FlowJitsu Keeps a Record of Every Roll

Field notes

The app records both whole sessions and individual rounds, including partners, submissions, notes, and what to drill next. Its technique library is described as containing more than 500 entries with belt, position, and gi/no-gi filters, while flow charts connect positions, transitions, and submissions into decision trees. The page also presents offline operation and cross-device synchronization, plus example counters for sessions, rolls, and mat time.
