Challenges
A challenge is a group of people, a metric, and a window of time. Invite by link, and everyone sees the same standings against the same rules.
Invite by link
An invite link opens and explains itself before anyone signs in, so the person deciding whether to join can actually read what they are joining.
The metric is stated up front
Sessions logged, volume, consistency — whatever the challenge counts is visible before you join, not discovered when you fall behind.
Questions
- Can I leave one?
- Yes, at any point.
