The Best BJJ Journal Apps of 2026, Checked Honestly

We make TOMO, so read this knowing that. A roundup is only worth reading if it is honest, so every price, rating and feature below comes from the app's own App Store listing, Google Play listing or website, read on September 27, 2026. None of it comes from other listicles. Where TOMO falls short, we say so, and we say plainly what we think of apps that sell themselves as a coach.

Ratings are US App Store figures, rechecked on September 28, 2026. Prices change often, so check the listing before you buy.

At a glance

BJJ Notes

iPhone and Android · free, Pro $7.90 a month, $59.90 a year or $149 lifetime · 4.7 from 175 ratings · updated September 26, 2026

The most complete form-based journal we found. You log rolls, drills, submissions, sweeps, takedowns, guard passes and taps, and tag each session as class or open mat, gi or no-gi, with the instructor and gym. It turns all of that into streaks, mat time, and subs and taps per roll, with a recap every week. There are no ads, and the free version holds up on its own.

Good fit if you like filling in fields and want numbers. Less good if you are too tired to tap through a form after class; the listing mentions no voice logging. App Store listing

FlowRoll

iPhone and Android · free up to 20 techniques, Pro $9.99 a month, $49.99 a year or $79.99 lifetime · 4.9 from 606 ratings · updated September 25, 2026

The most-rated BJJ journal on the US App Store, and the most social. You get a personal technique library and analytics, with a BJJ social network on top: followers, comments, leaderboards, gym groups and weekly challenges. It works offline and exports your data.

Good fit if you like training with an audience. Less good if you want your journal private. The free version also stops at 20 techniques. App Store listing

TOMO

iPhone only · three months free, then $5.99 a month or $49.99 a year · released September 2026, no ratings yet

Ours. You talk for about 90 seconds after class and TOMO writes up the session: techniques, rounds, submissions, injuries and notes. You can fix anything before you save. Once a week it writes a debrief that cites the sessions you logged and names what keeps happening, like "caught in armbars three weeks running." You can ask it follow-up questions, and it picks from 650+ checked technique videos to match the gaps in your logs. It saves with no signal, nobody else sees your journal, and recordings are deleted once they are transcribed.

It will not tell you whether your technique is right, because it has never seen you roll. The debrief turns a vague week into a specific question, and that question goes to your coach.

Good fit if you are wiped out after class and want the journal to read itself back to you. Less good if you are on Android, want a free tier or a lifetime price, want a social feed, or will not talk into your phone. It is also brand new, with no ratings yet.

Jits AI

iPhone and Android · pricing unclear, see below · 4.5 from 105 ratings · updated September 9, 2026

The closest app to TOMO. You log by voice on the way home (the listing says 30 seconds, the website says 20) or tap a quick check-in, and what the app calls an "AI coach" writes a debrief of the session. We have a view on that label further down. It also sets one focus a week, and adds per-partner scoreboards, a place to save clips from TikTok, Instagram and YouTube, and lessons from IBJJF No-Gi World Champion Henrique Rezende. Those lessons come from a person who has won at the top of the sport, and they are the part we would look at first.

Good fit if you want voice logging on Android, or like the scoreboard idea. Check first: the website lists a $1 seven-day trial, then $39 a year. The App Store lists plans up to $14.99 a month and $99.99 a year. See what the app offers you before you subscribe. App Store listing · website

BJJBuddy

iPhone and Android · free, Pro $5.99 a month or $39.99 a year · 4.4 from 462 ratings · updated September 22, 2026

The veteran, on the App Store since 2016. It charts your submissions and taps, recommends videos based on your stats, shows where your game has holes, and sends workouts to Apple Health. It added voice entry in May 2026.

Good fit if you want an app with a long track record and a cheap annual plan. Less good if you are on Android and care about reviews; it rates 3.6 on Google Play. App Store listing

Marune

iPhone and Android · free with ads, Peak $8.99 a month or $49.99 a year · 4.6 from 96 ratings · updated September 15, 2026

A training log for any martial art, including jiu-jitsu, judo, wrestling and Muay Thai. It keeps your belt history across disciplines and adds a competition tracker, a technique wiki, a social feed, and Apple Health and Apple Watch sync.

Good fit if you cross-train and want one log for all of it. Less good if you only do jiu-jitsu and want depth there. App Store listing

Grappling AI

iPhone only · $3.99 a month or $39.99 a year · no ratings yet · last updated April 8, 2026

The cheapest voice-first journal we found. You talk about your rolls and it pulls out the positions and techniques, then adds a stats dashboard, maps of how your rolls flowed, and matched YouTube picks. Don't confuse it with "Grappling AI: Mat Coach," a separate app from a different developer.

Good fit if price comes first. Less good if you want an app that is clearly being worked on. When we checked, it had gone almost six months without an update. App Store listing

The free option: a notebook or your notes app

Most people who journal their training use paper or Apple Notes, and that is a perfectly good choice. Both are free and flexible. They keep what you write and leave the organizing and pattern-spotting to you. If you go this route, use our free BJJ journal template and read it back once a week.

Others we checked

These are real and active but have only a handful of ratings so far:

• Kimura saves clips and maps how your techniques connect. $9.99 a month or $69.99 a year.
• MatTime is one quick log per class. $4.99 a month, $39.99 a year, or $39.99 once for life.
• RollForge takes voice logs and has an "AI coach" you can ask questions. Three ratings, last updated March 2026.
• Post Black Belt is a journal with an Apple Watch app and Apple Health.

Generic workout logs are built for sets and reps and have nothing for positions or submissions.

What about AI coach apps?

Search the App Store for "BJJ coach" and you will find plenty of software. On September 28, 2026, we counted at least seven BJJ apps with both "AI" and "Coach" in their names, Jits AI among them, and new ones keep arriving.

We don't think any of them is a coach, TOMO included. No app has trained jiu-jitsu. It has never felt a crossface, and it cannot see that your knee flares out every time you pass. A coach can, because a coach has spent years on the mat and is watching you. The black belts at your gym know things about your game that no transcript of your rounds will ever hold, and we doubt software ever gets there.

What an app can do well is keep an honest record and read it back to you. Knowing you got armbarred from mount in four of your last six classes is a better place to start than "I feel stuck." TOMO is built to do that job and then hand the question to a person: your coach, or a higher belt who will watch a round and tell you what they see. When an app calls itself your coach, treat it as marketing, and take your technique questions to people who earned the belt.

How to choose

• You will not pay anything: a notebook, Apple Notes, or the free versions of BJJ Notes or FlowRoll.
• You want numbers: BJJ Notes.
• You want a community: FlowRoll.
• You are too tired to type after class: a voice journal. TOMO if you want a weekly read of your own sessions in a private journal, Jits AI if you are on Android.
• You train more than one martial art: Marune.
• You want someone to fix your technique: your coach. No app on this list does that, ours included.

Whatever you pick, the app matters less than writing something after most classes, reading it back, and asking your coach about what you find.
