As a purple belt who competes regularly and also coaches kids’ BJJ, I find Grapplerules an incredibly useful resource.Having all the information for different competitions in one place, including rules, legal submissions, weigh-in requirements and restrictions for different ages and belt levels, makes preparing for competitions so much easier.From a coaching perspective, it’s equally valuable. Being able to quickly check the rules for specific age groups and competitions allows me to tailor my coaching and ensure the kids are properly prepared for whatever competition they’re entering.The dedicated parents section is another great addition, helping parents understand what to expect when their kids compete.A brilliant app for competitors, coaches and parents alike. Takes a lot of the hassle out of navigating different competition rulebooks. Highly recommend!

BJJ rules can be complicated whether you’re a new beginner trying to understand it all, or a seasoned competitor trying to work out what ruleset the comp you’re doing allows. And the section for parents is awesome. It makes it really easy to see what’s allowed for the many different age groups, belts and competitions. Great app.

Really helpful having it all in the same place instead of having to trawl the internet for obscure pages.
