Everyone tracks the body. Kin adds mind.

Used by players and staff in

SHL · NHL · Premier League · Jupiler Pro League · Handbollsligan

Same body. Different game.

The difference was never in the body's data or the analytics. Kin captures what was.

Players, in their own words.

I'd have wasted five or six more games finding it myself. Now I only wasted one.

Calle Clang · Goaltender · AHL All-Star

My watch tells me my body is ready. It has never once told me my head isn't.

Linus Sandin · Ice hockey · Forward

Kin showed me I had performed on the days I didn't feel right physically too. Now I come to the game charged with confidence.

Ludvig Lindeberg · Handball · Left wing

They won it all. They still couldn't explain why.

I didn't win by raising my best day. I won by raising my worst. I trained to always find a mental advantage. Kin is that, every day.

Anja Pärson · Olympic champion · 7× world champion

I spent most of my career thinking about chemistry and momentum. I never figured it out.

Johnny Oduya · 2× Stanley Cup champion

I won tournaments and never knew why. Kin is how you find out.

Alexander Björk · DP World Tour winner

The diary that pays back.

Training diaries get abandoned because they give nothing back. Kin takes a minute, morning and after every session, and gives something back each time. So players keep coming, and Kin keeps learning them.

Our first cohort of professional athletes. Six months in. Players check in on 78% of days.

Backed by research

How players feel shows strain early.

56 studies: self-reports picked up training load more reliably than common body measures.

Life off the field counts.

19 studies: stress outside sport is linked to injury.

Elites reflect to perform.

Top runners plan, check in with themselves and review.

4Sports puts Kin in the hands of its players.

Sometimes you need a human voice to deliver what the AI found. That combination is unique.
