--- Pro-level serve tracking - no radar needed! ---
With the Tennis Serve Speed Tracker, your iPhone or iPad measures serve speed, 3D flight path, angle, net clearance, and session stats so you can track your serves like a pro - whether for fun, serious training, or coaching - and no radar is needed.


--- How It Works ---
... it’s super simple!

(1) Set up (30–60 seconds):
Mount your iPhone or iPad on a tripod (or alternative mounting option like a strong clamp). Place it near the net, facing the service box you’re targeting. Follow the easy and quick in-app calibration.

(2) Serve naturally:
Go to the baseline, toss the ball, and hit your serve as usual. When the ball contacts the racket and bounces in the service box, the app’s sensors capture both sound and video.

(3) Smart analysis on your phone:
Using advanced algorithms, the app automatically reconstructs the ball’s 3D flight path, measures net clearance, calculates the serve angle, and (with Premium) computes the ball speed. All processing happens directly on your iPhone or iPad - no internet or extra sensors needed.

(4) Instant feedback:
Results appear immediately on your screen. Want to keep practicing without walking back to the device? The AI voice will read out your serve speed and outcome after each serve. Pair it with Bluetooth headphones for private, on-court coaching!

(5) Track your stats:
After multiple serves, view your session stats: maximum and average speeds and angles, consistency, and serve placement on a court map.


--- Free vs. Premium ---
Start with the Free Version to make sure the app works on your device and court, and get a taste of what’s possible.
If you are happy with the accuracy of the tracking in the Free Version, consider upgrading to Premium - for less than the price of a can of tennis balls - and unlock the full pro experience:
• Serve Speed: Just like the numbers you see at Grand Slam tournaments.
• Automatic Mode: Train continuously with instant voice feedback after every serve. Perfect for solo sessions.
• Serve Statistics: Get instant stats for your current session.


--- Features ---
Free Version:
• 3D Serve Reconstruction: Visualize your serve trajectory on a 3D court.
• Serve Angle: See how much you can drag your opponent off-court.
• Net Clearance: Measure how safely your ball clears the net.
• Manual Mode: Track one serve at a time.
• Built-in Tutorials: Step-by-step voice and video instructions guide you through setup, calibration, and practice.

Premium Version:
• Serve Speed: See the serve velocity (km/h or mph). The app's algorithms take into account effects like air resistance and gravity, and are calibrated against a real radar gun.
• Automatic Mode: Track multiple serves in a row hands-free, with instant AI voice feedback. Perfect for solo practice.
• Serve Statistics: Check averages, max values, consistency, and placement on a court map. Spot patterns. Train smarter. Practice like the pros.


--- Requirements ---
• Stable Device Mounting: Use a tripod, clamp, or other solid mount. Hand-held setups are not supported. Your iPhone or iPad must remain completely still during calibration and recording.
• Quiet Environment: The app relies on audio cues (racket hit, ball bounce). Avoid nearby courts with ongoing ball exchanges, wind, sudden noises, and strong echoes.
• Lighting & Shadows: Moderate, even lighting works best. Avoid rapid changes in light or strong shadows across the court.
• Session Focus: Focus each tracking session on one serve type (e.g., flat, slice, or kick) for meaningful stats.


--- Who is it for? ---
• Casual players: Compete with friends and have fun.
• Ambitious players: Train with the app and improve.
• Coaches & clubs: Give players instant feedback without expensive equipment or include serve tracking in your next club event.

Happy serving!

You want to know how fast your Tennis serve is, but you don't want to buy an expensive radar system?
Maybe you want to practice serves and see basic statistics?

The Tennis Serve Speed Tracker app is for you! Turn your iPhone or iPad into a handy serve tracker for practicing or competing with your friends!


How it works:

(1) Mount your iPhone or iPad on a tripod and place the tripod next to the net, facing the service box. Follow the simple in-app calibration instructions (takes less than 1 minute). After calibration, the app will record the sound of your serves and will film the ball flying into the service box.

(2) Go to the baseline and get ready to serve. Once you hear a sound signal from the app, get ready, toss the ball, and serve.

(3) After each serve, the audio and video data is analyzed fully automatically on your device. The app indicates the speed of your serve and whether it was in or out. Results are shown on the display and read out by an AI voice if you like (bluetooth headphones are supported). This way, you can keep serving without running back and forth to your device.

(4) Once you have completed several serves, you can see basic statistics on how you have performed.

The app is optimized for tracking serves if you are alone or with a friend/trainer. If you are alone, you can simply listen to the AI voice for feedback while serving. If you are with a buddy/trainer, one person can serve while the other inspects the results.


Two Versions - Free vs. Premium:
The Tennis Serve Speed Tracker can only compute good results when a couple of requirements (see below) are met. Use the Free Version to test if the app works in your environment (i.e., on your court). If your serves are tracked well in the Free Version, consider upgrading to the Premium Version to unlock all the Premium features (see below).


Main Features:

(1) Serve Accuracy:
See on a court map where your serve has landed and whether it was out, in, or even inside the target zone close to the service line.

(2) Serve Angle:
See the angle of your serve - how far can you drive your opponent out of the court?

(3) Serve Speed (Premium Version only):
See the average and maximum ball velocity in km/h or mph. The maximum velocity is the value measured and displayed in big Tennis tournaments. The app even takes into account the effects of air resistance and gravity to compute the speed. For this, the app's algorithms use a physics-based simulation model and were calibrated against a real radar gun.

(4) Serve Statistics (Premium Version only):
See basic statistics about the last couple of serves you have completed, such as the maximum or average serve speed achieved, or the percentage of serves that went in. Also, you can inspect the spatial distribution of the serves on a court map.

(5) Manual Mode:
In the Manual Mode you can manually track and analyze one serve at a time.
This mode is optimized for two persons: one serves, the other one operates the app and inspects the results to provide feedback to the server.

(6) Automatic Mode (Premium Version only):
In the Automatic Mode you can fully automatically track multiple serves in a row and receive feedback after each serve from an AI voice. Once all serves are completed, you can inspect them and see basic statistics.
This mode is perfect for practicing serves on your own and optimized for single users. Tip: Use bluetooth headphones to practice serves without anyone but you hearing the results!


General Requirements:
(!) Ensure that your device is completely static (i.e., not moving) when calibrating and recording serves. Use a tripod and don't hold the device in your hand.
(!!) Ensure the environment is quiet so that the microphone can hear the serve and the ball bouncing off the court.
(!!!) Ensure the court is brightly illuminated so that the camera can see the fast ball.
