Kai Tennis has completely transformed how I practice. The setup was surprisingly quick and easy and within seconds it was connected to the ball machine. I was impressed with how intuitive the drills are. The app makes customizing trainings super accessible and it goes a long way showing you exactly what will happen in each training. I would recommend Kai to anyone looking to improve their tennis game regardless of skill level.
Wow! Made my ball machine sessions so much more effective!

This makes controlling the machine so easy, as I can do it remotely. I’m also able to do way more complex drills really tailored for what I need. I’m getting so much more out of my time with the ball machine and also want to use the ball machine more!
Game changer

Best tool that it’s available when a personal coach is not accessible. It has helped me tremendously with various drills on different types of shots. It’s the perfect tool and easy to use.
Must have
