Kyna
Immediate feedback. Three scores.
Simple, easily interpretable feedback the second you rack the bar. Three numbers out of 100, each calculated against your own history - no biomechanics degree required.
There's more to your lifts than weight on the bar. Kyna unlocks the metrics that have been missing from your training.
Equipped with a suite of sensors that measure your performance, and paired with software that learns your unique style. Every athlete moves differently. Kyna picks up on yours and builds a baseline that's yours alone - so the feedback you get is yours alone too.
Pocket-sized and portable. Take it to any gym, garage, warehouse, or training facility - clip on, lift, get your scores. Your training travels with you.
Simple, easily interpretable feedback the second you rack the bar. Three numbers out of 100, each calculated against your own history - no biomechanics degree required.
Time-series data for medium-term review - force production, vertical acceleration, and the direction of force output at every instant of the lift. The view your coach has been waiting for.
Every lift, stored and searchable. Track improvement over weeks and months, see how your strength trends, and find the load you produce the most force with.
This example uses one real 180 kilogram back squat repetition from Kyna data, shown the way the app turns a set into scores, context, and next-step feedback.
Entire set · 1 repetition detected
Strong drive through this back squat. Peak upward acceleration reached 10.64 m/s^2, and the loaded barbell peaked at an estimated 3,680 newtons of applied force.
Feedback improves with more history. Record more back squat repetitions near this load to sharpen future comparisons.
Scores based on personal history would appear here once enough matching sets have been recorded.
Example feedback is static and for product demonstration only.
A simple interface that gets out of your way. Pick your exercise, hit record, get back to the bar.
Compare your output across loads, weeks, and cycles. The patterns are calculated against your own history, not anyone else's.
Repetition-by-repetition artificial intelligence analysis is in development. Our goal is the most intelligent performance tracker on the market.
Clip on. Lift. See your scores. No complex setup. No bulky equipment or calibration routine. You already use a collar - why not use Kyna?
A measure of how fast you moved the bar. One simple score is calculated based on the peak acceleration of each rep, compared to every other rep you've done. This is the cleanest single read on how hard you drove this rep.
Along with detailed, scrollable plots showing your acceleration at every instant of the rep.
How much of your effort traveled vertically, where it counts, versus laterally, where it doesn't. Deviation is wasted energy - and over time, an injury risk.
A key metric for true athleticism. Force production in three dimensions at every instant of the lift, derived from mass and acceleration. See exactly where in the rep you generated force - and where you stalled.
Detailed graphical views showing the direction of your force output at every instant of the lift.
Ten prototype devices are in the field with our first pilot users. The next batch is opening to beta sign-ups now.
