Best BJJ Apps in 2026: Training, Journals and Feedback

Choose a BJJ app based on what you need to improve. mmaGPT reviews your own training footage. Upload a clip of your rolls, drilling or positional sparring and it marks the flawed technique with video timestamps, then gives you a drill to train the habit out, in about 30 to 45 seconds. It runs in your phone's browser on iPhone and Android with no download, and your first session is free with no card needed. For a training journal, BJJ Notes; for free instruction, the Grapplearts BJJ Master App.

For feedback on your own footage, see the BJJ training app and AI BJJ coach. Your first review is free, no card needed.

BJJ has more high-quality content than any other martial art and almost none of it is calibrated to your specific game. The 2026 BJJ app landscape is split between deep technique libraries (great for what to learn), mat-time trackers (great for accountability), and feedback tools (great for what to fix). Here is the honest breakdown.

Pick a BJJ app for your next training problem

Your current problem	Tool to look for	What to check before paying
You need to learn a position	A structured instructional library	Teaching depth, gi or no-gi focus, and a clear sequence of lessons
A familiar move fails in your rolls	Feedback on your own footage	Corrections linked to visible moments, useful drills and limits stated clearly
You forget what happened in class	A journal or session tracker	Fast logging, searchable notes and export options
You want more consistent mat time	Attendance and training logs	A logging routine you can maintain after every class

If the problem is your own execution, the mmaGPT BJJ training app reviews drilling and rolling footage. If the problem is learning a new system, start with instruction from your coach or a library. You can use both.

Evaluate a video-feedback app with one position

Film a short positional round with your partner's permission. Keep both athletes in frame and choose a position your coach has already taught. Upload the clip, replay the reported timestamps and check whether the notes match what is visible.

Pick one correction to discuss with your coach. Drill it under supervision, then film the same position again. A useful review gives you a correction you can test. A confident description of action hidden behind another athlete is a reason to question the report.

Video cannot reliably show every grip, pressure change or injury risk. Share the original footage with your coach alongside the notes. Use the BJJ video analysis guide to plan a clear recording.

Which of these are free?

• BJJ Fanatics: no free tier, instructionals are purchased individually.
• Submeta: no free tier, monthly or annual subscription only.
• BJJ Notes, Train BJJ, BJJ App: core session logging is free, with in-app purchases for advanced features on the mobile apps.
• Beltchecker: completely free.
• Fight AI: free to download, but a subscription is required to use the coaching features.

BJJ apps by type

BJJ apps fall into four groups. Descriptions come from each app's own site and App Store ratings were checked on October 13, 2026; check each site for current pricing.

Best BJJ app for video feedback: mmaGPT

Video feedback

• mmaGPT: reviews your roll or drilling clip and gives you one fix plus drills. Web app, first session free.

Journaling and conditioning with AI features

• Grappling AI: voice logging and coaching; verify current features on its site.
• JuggernautBJJ: strength and conditioning programming for grapplers, rated 4.9 from 500 App Store ratings, though not updated since January 2025. It is a different training job from reviewing a roll.
• Bulletproof for BJJ: strength and mobility work for grapplers, rated 4.3 from 34 App Store ratings.

Training journals and trackers

• BJJ Notes: a journal for logging classes and techniques, with free core logging.
• Kimura: a BJJ training tracker. See their site.
• FlowRoll: a BJJ training log, rated 4.9 from 650 App Store ratings.
• Mattime: a mat time tracker for grapplers. See their site.

Instructionals

• BJJ Fanatics app: the app for watching BJJ Fanatics instructionals you have bought, rated 4.9 from 4,522 App Store ratings.
• Grapple Ninja: a grappling learning app. See their site.

Timers and drilling

• BJJ Drill Buddy: a drilling and round timer app for grapplers. See their site.

Which one at your belt

• White belt: a library. You need volume of technique before feedback has anything to correct.
• Blue belt: a library plus feedback. You know moves; this is where they start failing against resisting partners.
• Purple belt: feedback first. Your gaps are specific, and a library cannot tell you which of your details is the leak.
• Brown and black belt: feedback on the two or three positions you actually compete from, plus a library for opponent-specific study.

What separates a real BJJ app from a video dump

1. Does it know your level? A purple belt needs different content than a white belt.
2. Does it grade your roll, or just show you ideal rolls?
3. Does it understand gi vs no-gi mechanics?
4. Does it help you remember what you learned? A technique you drilled once and never logged or reviewed again is a technique you will forget by your next class.

The roundup

Best for: Grapplers who want frame-by-frame analysis on their drilling or rolling. What it does: Upload a clip, get back structural feedback on posture, frames, grips, transitions, plus a drill ladder. Strengths: Built by a two-time world champion martial artist, Collin J. Smith. BJJ-specific calibration. Runs in your phone browser on iPhone and Android, plus desktop, no download, add-to-home-screen supported. Intro pack: one free session, no card.

2. BJJ Fanatics, best technique library

Best for: Practitioners who want the deepest instructional library from world-class black belts. What it does: Massive on-demand library, organized by instructor, position, and system, with individually priced titles; see BJJ Fanatics for current prices. Strengths: Depth and quality are unmatched, and you own each title you buy. Weak spots: Pure library. Shows you the platonic ideal. Cannot tell you what your hips are doing wrong. Constant discount cycles make it hard to know what a "normal" price even is.

3. Submeta, best structured curriculum

Best for: Practitioners who want a guided progression rather than a content firehose. What it does: Curated curriculum-based learning with progression checkpoints, with subscription options; check Submeta for current terms. Strengths: Structure and intentionality, and the leg lock and no-gi competition content is particularly deep. Weak spots: Still no feedback on your actual rolls. Check the current subscription scope before paying.

