Free vs Paid BJJ Apps: What's Worth Paying For
By RollData Team
We build RollData, a free BJJ training log with a paid tier, so take the following with that in mind. We're not neutral. But the honest answer here also happens to be the one that costs us money to give, which is as close to a guarantee of good faith as you're going to get from a company blog post: most people should start on a free plan, and a lot of grapplers never need to leave it.
That's not a hedge. It's the actual conclusion, and it's worth explaining why before getting into which specific paid features are worth your money.
The habit is the product, not the feature set
A training log only works if you open it after class. That's the whole mechanism: notice patterns over months, not weeks, and the way you notice them is by having logged sessions consistently enough that a pattern has something to sit on. No feature list changes that. A $10-a-month app with beautiful charts and zero entries teaches you nothing that a blank notebook doesn't.
This matters because it's tempting to treat a subscription as a commitment device: pay for the app, and you'll use it. That logic doesn't hold up. Motivation bought at checkout evaporates by the second missed week, same as a gym membership. If you haven't logged consistently for a month on a free tier, paying for a nicer version of the same habit you're not doing yet won't fix the gap. Build the habit first, on whatever costs nothing, and let the decision to pay come later, driven by something specific you've bumped into rather than something you hope will motivate you.
What paid tiers typically gate
Once logging is a habit, most apps in this space put roughly the same handful of things behind a paywall. Here's each one, assessed honestly.
Advanced analytics
Charts of technique frequency, position win rates, training load over time. This is the single most defensible thing to charge for. It's genuinely more expensive to build than a log screen, and it's the feature that turns months of entries into something you couldn't have seen by scrolling back through them yourself. Worth paying for once you have enough logged history that a trend line tells you something a memory doesn't, usually a few months in. Not worth paying for on day one, when you have four entries and nothing to analyze yet.
Unlimited techniques
Several free tiers cap you at a fixed number of custom techniques, commonly 20. FlowRoll and Kimura both do this. Whether the cap matters depends entirely on what you're logging: if you're recording sessions with a handful of core moves you drill often, 20 might last you a year. If you're the type who logs every variation and every position by name, you'll hit the wall in a few weeks and either pay or start reusing entries that don't quite fit. This one is worth paying for specifically once you've hit the ceiling and feel it, not preemptively.
Media and video attachments
Photos of whiteboard notes, video clips of a roll or a drill. Nice when you have it, rarely the reason anyone upgrades. Most people already have their coach's technique videos on their phone's camera roll or saved from Instagram; duplicating that inside a training log adds storage overhead without adding much you couldn't get by just remembering which folder it's in. Worth it mainly for people who film every class and want everything in one place. Skip it otherwise.
AI insights
The trendiest gate, and the one to be most skeptical of. Jits AI leans on this entirely, with essentially no lasting free tier: a one-dollar seven-day trial, then $39 a year direct (more through the App Store). Generic pattern-spotting on a small, personal dataset is a hard problem, and BJJ is contextual in ways a model can't see: your coach knows your frame is collapsing because they watched you roll, not because you logged "lost position" three times. AI summaries of your own log entries can be a pleasant convenience. They're rarely worth paying a premium for on their own, and if a whole app's pricing rests on this feature, that's worth noticing.
Ad removal
Marune's free tier carries ads, with a separate $3.99-a-year purchase just to remove them, on top of the $8.99/mo or $49.99/yr Peak tier for actual features. Paying a few dollars a year purely to stop seeing ads in an app you open daily is a reasonable, low-stakes purchase for some people. It's not a feature in the sense the others are: you're not getting new capability, you're buying quiet. Fine to do if it bothers you, easy to ignore if it doesn't.
Competition tracking
Match records, opponent notes, results by tournament. Only relevant if you actually compete, in which case it's genuinely useful: your competition history is a different kind of data than your training log, and having it structured is worth something once you're stepping on a mat under lights a few times a year. If you don't compete, this feature is invisible to you either way, paid or not.
The cap that actually matters
There's an important difference between the FlowRoll/Kimura style of cap, which limits how much you can log, and a cap that only limits what you can do with data you've already logged. A 20-technique ceiling on core logging is a cap on the habit itself: it stops the thing that makes a training log valuable in the first place, right around the point most people are just getting started. A cap on analytics or exports, by contrast, limits what you can see, not what you can build. You still have the data. You're just not getting the nicer view of it yet.
Kimura reportedly paywalls around 90% of its content, which is worth knowing going in rather than discovering after you've logged a month of sessions and hit a wall on all sides. A free tier that caps logging itself is a much bigger deal than a free tier that caps analysis, because the first kind can quietly kill the habit before it forms, and the second kind never does.
This is also the design decision behind RollData's own free tier: no caps on sessions, techniques, partners, or history. The paid tier ($4.99/mo or $49.99/yr) adds advanced analytics, competition logging, and training goals, the "nicer view" category rather than the "can you log at all" category. Data export is free regardless of plan, which matters for a different reason: your training history shouldn't be hostage to whichever app you picked two years ago.
How to decide
Before paying for any BJJ app, ask yourself four questions:
- Have I logged consistently for at least a month already? If not, nothing you pay for will fix that. Wait.
- Is the thing I'd be paying for a cap on logging, or a cap on analysis? A logging cap is worth solving immediately if you've hit it. An analysis cap can wait until you have enough history for analysis to say anything.
- Would I miss this feature specifically, or does it just sound good? "Advanced analytics" sounds good to everyone. Whether you'd actually open that screen monthly is a different question, and only your own usage answers it.
- Am I comparing against the free tier I'm actually on, or against a hypothetical better one? A lot of apps in this space differ meaningfully on what's free versus paywalled. If you're frustrated with a cap, check whether a competitor's free tier just doesn't have it before assuming you have to pay to solve it. Comparisons across the major apps are worth five minutes, including the honest case for a spreadsheet if you'd genuinely rather own the raw data than use any app at all.
The bottom line
Paid tiers earn their price when they add analysis on top of a habit you've already built: charts, exports, competition history, the stuff that turns logged sessions into insight. They earn it much less when they gate the logging itself, or when they're selling motivation you're supposed to already have. Start free, log for a month, and let a specific frustration, not a feature list, tell you when it's time to look at pricing.
