How much time do you think we have left?

Start a group

How it works

1. You get a private link. Send it to your friends.
2. Each person enters their email and sets four sliders.
3. Every change is timestamped, so the group's history is the interesting part.
4. When anyone updates, the group gets a push via ntfy — no account needed.
5. Once a month, and only if somebody actually moved, a digest email goes out. That's the only email this thing sends.
