Serve every day for 30 days
Upload a clip.
See what your serve is doing well, and what is holding it back.
Upload a clip of your serve and get a real read on three things that decide whether the serve is built to last: how you load your legs, how you reach through contact, and how you land. Honest scoring on what is working and what to fix first.
From behind, your full body in frame. 3–8 seconds covering one full serve.

A grade, three trait scores, and one thing to focus on.
Without an account, your clip is analyzed and then deleted. About 3–8 seconds covering one full serve works best. Grading takes about a minute — hang tight.
Every serve is measured against pro-calibrated criteria for three traits — judged by what the movement does, not by whose name it resembles. This is what a 3/3 looks like. Lefties are graded mirrored.
Deepest bend lands right at the trophy position, around 50–55% flexion — hips drop, heels lift, and the legs drive up in one continuous push. Loading energy, not posing.
At contact the body forms one taut line from racket fingertips to trailing toes — elbow locked, back foot off the ground, contact at the highest point of the whole motion.
The planted foot touches down at least a full foot-length inside the baseline, on the leg opposite the hitting hand — balanced, and driving forward into the court.
