Best App to Track Sparring: Timers, Journals or AI Video

You spar twice a week, maybe three times if work behaves. A month later you could not tell anyone what happened in those rounds. You remember the one tap you got and the one you gave up. Everything else is gone.

That is the problem a sparring tracker solves. The question is which kind. There are three real options: a timer, a journal, or AI video analysis. They are not interchangeable. One tells you how long you trained. One tells you what you think happened. One shows you what actually happened.

Here is how they stack up, with the apps worth knowing in each category.

Option 1: a round timer

The cheapest option. Most gyms already run one on the wall. A timer tracks volume: rounds done, minutes on the mat. That is useful for consistency, but it tells you nothing about quality. Six rounds where you got mounted six times and six rounds where you swept everyone look identical on a timer.

If volume is all you want to track, use any free interval timer and skip to the next section. A timer is a stopwatch, not a tracker.

Option 2: a training journal

A journal is the classic answer. After class you write down what you drilled, who you rolled with, what worked and what did not. Over months, patterns show up: you keep getting passed on the same side, you never finish the triangle choke you keep setting up.

A few apps are built for exactly this.

BJJ Notes is a BJJ training journal for Android and iPhone: notes, logging and recall, no video analysis. Its site says it is free to download and use, and the US App Store listing shows a PRO monthly purchase at US$4.99 (read 2026-10-21). Its site publishes its own store ratings of 4.9 out of 5 on Google Play and 4.8 on the App Store (read 2026-10-21).

Marune sits in the same category: a BJJ training log, not a video tool.

Grappling AI is the interesting one. It is a voice-powered BJJ journal for iPhone. After training you talk about your rolls, and the AI pulls out positions, techniques and key moments from what you said. It builds a stats dashboard with attacking versus defending and submission success rate, a visual map of your position transitions, and suggests YouTube instructionals matched to techniques you used. For people who hate typing after a hard session, talking into your phone in the car park is a much lower bar.

None of these are weaker versions of video analysis. They are a different tool. But every journal shares one hard limit: it records what you noticed. If you got swept because your base was wrong thirty seconds before the sweep, and you never noticed, your journal never finds out. Memory after six rounds is not a reliable witness.

Option 3: AI video analysis

This is the newest category and the one that changes the equation. Instead of writing what you think happened, you film the round and let software read the footage. You get back what actually happened, with timestamps.

DARCE

DARCE is our pick, and here are the specific reasons. It is a mobile AI coach built for four martial arts in one app: BJJ, wrestling, striking and MMA. You film one angle of your roll or sparring round on your phone, upload it, and it reads the whole round position by position. No sensors, no markers, no second camera. One fixed phone angle.

What comes back is a timeline mapped to the second, so you can jump straight to the moment you lost the position instead of scrubbing through footage. On top of that you get up to three fixes tied to their exact moment, plus one position to drill next. That last part matters for anyone training around a day job: you do not have time to work on ten things, you have time to work on one.

DARCE also ships a technique library of 90+ techniques across BJJ, wrestling and striking, each broken into step-by-step frames. When the breakdown says your knee slice pass stalled at the underhook, or your low kick is landing without hip rotation, the reference is already in the app. Join now if you want your rounds read this way.

The honest caveat: if you train a discipline outside BJJ, wrestling, striking and MMA, some of the apps below list more styles on paper.

Fight AI

Fight AI is an AI boxing and MMA coach for iPhone and Android, at fightai.app. Its site lists five disciplines: boxing, MMA, Muay Thai, wrestling and jiu-jitsu. You upload or record a clip, pick your martial art, add a question about what you are working on, and get AI observations and suggested drills. It also has an AI coach chat and personalised training guidance. Free to download, with a subscription required to access its features. Its site shows a 4.4 out of 5 rating from 100 App Store ratings.

