Android ยท Closed alpha

A summon is a place, a time, and a list of who is coming.

An app for small groups who arrange to meet in person. Someone drops a pin with a clock on it, the people in that circle answer, and the invite deletes itself when the clock runs out.

Summons

An invite with an expiry date

Set what is happening and for how long, anywhere from 15 minutes to 24 hours. Everyone taps going or passes. When the time is up it ends by itself and moves into the circle's history, so there is nothing to cancel and no dead event left in the chat next week.

On the way

Who is coming, and how far off they are

Say you are going and everyone else can see how much road is left between you and the place. Your phone does the maths and publishes one number: the distance. It sends us no coordinates and no route.

Not a countdown, deliberately. The same trip is eight minutes by car and thirty-five on foot, so a shared arrival time is wrong for whoever is not travelling the way it assumed. Metres are the same number however you cover them. It is a reading from when that person last checked, so it disappears after half an hour rather than going stale in front of you.

What the server holds for this summon: four usernames and three distances.

Consensus summons

When nobody can agree on where

Propose up to four spots instead of picking one, and let the circle vote. At the deadline the server decides, not your phone, and the winner becomes an ordinary summon.

Circles

Group chats that count who turned up

A group chat with one extra thing: a count of how many summons each person turned up to, visible to everyone in it. It is a count and nothing else - no score, no target, no league table.

Your data

What is stored, and in what form

Not everything here is encrypted the same way. One-to-one chats are end-to-end encrypted and circle chats are not: a circle is a group conversation we store in readable form, the same as any other. Your phone generates the keys for the private ones and never uploads them.

The privacy policy has the full version.

Summons open to people you don't know yet

Post a summon anyone nearby can find and join, rather than only the circle you chose. It is on in the Android app, and it will stay quiet until there are people near you using it.

A public summon never carries its real address. Strangers see a circle, and the true point sits somewhere inside it, equally likely to be anywhere. Our server widens that circle in emptier places, from 800 metres in a city to 5 km in the countryside, and hands out the exact spot only once you have joined. You must be 18 to use any of this.
