Challenges
Challenge yourself - and your friends.
When a challenge is live, join it from Improvement in one tap. Only the days after you join count, hit the target on enough of them, and you earn a badge plus a shareable certificate. No challenge running - the section simply isn't there.
A fixed window, a clear target, a badge at the end
Challenges sit on top of four programs - Movement, Sleep, Stress and Workout - each with its own kind of target.
Time-boxed, not open-ended
Every challenge runs for a fixed window, like 30 days. Join late and only the days from your join date count toward it.
One clear target
10,000 steps on 25 of 30 days. A steady bedtime. Calm on enough days. As many sessions as you can. Simple enough to just start.
A badge and a certificate
Meet the target before the window closes and you earn a badge plus a certificate you can share.
Race a friend, privately
Invite a friend to race inside a challenge. You both see progress counted against each other - never each other's raw readings.

Challenges track behaviour, not health outcomes.
Sam is a wellness app, not a medical device. A challenge measures whether you did the behaviour - steps, bedtime, calm minutes, sessions - not whether it changed a health outcome.
Common questions
What happens if I join a challenge late?+
Only the days from your join date onward count toward the target. Joining on day 5 of a 30-day challenge leaves you 25 days to qualify, not 30.
Which programs have challenges?+
Movement, Sleep, Stress and Workout. New challenges are published on a rolling basis, so what's live changes month to month.
What if no challenge is running?+
The Challenges section on Improvement simply isn't shown. New challenges are published periodically.
Can I race a friend?+
Yes - inside a challenge you can invite a friend to race. You both see progress counted against each other, never each other's raw readings.
Do I need a friend to join?+
No. Racing a friend is optional - every challenge works solo too.
What do I get for finishing?+
A badge for that challenge, plus a shareable certificate.
