The Best BJJ Training Apps in 2026

By RollData Team

This roundup is written by the team behind RollData, which is one of the apps in it. That is a conflict of interest, and you should read everything below knowing it.

Here is how we tried to handle it. Every price, platform and rating below was checked against the live App Store, Google Play listing or the app's own pricing page in September 2026, not copied from somebody else's roundup. Where we could not verify a claim we left it out. And we have named the readers for whom a competitor is the better buy than our own app, because there are several, and a roundup that never reaches that conclusion is an advert with a table in it.

How we judged these

We looked at five things: how much friction there is in logging a session, what the free tier gives you before it stops being useful, which platforms it runs on, how deep the data goes, and whether the pricing is straightforward. We only covered apps for logging your own training, so instructional and video-library apps are out of scope.

BJJ Notes

Platforms: iOS and Android. No web version. Price: free tier, then PRO at $7.90 a month, $59.90 a year, or $149 once for lifetime access.

BJJ Notes is the most complete single app on this list. It logs rolls, drills, submissions, sweeps, takedowns, guard passes and taps, plus competition results, injuries and recovery, and a "technique in focus" system for picking something to work on and tracking it. At 4.7 out of 5 from 175 App Store ratings it has the best combination of score and sample size here, which is more meaningful than a perfect score from a handful of users. The free tier is genuinely usable rather than a trial: unlimited logs, injury tracking and technique goals are all there without paying.

The weakness is price. $59.90 a year is the most expensive subscription in this roundup by a distance, and $149 for lifetime is a real commitment for a training log. There is also no web version, so reviewing a year of notes means doing it on a phone. The specific trade-offs against ours are on the BJJ Notes comparison page.

If you want one app that holds everything and you will genuinely use the injury and competition tracking, BJJ Notes is a better buy than RollData, and we would tell a friend that.

MatTime

Platforms: iOS only. MatTime's own site says Android is planned after the iOS app is further refined. Price: free to download, with Pro at $4.99 a month, $4.99 a week, or $39.99 once for lifetime. MatTime's pricing page lists no free plan.

MatTime's pitch is "Strava for BJJ" and it delivers on that more literally than anyone else here: weekly and monthly leaderboards, streaks, gym leaderboards, a public profile showing your hours, belt and gym, and the 10,000-hour framing that makes accumulated mat time feel like it is going somewhere.

The weakness is that the App Store rating base is effectively empty at the time of writing, so you are buying on the pitch rather than on other people's experience. It is also iOS only. The early-access $9.99 lifetime price has ended, so $39.99 is the real number now. Our side-by-side is on the MatTime comparison page.

If external competition is what gets you to the gym, MatTime beats RollData outright. We have no leaderboards and no plans to add any, so if that is your motivation, we are the wrong tool.

FlowRoll

Platforms: iOS and Android. Price: free tier capped at 20 custom techniques. Pro is $9.99 a month, $49.99 a year (often discounted to $34.99 a year), or $79.99 for lifetime.

FlowRoll is offline-first in the real sense, not the "syncs eventually" sense: in a basement gym with no signal it works the same as anywhere else. It pairs that with voice logging and an AI coach, so the walk from the mat to the car is enough time to record a session. It also has a social layer with leaderboards, and its ratings are strong.

The weakness is a surprising gap: no belt or promotion tracking and no training calendar. Neither appears in its App Store feature list or on its official site. For a lot of grapplers, belt progress is the single thing they want a log for.

If you train somewhere with no reception, FlowRoll is the right answer and RollData is not. We are a web app with no offline support, and no amount of feature depth fixes a page that will not load.

Marune

Platforms: iOS and Android. Price: free with ads. Peak is $8.99 a month or $49.99 a year, and removing ads alone is a separate $3.99 a year purchase. 4.6 out of 5 from 96 iOS ratings.

Marune is a social app that happens to log training. There is a feed, gym check-ins, a schools directory, gi wear tracking so you can see which gi you are actually rotating, and belt tracking that covers multiple martial arts rather than assuming BJJ is the only thing you do.

The weakness follows from the same thing: logging depth is shallow next to the dedicated loggers. You record that you trained and who with, not what happened in round four. Two separate purchases (Peak, and a cheaper ad-free tier) is also an awkward way to price an app.

If you train more than one martial art, Marune handles that and RollData does not. We track one art properly rather than several loosely, which is the right call for us and the wrong one for you if you also hold a judo or muay thai rank.

