Jitsuno

Jitsuno is the training log built for jiu-jitsu, not adapted from running apps. Log every session in seconds, see your submissions, taps and sweeps over time, and watch your technique map light up as your game grows. The app takes its colour from your belt and keeps the stripe count on your home-screen icon, so a promotion shows everywhere. Coaches run the gym's schedule from one place, with classes that can have different times on different days, and members check in, chat, and chase shared challenges. Dark by design, made for the mat.
