FAQ
COMMON QUESTIONS
What camera/phone do I need?+
Any modern smartphone works. 240fps slow-motion is the sweet spot — most recent phones support it. More is always better. 120fps works but gives less detail on fast wrist mechanics. Film from the side and slightly behind for the best angle.
How fast will I get my analysis back?+
Within 7 days. Umut will always give advance notice if he's travelling or on vacation.
What counts as one session?+
One session = you submit 2-3 clips → Umut analyzes and sends back a full response (video breakdown + 2 slow-mo examples + written summary). You can also ask 1-2 follow-up questions after receiving your feedback to make sure you understand what to work on before the next session.
Can I ask follow-up questions?+
Yes — each session includes the option to ask 1-2 clarifying questions after your feedback. There's also an optional voice note clarification if something needs more explanation.
Is this for beginners or advanced players?+
All levels. Whether you're a beginner building your first cut serve, an intermediate player trying to add consistency, or a pro dialling in mechanics for competition — Umut meets you where you are and works from your current level. He's coached players across the full spectrum and adapts his feedback accordingly.
What if I'm not satisfied?+
Message Umut directly and it will be sorted out — you'll get your money back. He coached 100+ players for free. He's not here to take your money and disappear.

What athletes say
An important quality to serving is understanding how to break form down into different phases, and I feel like whenever you give me feedback, it's always in steps that I can understand and implement. Even through the course of the day I can see either more consistent jump, contact, grab on the ball or all the above.

Your input mainly helped me focus on the important things and basics again, because I tend to lose sight of them quickly when serving since you want to pay attention to a thousand things at once. It also always helps to have someone you can ask whether one technique or another is more effective :)

You can not imagine how much time I spent serving and trying the wrong way. Then Umut started to help me and I improved so quickly it was unbelievable. He did not try to change my technique completely, he gave me adapted tips, step by step to improve from my starting point. If you want to improve your serving game, I would recommend no one else 😊
