Built by elite athletes, for elite athletes.
Kin shows what drives your performance.
Kin is a performance intelligence system built to understand what actually drives your performance.
Originally developed with elite athletes, Kin combines daily reflection with physiological data to reveal the patterns behind your best and worst days.
So you can stop guessing and start making better decisions.
How it works
1. Daily performance check-in
Log how you felt, performed, and recovered in under a minute.
2. Connect your data
Sync sleep, recovery, and training from your wearables.
3. Reveal your patterns
Kin analyzes the relationship between how you feel and how you perform.
What makes Kin different
Most apps track metrics.
Kin connects:
• How you feel
• What you do
• How you perform
Then turns it into clear, actionable insight.
What you get
• Personal performance insights based on your real data
• Pattern recognition across recovery, stress, training, and habits
• Daily guidance tailored to your current state
• A system that gets smarter over time
Built from elite performance
Kin started with professional athletes.
The goal was simple:
Understand what actually leads to consistent high performance.
That same system is now available to you.
For two use cases
• When performance feels inconsistent and you don’t know why
• When you want to reliably replicate your best days
This is not another tracking app.
This is the system that helps you understand yourself.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Sleep on the check-in now reads in hours and minutes. A one-minute change to your wake time used to vanish on the old display. It holds now.
Logging a game takes you straight to its read.
Tapping the weekly notification opens that week's read, not just the app.
Sheets close with the same motion they open with, and the Today chart holds its place while it loads.
