Kokaru Up is our racket-sports sensor: it logs shots, impact, and swing speed at the wrist.
Kokaru Up is Kokaru's own motion sensor worn on the wrist to log your game (starting with paddle): detected shots, hardest impact, and swing speed, in real time.
It's a beta feature. It measures wrist motion, so its metrics are relative: it doesn't measure racket angle, force in Newtons, or spin. Available on the KR3 and KB8 plans.
