Get a $5,000 analysis of your serve's Kinetic Chain FREE
Dr. Kovacs' Lab – Now on your phone
Even the pros have breaks in their Kinetic Chain, which is a fancy science term for how you generate power from your entire body and get it into the tennis ball.
In 2011, Dr. Mark Kovacs published the world's leading study of the serve's Kinetic Chain, it's called "An 8-Stage Model for Evaluating the Tennis Serve."
Before today, the only way to get an A-Z analysis of your serve's Kinetic Chain from Dr. Kovacs was to fly to Atlanta, GA, and spend two days in his lab. The analysis cost $5,000 not including airfare and hotel.
Now, with computer vision, which is a branch of artificial intelligence, we can do that same analysis with your phone…

What happens after the trial?
If you decide to stay after the 14-day free trial, it's just $29/mo to keep improving with Bert – upload new serves, track improvements to your Kinetic Chain, and remove all the guesswork about what you need to do next because Bert will just tell you (and provide new drills!).
10% Speed Guarantee
Your serve is backed by our 10% Speed Guarantee. After your 14-day free trial, you'll have an additional 30 days to work with Bert to increase your racket head speed by at least 10% (and yes, Bert can measure it). If you don't, we'll give you a full refund, because I don't want your money if you're not serving faster.
