Frame
A BJJ training journal built against the forgetting curve.

02 / FRAME
Frame is a BJJ training journal built on a hard truth: you forget most of what you’re taught within days. Log a session in seconds by voice, and Frame holds every technique, brings it back just before you’d forget it, and shows you — in plain data — that you’re actually improving. Built for the belts who feel stuck, so they have a reason to keep turning up.
Different belts, different excuses, one mechanism: when progress goes invisible between classes, people drift.
Belt-attrition figures are community estimates, not studies — we treat them as the shape of the problem, not proof of it. ~6M practitioners worldwide (Gymdesk); median UK adult membership £70/mo (Matador, 2026).
1For the individual
You forget most of what you are taught within days, and you cannot see yourself improving. Frame holds the detail and shows you the proof.
2For the room
The cheapest growth in jiu-jitsu is the member you already have, kept one more year. A room that can see its own progress is harder to leave.
Built against the forgetting curve
A single session throws four or five details at you — the grip, the angle, the small correction that made the sweep finally work — and within a week almost all of them are gone. Frame is built around that decay rather than despite it.
Everything you log comes back to you on a schedule: a few days later, then a week, then a month, timed to land just before you’d lose it. There’s nothing to revise and no flashcards to sit down with — the app works out what’s about to fade and puts it in front of you. Retention is the product, and it’s the one thing a notebook has never done.

The log you’ll actually keep
Everyone knows they should keep a training journal. Almost nobody does, because writing one up after an hour of getting choked is the last thing you want to do.
Frame removes the friction: talk for thirty seconds in the car — “started in closed guard, hit a scissor sweep to mount, got swept, tapped to an armbar” — and it transcribes on-device and turns it into a structured session you just confirm.
Then it reads your game back to you: the positions you live in, the subs you land, the ones that keep catching you, and hands you one or two specific things to hunt next session. A plan, not a feed.


The app wears your belt
Frame is built for the belt journey and it shows it — the whole app takes on the colour of your rank and changes with you as you’re promoted. It runs offline-first and keeps your training history yours: saved the instant you log it, private, exportable, never sold.
The goal underneath every decision is simple and hard: make the progress you can’t feel visible, so the belts who’d otherwise quit have a reason to come back for the next stripe — not more features, but more people still on the mat a year from now.

We scoped Frame typing-first, with voice as a nice-to-have. Every test said the same thing: if logging costs more than thirty seconds, nobody does it — and a journal nobody keeps is worthless. So voice became the product and typing the fallback. The exact opposite of how we’d planned it.
Scope. What is public here is the athlete's app — the first surface of a longer system, and the only part we will show until it has earned the next. The work behind it, and who it is being built with, stays off the site on purpose.
