About
Jim Scott is a serial founder, full-stack developer, and long-time Brazilian Jiu-Jitsu practitioner based in Dublin, Ohio. He's a husband of 23 years and father of six. He spent years chasing performance across grappling, powerlifting, and strength training, and years frustrated by mobility apps that treated him like a beginner who needed 400 exercises to pick from.
ROMRx is the app he wanted: one that measures what your body actually can and can't do, tells you the three things to work on, and gets out of the way. Then it stacks, because his body doesn't stop being a body when he switches sports.
The Manifesto
1. Overwhelm is the enemy of adherence. Every mobility app on the market solves the wrong problem. They give you 400 exercises when the problem is that you don't know which three to do today.
2. Your body doesn't care what sport you play. The same 12 joints govern a BJJ guard retention, a heavy squat, a triangle kick, and a downward dog. Building seven different assessment engines for seven different sports is a waste. One engine. Many protocols.
3. Techniques should have a readiness score. "How does my range of motion compare to what this position needs?" is the question every athlete asks. Our answer isn't "here's a general warmup." It's Green, Yellow, or Red for that specific position, that specific lift, that specific pose, based on your ROM this week.
4. Data compounds. Advice doesn't. Every user makes the protocol better for every other user. That's not a feature. That's the whole thing.
5. Priorities change every six weeks. If your app is telling you to fix the same joint for six months, it's broken. The 6-Week Reassessment Cycle™ isn't a nice-to-have. Readiness colors compare your range of motion to what a position needs. They are not medical clearance and do not say whether a move is safe for you.
6. Free assessment. Fair dashboard. ROMRx Base, including the ROM assessment, is free through December 31, 2026. Then $60/year starting January 1, 2027, renews yearly until you cancel. Card required. Cancel online anytime. Canceling ends your access right away. Sport packs stack on top. No dark patterns, no bait-and-switch, no forever promises we can't keep.
