A wearable that learns your body — then coaches you to perform at your peak. 24/7 monitoring. AI-powered insights. Built for the modern athlete who refuses to accept limits.
Kyniskis is a system: a lightweight wrist-worn sensor paired with an intelligent mobile app. Together, they turn raw biometric data into a clear, actionable daily picture of your health.
Worn 24/7 — during training, work, and sleep. Continuous optical sensing captures every beat, every breath, every recovery cycle. Even charges without interrupting data collection.
Advanced algorithms learn your personal baseline and deliver daily, personalized recommendations: how hard to train, when to rest, and what your body needs today.
Track trends over weeks, months, and years. See how lifestyle choices, training decisions, and seasonal patterns shape your healthspan — not just your lifespan.
Kyniskis captures the biomarkers that matter most for athletic performance and long-term health.
Stages (REM, deep, light), efficiency, latency, and consistency. Understand what truly restores you.
A daily score indicating how ready your body is to take on physical demand — based on HRV, resting heart rate, and sleep quality.
Your daily physical load on a 0-100 scale. ThresZone quantifies how much adaptive stimulus you applied today — the exact dose your body needs to stay in the growth zone without tipping into overload.
Heart Rate Variability — the gold standard for autonomic nervous system balance and recovery readiness.
A cardinal sign of cardiovascular fitness. Track it overnight and watch it trend lower as you get fitter.
Blood oxygen saturation during sleep. Early insight into respiratory trends and altitude adaptation.
Nighttime temperature deviation from your baseline. A subtle but powerful signal of immune response and recovery.
Breaths per minute during sleep. Changes can signal stress, overtraining, or the onset of illness.
The space between comfort and overload — where real adaptation happens.
Your body needs daily stimulus. Not punishment — stimulus.
A precisely calibrated signal that tells your neuroendocrine system: adapt.
When you train inside the ThresZone, your hypothalamus and pituitary respond.
Cortisol stays in rhythm. Testosterone and growth hormone release at the right time.
This is the neuroendocrine balance that keeps you burning fat efficiently, recovering fully,
and building strength year after year.
Increase the load. More kilos on the bar. Your threshold expands when you prove to your nervous system that it can handle more.
Same weight, more reps. Same reps, less time. Your body learns to produce more power with the same fuel.
Extend the work. More rounds, longer sessions. Your aerobic engine grows when you ask it to sustain output over time.
Cardiovascular Load — time spent in heart rate zones, weighted by intensity
Movement Volume — accelerometer data capturing all activity, not just workouts
Daily Baseline — calibrated over your first 30 days of wear
A hyperbolic tangent (tanh) scaling model converts raw load into a 0–100 score.
Unlike logarithmic scales that lock at the top, tanh allows smooth progression into higher ranges —
easy to start, increasingly difficult to push further, never impossible to reach.
A single 0–100 score that tells you exactly how much adaptive stimulus you applied today.
Paired with your daily Recovery, it tells you which lever to pull — weight, efficiency, or lean back.
The rule: push one lever at a time.
If you add weight, don't also chase speed. If you extend duration, back off the load.
The three variables constrain each other. Your job is to keep the body guessing —
always at the edge of what it can handle, never beyond what it can recover from.
Push weight. Your nervous system is ready for heavy loads.
Chase efficiency. Speed and volume without adding load.
Skill work, mobility, active recovery. Don't push — prepare.
Every morning, Kyniskis delivers three key numbers — Recovery, ThresZone direction, and Sleep Performance — plus a concise coaching message that tells you what to do with them.
Not just a number — a direction. Based on your recovery, Kyniskis tells you which lever to pull today: weight, efficiency, or lean back. Stay inside the ThresZone and let your neuroendocrine system do the work.
Beyond daily scores, Kyniskis surfaces patterns: Is your HRV trending down over a week? Is your sleep debt accumulating? The app warns you before you hit the wall.
Automated summaries show progress over time. Compare training blocks, identify what works, and adjust your approach — all backed by your own data.
The first month is calibration. Kyniskis builds your personal baseline — because your "normal" is unique to you.
Put on the band and go about your life. You'll immediately see live heart rate, step count, and your first sleep report. The band begins learning — no configuration required.
With a week of data, you'll see initial Recovery and ThresZone scores. Your HRV baseline starts forming. The app begins surfacing correlations: "Your recovery is higher on days after 7+ hours of sleep."
Two weeks in, your personal ranges for HRV, resting heart rate, and respiratory rate are established. Recovery scores become more precise. Daily coaching recommendations grow more personalized.
By the end of your first month, Kyniskis knows you. ThresZone targets are tuned to your fitness level. Sleep recommendations reflect your chronotype. You're no longer guessing — you're training with clarity.
Lightweight, waterproof, and built for continuous wear. Kyniskis Band is engineered to stay on — so you can focus on living.
Full charge lasts up to 14 days. No daily charging, no performance anxiety — just wear it and forget it.
Swim, shower, freedive, sweat. Built for athletes who don't stop for their gear.
Under 25 grams. You'll forget you're wearing it — until you check your scores.
Efficient, secure sync with iOS and Android. No Wi-Fi chip needed on your wrist.
Health data is the most personal data there is. We treat it that way.
We built Kyniskis to improve lives — not to build a surveillance business. Your wellness data is stored securely, encrypted at rest and in transit. We believe health insights should empower you, not expose you.
