## What is Kin | Performance Intelligence?

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.


## Version history (last 5 releases)

### 2.0.10 — 2026-08-12

- Add a note to your session. After you log a session you can write what
it actually was, in your own words. It sits on that day in your diary,
you can edit it later, and Kin reads it at your next check-in.
- New: a glossary of every metric, under Support in My Kin.
definitions, and what a low or a high value actually means.
- Values with no reading behind them are hidden instead of showing
something that isn't there.
- Additional bug fixes related to your wearables

### 2.0.9 — 2026-07-03

Connect your wearable: a new Connected Devices section in My Kin links Apple Health and other trackers, so sleep, activity, and body data flow in automatically.
Sharper voice capture: spoken check-ins now transcribe more accurately.

### 2.0.8 — 2026-06-24

Back-fill any past day. If you miss a session, add it later. Your record stays complete.
Swipe between days in your Diary. Compare one day to the next without going back to the calendar.
Your sport, your words. Kin now names your competition the way your sport does: a Race, a Fight, or a Meet, not a generic "Game." It carries through everywhere in the app.
Insights have more room. Advice can run a little longer now, drawing on Kin's full library of performance and psychology principles.
Calmer, faster insight reveals. Cards appear one line at a time, steady instead of flickering.
Trend graphs tell the real story. A rest day no longer reads as a collapse, so your charts show what actually happened.
Plus some small features and bug fixes to elevate your experience

### 2.0.7 — 2026-06-08

Session feedback just got sharper. Insights now read deeper into your training and give you one clear thing to try.
Session insights follow the full insight shape: headline, summary, what it means, and one thing to try.
Your newest session leads the home screen after you log, so the feedback is right there when it matters.
The training calendar now shows what you trained, not just how it went. Icons for cardio, sport, and gym on each day, with games highlighted, so you can read your month at a glance.
Goal countdowns are now exact to the day. Pick a precise date and trust the count all the way down to "Today."

### 2.0.6 — 2026-05-28

Faster, more thoughtful daily insights that stream as they generate. Smarter pattern recognition, less repetition of what you already know. Fixed a sleep check-in time picker bug.
