Question 1

What is CoachEx?

Accepted Answer

CoachEx is a tennis coaching app that records your swings and analyzes them to provide personalized coaching feedback live, in your ear while you practice, or later when you are reviewing the recordings.

CoachEx analyzes the mechanics of your swing and generates coaching feedback tailored to what you are actually doing. Unlike general instruction such as YouTube videos or articles, the feedback is based on your own swings.

CoachEx also allows you to have a conversation with your coach. You can discuss the feedback  while you are on the court practicing, or later when you are relaxing at home. You can ask follow-up questions, request additional tips, ask for a different explanation, or ask to see the technique demonstrated in video form. The system can generate custom instructional videos that combine your swings with professional demonstrations.

Question 2

How is CoachEx different from other tennis coaching apps?

Accepted Answer

It's the Coaching.Many tennis apps focus on video recording, generic tips, or complicated stroke analysis and statistics. While these tools can be useful, they leave you, the player, to interpret the results on your own and decide what to change. They leave you to coach yourself. CoachEx is designed to provide an interactive, personalized coaching experience that is laser-focused on helping you improve your technique.CoachEx's unique capabilities include:Live coaching tips, while you practice, like a private lesson with a dedicated human coachRecord swings from matches, rallies and practices.

Question 3

How do I use CoachEx during practice?

Accepted Answer

Using CoachEx is designed to be perfectly natural - just like talking with a personal coach.Set your phone off to your side so it can see you - ideally with a tripod but that is not required. Put in your earbuds so you can hear your coach and ask questions. Start practicing. This can be on court with a partner, a ball machine, or during solo serve practice.As you swing, CoachEx provides verbal coaching guidance through your earbuds based on the mechanics of your motion, and you can ask your Coach questions. You can then adjust and continue practicing.Improvement in tennis comes from repetition with feedback:Swing → feedback → adjust → swing againCoachEx helps you repeat that loop faster.CoachEx automatically identifies and saves individual swing clips, making it easy to review each swing later with Coach's feedback.

Question 4

What if I don't practice by myself?

Question 7

Can AI really coach tennis?

Accepted Answer

We think so, and so do our many satisfied customers.CoachEx is not a full replacement for the judgment of experienced human coaches. A talented human coach giving you a private lesson is hard to beat. But let's be real. Human coaches offering private lessons: are expensivecan be hard to schedule usually don't come watch you play matchesusually make you come to themGroup lessons are less expensive, but have the same limitations. And as anyone knows who's taken a lesson with 4, 8, or more students: you rarely get any personalized feedback. At larger class sizes group lessons are mostly just exercise.CoachEx focuses on something technology can do very well: analyzing body motion and comparing it to effective technique. CoachEx uses AI to deliver coaching that fits your schedule, budget, and location preferences.By combining high speed motion analysis with AI-generated coaching guidance, CoachEx can identify areas where your swing mechanics differ from proven technique and work with you to help you understand what to adjust. Unlike older tennis apps that tried to wow you with stats and gee-whiz visuals, CoachEx is focused on you, and helping you get the advice you need to improve.

Question 8

Will CoachEx work for my swing?

Accepted Answer

Yes. CoachEx analyzes your individual swings, which means the feedback is based on what you are actually doing rather than a generic model of how a swing should look, or what only the top pros can do.Players often find that simply being able to review their swings clearly using video playback is helpful. Then on top of that CoachEx gives them guidance tailored to their motion so they can understand how to adjust their technique much more quickly.

Question 9

Is CoachEx useful for beginners?

Accepted Answer

Yes! Beginners can use CoachEx to learn proper technique and build good habits early. Because the feedback is based on your own swings, it helps you understand what you are doing and how to improve.

Question 11

How accurate is the swing analysis?

Accepted Answer

CoachEx analyzes the mechanics of your swing using motion analysis and computer vision technology. The system looks at key elements of the stroke such as body movement, timing, positioning, and sequencing to identify areas for improvement. Evaluations are based on synthesized performance of a multitude of other players.Like any coaching tool, it works best as part of regular practice and experimentation. Many players find it especially valuable because the feedback is based on their actual swings, not general advice.

