Pick one goal: a submission, a takedown, an escape. Go for it every time you roll. After class, tell Koala if it worked. That’s the whole app.
Koala is free, and always will be. No account, no tracking.

A free app for Brazilian jiu-jitsu (BJJ), gi or no-gi. You pick one goal, like a submission, a sweep, a takedown or an escape. You go for it every time you roll. After class you answer one question: did you pull it off? Koala then tells you where each goal stands: first time, getting better, getting harder, or you’ve got it.
A different kind of one. No long entries and no technique lists: one goal, and one answer after class, with a few words of note if you want. Koala keeps every day, so you can look back at how a goal went.
Yes, and it always will be. No ads, no subscription, no in-app purchases, no account.
Nothing it sends anywhere. Koala has no server and no analytics. Everything stays on your phone, with a copy in your own iCloud on iPhone if you want one. The App Store and Google Play privacy labels say no data is collected.
No, that’s your coach’s job. Koala keeps track of what you’re working on. To start somewhere, «Ideas» has no-gi systems for each belt, without videos or explanations.
Reminders before and after class, widgets, your month in a calendar, systems that chain goals from a position, a round timer for open mat, your sleep from Apple Health or Health Connect, a countdown to a competition with an optional weight goal, and images to share a goal.
iPhone and Android, in English, Spanish and Portuguese.