4. BJJ Notes, best for a written training journal

Best for: Grapplers who want to write down what they drilled and rolled after every class. What it does: A training journal for logging techniques, rolls and mat time, at bjjnotes.app. Price: See their site. Platforms: iOS and Android. Weak spots: It records what you trained, not whether you trained it correctly.

5. BJJBuddy, best for submission stats

Best for: Grapplers who want numbers on how their rolling is actually going. What it does: A tracker for your rolling, submissions and taps, with charts. On the App Store. Price: See their site. Platforms: See their site. Weak spots: Stats only, no feedback on your technique.

6. Grappling AI, best for voice logging

Best for: Grapplers who would rather talk than type after training. What it does: A voice-powered training journal with an AI coach, at grapplingaiapp.com. Price: See their site. Platforms: See their site. Weak spots: Journaling and chat, not a review of your footage.

7. Grapplearts BJJ apps, best for free structured instruction

Best for: Free structured instruction. What it does: The BJJ Master App and BJJ Roadmap from Stephan Kesting, at grapplearts.com/mobile-apps. Grapplearts says the BJJ Master App includes 457 minutes of free instruction. Price: See their site. Platforms: See their site. Weak spots: Instruction only, so it cannot tell you what your version of a move is doing wrong.

8. Other trackers (Train BJJ, BJJ App, Beltchecker)

Best for: Logging mat time, tracking stripes, or looking up belt rank. What they do: Train BJJ logs rolls, techniques and streaks, bjj-app.net is a web tracker with a technique wiki, and Beltchecker is a community-run database for belt promotion history. Price: See their site. Platforms: See their site. Weak spots: Not coaching tools. They tell you how much you trained, not whether you trained correctly.

9. Grapplers Guide, the lifetime-access library

Best for: Practitioners who want a one-time payment instead of a subscription or per-title purchase. What it does: Lifetime access to a library of courses from a range of guest instructors for a flat one-time fee, check current access and pricing on Grapplers Guide. Strengths: No recurring cost once you have paid. Weak spots: Check that its courses cover the positions and ruleset you train.

10. Fight AI, the cross-training option

Best for: Grapplers who also train MMA disciplines and want one app across boxing, kickboxing, wrestling, BJJ and MMA. What it does: AI video upload and analysis, plus training plans, with a BJJ track alongside the other disciplines. Strengths: Free to download with a broad discipline spread on both the App Store and Google Play. 1 3 Weak spots: Core AI coaching features require a subscription, and BJJ is one of five disciplines rather than the primary focus.

Best BJJ journal and tracker apps

• For a training log you can watch: mmaGPT. Upload a roll and it keeps the clip with timestamped notes on what went wrong and a drill to fix it, so your log shows what to fix, not just what you did. Your first review is free.
• For a written journal: BJJ Notes, where you type up techniques, rolls and mat time after class.
• For submission stats: BJJBuddy, which charts your rolling, submissions and taps.
• For voice logging: Grappling AI, where you speak the session instead of typing it.

Most grapplers pair one of these journals with mmaGPT: the journal records what you did, mmaGPT shows you what to fix.

How to combine a library with a feedback tool

The two categories solve different problems and neither one replaces the other. A library like BJJ Fanatics or Submeta shows you a black belt's version of a technique, executed against a compliant or lightly resisting partner, filmed under ideal conditions. That is exactly what you need when you do not yet know a system exists. It is not what you need when you already know the system and it keeps failing against your actual training partners.

A feedback tool like mmaGPT works on your footage, from your gym, against your training partners, at your current skill level. It cannot teach you a technique you have never seen. What it can do is tell you which specific detail in your version of a technique you already know is the one costing you the position.

A workable routine for most grapplers: pick one position or sequence you are actively working, watch two or three versions of it in a library to build a mental model, drill it in class, then film your live rolling and run it through a feedback tool to see whether what you are actually doing under pressure matches what you watched. Repeat on the next position. Logging the session in a tracker afterward is what keeps the whole loop honest over months instead of weeks.

What to look for in a BJJ app in 2026

1. Content freshness. BJJ evolves fast, especially in leg locks and modern guard passing. A library with content from 2018 is not wrong, but it is incomplete against 2026 competition trends.
2. Ownership vs access. Per-title purchases (BJJ Fanatics, Grapplers Guide) mean you keep what you buy. Subscriptions (Submeta) mean you lose access if you stop paying, but you get continuous new content.
3. Gi vs no-gi specificity. Grip mechanics differ enough between gi and no-gi that a generic technique library or feedback tool that does not distinguish them is giving you half the picture.
4. Whether it actually watches your video. Several apps in this category market "AI analysis" that, on closer inspection, is closer to a generic move counter than a technique grader. Judge any AI feedback tool by whether the specific correction it gives matches what a coach watching the same clip would say.

How to pick

Most serious BJJ practitioners end up with two apps: a library (BJJ Fanatics or Submeta) for what to learn, plus a feedback tool (mmaGPT) for what to fix in your actual game. The library tells you the move. The feedback tool tells you why your version of it keeps failing. A tracker like BJJ Notes, Train BJJ, or bjj-app.net rounds things out by keeping a record of what you actually did.

If you only have time for one, pick based on the bottleneck:

• You do not know enough techniques yet → library
• You know techniques but they keep falling apart in rolling → feedback
• You just need to remember what you drilled → tracker

The second category is where most blue and purple belts plateau. It is also where the feedback tool earns its place. If you can name the exact position that keeps costing you, say, how to escape side control for BJJ beginners, or how to stop getting your guard passed, that is the drill your next film review should target. When there is no partner available, solo BJJ drills you can run at home fill the reps between classes.