Question 12

How does CoachEx track my improvement over time?

Question 14

Can I use CoachEx if I don't have access to a tennis court?

Accepted Answer

Yes! As long as you can swing a racket, you can get coaching.

While most customers use CoachEx on a court with tennis balls, our customers are quite creative, and these use cases are fully supported:
Working with a backboard, garage door, or wall
Shadow swings (no ball) in a living room or hotel room
Toss drills (partial or no swing) anywhere you like

Question 15

Can I practice at home?

Accepted Answer

Yes! CoachEx can analyze both real swings and shadow swings. This means you can work on your technique even when you don't have access to a court, or where it wouldn't be practical to hit a ball, such as your living room or a hotel room.

Question 16

Can I get coaching after a match or practice?

Accepted Answer

Yes. CoachEx saves your swings as individual video clips, making it easy to review your session afterward.

If you recorded your match or practice, you can get coaching later just by asking your coach for feedback while reviewing your swing recordings.

If you got Live Coaching in a lesson, you can review that coaching guidance at your leisure, and compare your recorded swings with professional demonstrations to better understand what to adjust in your next practice.

Question 17

How is CoachEx better than watching tennis videos online?

Accepted Answer

Typical online instruction provides general advice that may or may not apply to your swing. It's great to watch the pros do their thing, but the rest of us are nowhere near that level.

CoachEx analyzes your swing and provides guidance tailored to what you are actually doing, and what you can absorb at your skill level.

Question 18

How is CoachEx different from sending a video to a human coach for review?

Accepted Answer

Video review services can be helpful, but they tend to be costly, and the feedback typically arrives long after the practice session is over, so it is too late for you to adjust in the moment. CoachEx provides guidance while you practice, so you can immediately apply what you learn.

Question 19

Does CoachEx replace a tennis coach?

Accepted Answer

CoachEx can be valuable whether or not you work with a human coach. Many players use it to reinforce between lessons what they are practicing with their human coach, while others use it as a convenient way to receive personalized guidance during their own practice sessions.

Question 21

What can I do for free?

Accepted Answer

it's hard to get this right
there's a lot of video to review later

At the free tier:
CoachEx watches while you play or practice, isolates the swings, crops the video to feature only you, and produces a short clip of just that swing
CoachEx organizes all these swing recordings by swing type, location, and time
Swing clips can easily be shared with others

Accepted Answer

Yes, although functionality will be limited. Without a network connection you can:

Coaching guidance itself requires a network connection. If you record swings while offline, you can receive coaching later once you reconnect.

Question 23

Is CoachEx difficult to set up?

Accepted Answer

No! Most players simply place their phone to the side of the court so the camera can see their full body and swing. A tripod or phone stand can help keep the camera stable, but is not required. In a pinch, you can prop the phone up against a water bottle or bag.

Aim your phone so it can see you as you move around. Lansdscape orientation is best. Your coach will guide you on where to stand if you're having trouble.

Once recording starts, CoachEx automatically detects and saves individual swing clips and organizes them so you can review them easily. Coach will tell you if you move out of view.

Question 24

What equipment do I need?

Accepted Answer

For recording swings with optional coaching later, you need:
your phone (iPhone 11 or later)
a tennis racket
a tripod (optional) - a tripod is better but not necessary
tennis balls (optional) - you can do shadow swings anywhere and still get coaching

For live coaching, you need earbuds (to listen to and chat with your coach as you practice)

Question 25

How should I position my phone to record swings?

Accepted Answer

For best results:
Position your phone to your side where it can see you best, perpendicular to the direction of ball travel.
if you are right-handed, position your phone to your right side so your Coach can get the best view of your swing
if hitting backhand strokes, position to your left side
if you are left-handed, reverse the positions above
Place the phone far enough away to capture your full body and the entire swing. A minimum distance of about 10–15 feet (3–5 meters) is recommended.
Rotate the phone to landscape orientation so the coach can track your movement as you move across the court.
Using the front camera can make it easier to check framing and review feedback when you walk up to the phone.
For the most consistent results, use a tripod and position the camera about 3 feet (1 meter) off the ground.
