How Kyniskis Works

A platform that reads your body — from the devices you already own — then tells you one thing every day: whether to push, hold, or recover. No new hardware required.

Your Devices + Our Intelligence

Kyniskis is not another band you have to buy. It's the intelligence layer on top of the wearables you already use — Apple Watch, WHOOP, Garmin, Oura. We aggregate the data, run our algorithm, and give you a decision.

📲

Multi-Device Aggregation

Connect Apple Health, Google Health, WHOOP, Garmin, Oura. Kyniskis pulls them into one unified picture — no lock-in, no new hardware. Your existing device is the best device.

🧠

Core Algorithm

Three dimensions — Recovery, Training Load (TLR), and Emotion — fuse into one Composite Score. It tells you whether you're ready to train, and how hard you should go today.

💬

AI Coaching

The score becomes a sentence: "Recovery is high, TLR is in range — push weight today." Not a dashboard. A coach. In English, Chinese, or Cantonese.

The Signals That Matter

Kyniskis reads the biomarkers that matter most for performance and long-term health — from whatever device you already wear.

😴

Sleep

Stages (REM, deep, light), efficiency, and consistency. Understand what truly restores you.

🔄

Recovery

A daily score of how ready your body is for physical demand — based on HRV, resting heart rate, and sleep quality.

🧭

TLR (Training Load Ratio)

Your acute (7-day) vs chronic (42-day) training load. TLR catches overtraining before you feel it — the ratio that tells you to add, hold, or back off.

💓

HRV

Heart Rate Variability — the gold standard for autonomic nervous system balance and recovery readiness.

❤️

Resting Heart Rate

A cardinal sign of cardiovascular fitness. Track it overnight and watch it trend lower as you get fitter.

🫁

SpO₂

Blood oxygen saturation during sleep. Early insight into respiratory trends and altitude adaptation.

🌡️

Skin Temperature

Nighttime temperature deviation from your baseline. A subtle but powerful signal of immune response and recovery.

🫁

Respiratory Rate

Breaths per minute during sleep. Changes can signal stress, overtraining, or the onset of illness.

Three Dimensions → One Decision

The magic isn't more data — it's the fusion. Three signals, each measuring something different, combine into a single actionable answer.

🔄

① Recovery

How recovered is your body? HRV, resting heart rate, sleep — the physiology of readiness.

🧭

② TLR

How much load are you carrying? Acute (7d) ÷ Chronic (42d) training load, effort-weighted.

🎭

③ Emotion

How do you feel? A daily pre-training check-in — fire, neutral, or drained.

How the Composite Score Is Built

🧭 TLR = Load Ratio

TLR = EWMA(7d) ÷ EWMA(42d)
Per-workout load = effort^1.5 × duration.
The 42-day chronic window (TrainingPeaks CTL/ATL standard) smooths out noise better than Apple's 28-day.

⚖️ Decision Split

TLR decides "how much."
Recovery + Emotion decide "can you even train?"
Two separate questions, one fused answer.

🎯 Output

A single Composite Score (0–100) with three visible sub-scores — Recovery, TLR, Emotion.
Transparent, not a black box.

Wake Up to a Plan, Not Just Data

Every morning, Kyniskis delivers one Composite Score plus a coaching sentence — telling you what to do with it.

🎯

One Score, Five Levels

Not a binary "good/bad." Kyniskis outputs five levels — high intensity, moderate, low, active recovery, or full rest — so there's always something useful to do today.

📈

Trend Analysis

Beyond daily scores, Kyniskis surfaces patterns: Is HRV trending down over a week? Is sleep debt accumulating? The app warns you before you hit the wall.

🗓️

Weekly & Monthly Reports

Automated summaries show progress over time. Compare training blocks, identify what works, and adjust your approach — all backed by your own data.

No Two Bodies Are the Same. We Learn Yours.

The first month is calibration. Kyniskis builds your personal baseline — because your "normal" is unique to you.

1

Day 1–3: Connect & First Data

Connect your Apple Watch, WHOOP, or Garmin. You'll immediately see your live heart rate, sleep, and activity — no configuration required. The platform begins learning.

2

Day 4–7: Early Patterns

With a week of data, you'll see your first Recovery and TLR scores. Your HRV baseline starts forming. The app begins surfacing correlations: "Your recovery is higher after 7+ hours of sleep."

3

Day 8–14: Baseline Solidifies

Two weeks in, your personal ranges for HRV, resting heart rate, and respiratory rate are established. Recovery scores become more precise. Daily coaching grows more personalized.

4

Day 15–30: Your Kyniskis, Calibrated

By the end of your first month, Kyniskis knows you. TLR targets are tuned to your fitness level. Recommendations reflect your chronotype. You're no longer guessing — you're training with clarity.

No New Hardware. Bring What You Have.

Kyniskis doesn't ask you to buy another gadget. It works with the wearables already on your wrist or finger.

🍎

Apple Health

HealthKit aggregation — the hub for Garmin, COROS, Amazfit and most other devices.
