Built by players. Powered by AI.

TennisFlow was created by a small team of passionate tennis players and AI experts with one clear mission: to help players of all levels analyze and improve their game through smart, accessible technology.

Like many ambitious players, we often asked ourselves the same questions after training:

Was my technique correct? Why does my forehand feel inconsistent? What exactly am I doing differently from better players?

Getting precise answers usually requires expensive coaching, special equipment, or countless hours of trial and error.

We believed there had to be a better way.

That's why we built TennisFlow — an AI-powered tennis coach that analyzes your strokes, compares them to professional movements, and gives you instant, personalized feedback using nothing more than your phone.

What started as a personal passion project quickly became something much bigger.

Today, we are continuously improving TennisFlow with one goal in mind: helping players of all levels learn faster, train smarter, and enjoy the game even more.

We're still at the beginning of this journey — and that's what makes it exciting.

Every training session, every piece of feedback, and every player using TennisFlow helps us make the app better.

Because great tennis is built on constant improvement — and so is TennisFlow.

What Players Say About TennisFlow

"I always thought my forehand was better than my backhand. When I saw the analysis, I realized my backhand actually looked much more fluid due to shoulder rotation. It took some practice, but now my forehand is not only faster and more precise, it also looks really good."

- Markus F., Club Player

"As a coach, I use TennisFlow for my students. The analyses show my students very precisely where movement patterns can be improved. As a result, they understand technical corrections much faster than through my explanation alone."

- David Tivanovac, Tennis Coach

"The app is super intuitive and easy to use. The analyses help me focus on my weak points. I always have my phone with me anyway, so I use the app in every session. My whole family shares the PRO subscription now. Thank you to the developers."

- Julia M., Club Player

"As a beginner with only a few coaching sessions, a few weeks ago I could hardly find tennis partners willing to play with me. So I borrowed the ball machine at my club and practiced basic strokes. TennisFlow recorded and analyzed every session from the side. The feedback felt overwhelming at first. Over time, though, I felt TennisFlow was getting to "know" me and responding personally. My technique has improved noticeably and visibly."

- Petra M., Club Player

"I recently completed my tennis coaching qualification and wondered how to use modern video analysis effectively without spending a fortune on equipment. When I first tried TennisFlow, I immediately saw its potential. My favorite features are the slow motion and the pro comparison."

- Karsten Budig, Tennis Coach
