How is it different from taking notes?
FlowJitsu is purpose-built for jiu-jitsu: a searchable technique library, interactive flow charts, belt progression, roll and submission stats, and training insights you can't get from a plain notes app.
“I built FlowJitsu because I wanted a better way to track my own jiu-jitsu. I make it in my spare time, and it's free — if it helps your training, that means everything.”
— Jeremiah Parrack, solo developer & jiu-jitsu practitioner