Kimura

Platforms: iOS only. Price: free tier capped at 20 techniques. $9.99 a month or $69.99 a year. 4.5 out of 5 from a small number of ratings.

Kimura is a technique notebook rather than a session log, and the best one here for that. Its visual map links moves to each other, so a sweep connects to the pass it sets up and the submission at the end of it, and you can embed video on individual techniques. If you think about jiu-jitsu as a tree of connected positions, nothing else here represents that as well.

The weakness is the paywall. Roughly 90% of the content sits behind it, and that is the dominant complaint in its reviews. The free tier is a demo, not a plan.

If you want video attached to your notes, pick Kimura or FlowRoll over RollData. We do not support video or media attachments at all, and that is a deliberate decision rather than a backlog item, so waiting for us to add it is a bad plan.

Grappling AI

Platforms: iOS. Price: $3.99 a month or $39.99 a year.

Grappling AI is the cheapest subscription here. You record a voice note after training and it transcribes it, pulls out the positions, submissions and sweeps you mentioned, and files them into a stats dashboard and a searchable journal. It also ships a library of over a thousand annotated professional matches.

It has too few App Store ratings to display an average, so there is no independent read on how well the extraction works, and extraction quality is the entire product: if it consistently mishears a technique name, your data is quietly wrong in a way you will not notice for months. We could not verify an Android version, so treat it as iOS only. More detail on the Grappling AI comparison page.

Jits AI

Platforms: iOS. Price: $1 for a seven-day trial, then $39 a year direct from jitsai.com. Through the App Store the same app is $14.99 a month or $99.99 a year. There is no lasting free tier.

Jits AI is built around voice-first logging with AI debriefs, a weekly technique to focus on, and heavy gamification: XP, streaks, missions and leaderboards. If you train more when a streak is on the line, that is a real feature and not a gimmick.

The weakness is the pricing split. $39 a year on the website versus $99.99 a year in the App Store is a large gap for the same product, and it is easy to tap the wrong one.

BJJBuddy

Platforms: iOS and Android. Price: $5.99 a month or $39.99 a year. 4.4 out of 5 from 462 App Store ratings, the largest review base of any app here.

BJJBuddy has been around longer than most of this list and it shows in the review count. It tracks submissions, sweeps, takedowns and taps, charts them over time to show where your game has holes, and sends sessions to Apple HealthKit so rolling sits alongside your other training.

The weakness is that its analytics are built almost entirely around submissions and taps, a narrow slice of what happens in a round: you learn who tapped whom, not which position you kept losing. And HealthKit, arguably its best feature, is not something Android users get. See the BJJBuddy comparison page for the full breakdown.

If your training data should live in Apple Health, BJJBuddy does that and RollData does not.

RollData

Platforms: responsive web app. No native app, no app store listing, no offline support. Price: free tier with no caps on core logging. Pro is $4.99 a month or $49.99 a year for advanced analytics, competition logging and training goals.

We log at round level rather than session level, which is the main thing separating us from most of this list. A session is not one event: it is six rounds against five people, each with its own positions and outcome. Those rounds hang off a position-to-technique taxonomy and partner tracking, so "I keep getting passed from half guard, specifically by taller people" is a query rather than a hunch, and the free tier does not cap any of it. See what is included or the plan breakdown.

The weaknesses are real. No offline support, so a gym with no signal is a problem. No video attachments and no social features, both on purpose and neither coming. And no native app.

Which one should you pick

  • You train where there is no phone signal. FlowRoll. Nothing else here is properly offline.
  • You want video attached to your technique notes. Kimura first, FlowRoll second.
  • Leaderboards and streaks are what get you to class. MatTime on iPhone, Marune if you want a feed too.
  • You train more than one martial art. Marune.
  • You will never type a training note. Grappling AI at $3.99 a month, or Jits AI if gamification helps, at the website price.
  • You want your rolls in Apple Health. BJJBuddy.
  • You want one polished app for sessions, competitions and injuries, and the price is secondary. BJJ Notes.
  • You are on Android, or you switch between phone and laptop, or you want round-level detail without paying. RollData.
  • You would rather own the raw file than use any app. A spreadsheet, honestly. We wrote the case for that as well, and it is a better fit for more people than app companies like to admit.

These apps differ less than their marketing suggests. The one that works is the one you still open in March, so pick on platform and friction first and treat the rest as a tiebreaker.
