RollData vs Jits AI

Jits AI is an iOS-only BJJ app built around short voice recaps that an AI coach turns into written debriefs, plus a weekly technique focus and gamified streaks, XP and leaderboards. It is paid only, with no lasting free tier: $39 a year direct after a $1 seven-day trial, or $14.99 a month through the App Store.

Key Differences

Jits AI's voice-first logging is genuinely fast: a short spoken recap after class becomes an AI-written debrief, backed by a weekly technique focus curated from an IBJJF world champion's coaching and gamified streaks, XP, missions, and leaderboards that make consistency feel like a game.

RollData logs each round with structured technique, position, and outcome fields instead of a spoken summary, so your data stays queryable and comparable across your whole career rather than living inside short AI-generated recaps. Every core logging feature is free indefinitely, with no trial clock running out.

RollData runs as a responsive web app in any browser, so Android users, whom Jits AI's iOS-only app leaves out, can track training too. RollData also skips leaderboards and cross-user comparison entirely by design, keeping the focus on your own training history rather than competing with training partners.

The Verdict

Choose RollData if you want detailed tracking with features like position-technique mapping, round-by-round detail, training calendar. Choose Jits AI if you prioritize mobile app and voice logging. Both are solid options for BJJ practitioners, and the right choice depends on how you prefer to track your training.
