The shared connection
What it is
Whoever has Wi-Fi carries to the internet, within seconds, the messages of people nearby who have no signal.
Why it exists
Nobody is always connected. Today you carry someone else's message, tomorrow someone will carry yours. There's no prize and no ranking: people share because only by sharing, with no one-sided advantage, do both sides benefit.
How it works for you
It happens by itself when you're on Wi-Fi. In the Network tab you can see how many people you're sharing your connection with.
What you give
A small part of your Wi-Fi: about 1 KB per message, within a daily limit you choose (50 MB by default).
What you get
The same connection when you're the one without it.
What you choose
The daily limit; whether to also share your mobile data (off by default). Your own messages always go out.
Honest limits
The messages you carry are encrypted: you can't read them, and nobody can read yours. An SOS always goes first.
Where it stands
Tested in simulation with the full app and on a real server.