JAB AI

JAB AI covers a lot of ground: AI-generated video workouts, real-time voice coaching during rounds, and video analysis of your own footage. You upload sparring or training footage and get an annotated breakdown video with feedback on stance, footwork, strike mechanics, and timing and reactions. Its site lists nine disciplines, and its US App Store listing (read 2026-10-21) says video analysis covers ten, with 111 lessons across 24 programs. It has 10k+ downloads on Google Play, and its US App Store listing showed 4.7 from 497 ratings on 2026-10-21. The apps are free to download, but Pro unlocks the AI video analysis; the US App Store listing shows auto-renewing purchases from US$4.99 a week to US$79.99 a year (read 2026-10-21). The listing also says you can film a round in the app of up to 90 seconds, or upload one.

mmaGPT

mmaGPT runs in the browser at mmagpt.app on phone, tablet and desktop, with no app to download. You upload a 20 to 60 second clip of drills, bag work, pads or sparring, and the report ranks what to fix first, shows the moment in your video where each mistake happens, and gives you a drill to fix it. It lists eleven disciplines. Its homepage says about a minute from upload to your first fix; its AI sparring analysis page says a review takes 30 to 45 seconds, watches the whole round, and asks for one round at a time filmed side-on at chest height. Your first analysis is free with no card and does not auto-renew into a plan. Paid plans run US$19 to US$49 a month depending on how many analyses you want, and a single analysis costs US$3.99 with no plan (read 2026-10-21 on mmagpt.app/pricing). Its site frames itself as a second set of eyes that supports your coach, which is the right way to think about every tool on this list. A native app is in development.

MMA AI: Cage Coach

Cage Coach, from Doved Studio, scores your clip from 0 to 100 with frame-by-frame notes on striking, takedowns, clinch work, transitions and ground positions, and adds an AI chat coach called Coach Rico. Beyond video it packs in multi-week programs, drills with spoken cues, round timers, food photo logging, weight and fight countdown tracking, and clubs with leaderboards. It is on iPhone, iPad and Android. Its site publishes no prices; the US App Store listing says the app requires a paid plan and lists purchases from US$7.99 a week up to US$119.99 lifetime (read 2026-10-21).

RollPlan

RollPlan is a BJJ match analysis web app, labelled beta and powered by Google Gemini. Anyone can sign up and use it now. Upload match footage and it returns positions, transitions and key moments, each linked to a timestamp, with coaching notes. You can pause the video and ask an AI chat about the exact frame. Its standout feature is competition prep: it imports AJP, IBJJF or Smoothcomp brackets or scans a tournament stream, then writes a gameplan with a win probability. The free tier gives 15 analyses a month and one active tournament with no credit card; Pro is 5 euros a month or 50 euros a year. A typical 5 minute match takes 2 to 4 minutes to analyse. Phone apps are coming but not out yet. If you compete in BJJ, this one is built for your exact problem.

Ground CTRL: BJJ

Ground CTRL is iPhone-only and BJJ-only. You film a roll or match, answer a few questions (outcome, starting position, gi or no-gi), and get a 7-section coaching breakdown with timestamps and drills: performance summary, positional analysis, submissions, transitions, defense, recommendations and questions to ask your coach. It also includes a white-to-black belt curriculum, progress tracking with belt progression, and strength and conditioning programming. Free to download; CTRL Pro gives 10 AI roll analyses a month for US$9.99 a month or US$79.99 a year.

A note on FightCamp

FightCamp comes up in these searches but it belongs in a different category: an at-home boxing and kickboxing workout system built around hardware, with a console and four trackers in every package, starting at $299. It is trainer-led workouts with AI motion technology for accountability, not a footage analysis tool, and not built for MMA or BJJ. Good at what it is for. Not a sparring tracker.

Comparison table

How to pick

Match the tool to the question you are asking.

"Am I training enough?" Use a timer or any journal. Volume is a counting problem.

"What do I think is happening in my rolls?" Use a journal. BJJ Notes if you like typing, Grappling AI if you would rather talk. Reviewing your own notes before class is a habit that pays off on its own.

"What is actually happening in my rounds?" Use video analysis. Memory lies, footage does not. If you only do BJJ and compete, RollPlan's bracket scouting is a genuine edge. If you only want short striking clips reviewed, mmaGPT's free first analysis costs you nothing to test.

If you train across disciplines, which most hobbyist MMA people do, DARCE is the one built for that: one app that reads your BJJ rounds, your wrestling exchanges and your striking spars the same way, from one phone angle, and hands you one position to drill before next session. You stop guessing whether your sprawl timing or your mount escape is the thing bleeding points, because the timeline shows you.

Whatever you choose, film a round this week. The worst tracker is the one you never start.
