B.A.A. Racing App vs Span

The B.A.A. Racing App is your home for Boston Marathon & B.A.A. race tracking, leaderboards, information, course maps, and more!

Span turns a video of your climbing into something you can actually read. Point it at the wall, or import a climb you have already filmed. Span finds your body in every frame and draws it back as a moving skeleton — where your weight sits, where your hands and feet have been, how straight your arms are through the crux. WHAT YOU SEE • A live skeleton over the camera, and burned into what you record • The path your centre of mass took through the whole climb, drawn on the climb itself • Arms-straight percentage, left-right balance, how direct your line was • A stick-figure animation driven by your own movement MEASURED, NOT GUESSED Tell Span your height and wingspan once and it gains a ruler. From then on it reads heights in metres instead of body lengths, and works out your arm, leg and torso lengths from your own climbing. The estimates sharpen as you record more. EVERYTHING STAYS ON YOUR PHONE There is no account, no server and no upload. Pose detection runs on the device. Your climbs, your measurements and your video never leave it unless you share a file yourself. Span is a feedback tool for technique. It is not a medical or diagnostic device, and its measurements are estimates from a single camera.
