Let's cut to the chase — you've got training to get to. Your instructor, sensei, or that legend from the admin team has added you to DojoHub. That means you now have one place for everything that isn't actually training — which, let's be honest, is the annoying part. BOOK YOUR CLASSES See the schedule, pick your session, done. No more sliding into the group chat asking what time sparring is on. TRACK YOUR ATTENDANCE Turns out showing up is most of it. Now you can prove it. MANAGE YOUR MEMBERSHIP Payments, membership status — handled. Your instructor will thank you. Probably won't say it out loud, but they will. YOUR PROGRESS Belt grades, milestones, your journey — all tracked. Whether you're a fresh white belt or a battered veteran of the tatame, it's all here. Works for every martial art — BJJ, Karate, MMA, Muay Thai, Kickboxing, Krav Maga and more. If your school uses DojoHub, this is your app. You'll need an invite from your school to get started. If you're not sure, ask at the front desk. Or the big intimidating person near the bag rack. They're usually friendly off the mats.
