PurpleShift turns your phone into an AI testing lab. Measure your body, time your sprints and track your vertical, then prove it with verified results that coaches and scouts can find. DON'T JUST MEASURE. SCAN IT. Skip the tape measure. PurpleShift's AI Body Scan reads your height, wingspan and hand size from your phone's camera, and shows how confident the AI is in every reading. DON'T JUST TIME IT. BREAK IT DOWN. A stopwatch gives you one number. PurpleShift gives you the whole run, with no timing gates needed. Set your phone up at the side of the field and the AI does the rest. • Start mode measures acceleration from a standing start • Fly mode measures top-end speed from marker to marker • See your time, speed, splits, velocity curve and stride-by-stride breakdown DON'T JUST JUMP. FIX YOUR FORM. A jump test tells you how high you went. PurpleShift also tells you why. Record a standing or approach jump and get your jump height, air time and a form score, plus the extra inches better form could add. GET VERIFIED. GET RANKED. Verified results go on live PurpleShift leaderboards. Filter the rankings by test, camp or athlete and see where you stand: overall, in the 40-yard dash, the 10-yard dash, the 5-10-5 agility shuttle and more.
