other. No internet, no server, no account to set up. What you write stays between your phones.
- Mountains
- Festivals
- Abroad without roaming
- Long flights
- Underground car parks
- Boats
- Camps
How it works
-
One person becomes the Host
Their phone creates the network everyone else joins. Pick whoever has the most battery left.
-
The others scan a QR code
Bluetooth helps the phones find each other. The Host lets people in one by one, and the code is replaced after every join.
-
That is it
Write, send photos, drop pins on a shared map. None of it goes out to the internet.
If someone walks out of range, the app rebuilds the connection by itself once they are back. Messages sent in the meantime wait in a queue and arrive — even if a phone was restarted along the way. A group holds up to eight people.
What it does
-
Chat
Messages, photos, quoted replies, mentions, reactions, polls and private messages to one person.
-
Offline map
A world map ships inside the app and draws with no network. Download a detailed local map beforehand. The whole group sees the pins.
-
Position, for a while
You can show the group where you are — once, or for a stretch of time you choose, up to four hours. Then it switches itself off.
-
Translator
59 languages, entirely on the phone. It also translates whatever you point the camera at — a menu, a sign, a timetable.
-
Guide
Ask about the country you are in and the answer is built from a knowledge pack you downloaded before the trip — together with the passage it came from. All of it runs on the phone.
-
Long range
Contact further than Wi-Fi reaches, if you add a radio board of your own. In the field we measured over two kilometres in the open, and a few hundred metres with one end indoors.
-
Games
ColorMatch for the whole group, Battleships for two, Neon Merge for one. Everyone's scores land on a shared podium.
Why this is private
Not because we promise not to look. Because there is nowhere to look — there is no server for anything to pass through.
- There are no accounts We never ask for a name, an email or a phone number. We have no use for them.
- Traffic between phones is encrypted And it passes through nothing on the way.
- Your chat history sits encrypted on your phone Uninstalling wipes it for good. We hold no copy.
- You share your position yourself, and only for a while There is no “always on” mode: every time, you decide separately how often and for how long. Positions go to your group only and are never written to storage — neither yours nor anyone else's.
- No ads, no trackers The app contains neither.
The app reaches the internet only at home, before you leave: for maps, language packs and knowledge packs, and when you buy a plan. What exactly goes where is listed in the privacy policy.
What is free
Only the person who starts the group pays. Everyone else joins without buying anything, and without being checked for a plan.
