Inviting people with an invite code

People join a circle with a 6-character invite code, or by scanning its QR code. The code is the same one every time you open the invite sheet — it is re-served, not regenerated.

Invite someone

1. Open Settings from the profile button on the map.
2. Tap Add people to Circle.
3. Tap Share invite to send the code, or let the other person scan the QR code on screen.

Join a circle

1. Ask whoever is inviting you for the current code.
2. Open Zeno24 and enter the code.

Or skip both steps: point your phone's camera at their QR code and it opens Zeno24 for you.

Replace a code that went somewhere it should not have

1. Open Settings from the profile button on the map.
2. Tap Add people to Circle.
3. Choose to replace the code and confirm.

A new code retires the old one immediately. Anyone you already sent the old code or QR to will not be able to join with it.

How long a code lasts

• It is valid for 7 days.
• It can be used by up to 20 people.
• It dies on whichever comes first: 20 joins, or the 7 days.

If a code does not work it has usually expired, been used 20 times, or been replaced by a newer one. Ask whoever invited you to open the invite sheet again and send the current code.
