Health & Fitness

Turn habits into proof, not streaks.

A streak counter only shows that you tapped a button. Here, someone who saw the work confirms it.

Sample: what a finished Trophy Case looks like

The cost of doing nothing

Habit apps count taps, not results.

Streaks reset and prove little.

Nobody checks what really changed.

Motivation fades without a record that means something.

Build a record someone confirmed.

What you get

Questions

Is it free?

Yes. Paths, outcomes, proofs, verification and your Trophy Case are free. The paid Arena, doing this Portfolio with a group and weekly challenges, costs $5 or $12 a month depending on your country. Cancel anytime.

Who confirms my work?

People who saw it: a teacher, a client, a coach, a manager or a teammate. Some milestones are checked automatically first, against GitHub, a live site, a Google Doc or an official rating, once you link the account. Every confirmation is signed with a Proof Seal.

Is my health data public?

No. Clinical health proofs are always private, and health proofs are never shown to visitors who aren't signed in.

Does an AI decide whether my work is verified?

No. People and machine checks decide. For an adult's public code, an AI gives feedback and must quote the code it judges. Work by anyone under 18 is never sent to an AI.

Do I keep my proofs?

Yes. They belong to you and stay on your Trophy Case, with a seal anyone can check.

What is the Health & Fitness Portfolio?

The Health & Fitness Portfolio gathers the Powstik paths and outcomes that fit that goal. You do real work, get it checked, and share one link.

Who is it for?

It is for people who want to build a Health & Fitness record with real work. You pick the paths and outcomes that fit your goal.

What costs money?

Arena, the paid plan with teams and a league, has a monthly price shown on the Join button. Paths, proofs, checks and your Portfolio link have no charge.

How does verification work?

A real person who knows your work signs in and checks each proof. You can never check your own proof. Paying for Arena never skips this check.
