About
What is BallSpeed?
BallSpeed is a free web app that measures ball speed from a slow-motion phone video, entirely on your device. Your video never leaves your phone; it shows your football shot, tennis serve or volleyball spike speed in km/h or mph, awards badges, and lets friends compete on leaderboards. Not a radar gun — a fair, relative measurement for everyone.
Honest accuracy
BallSpeed is not a radar gun. Everyone is measured with the same algorithm, so rankings are fair. We explain the methodology in detail:
