Description

“Tennis Serve Tracker” measures tennis serve speed using video processing and image recognition technologies. Why is it worth trying it when there are similar apps on market? Because all these apps can be split on 2 categories - first are the ones that do it very, very bad or simply invent measured speed and won’t be mentioned here at all. The others do measure the serve speed, but it’s a lot of manual interactions with setting multiple parameters, like choosing deuce/ad serve type, server height, marking server and ball positions on the standard court image template that has no resemblance to the actual court we see with our eyes. These actions drastically increase an error margin, time and effort required to perform a single serve speed measurement - does it match fast pacing tennis game we all love?
So how “Tennis Serve Tracker” measures tennis serve speed? The fundamental difference is that it processes every single frame in the video feed and recognizes the court on the image frame. It allows to reconstruct 3D world coordinates of the server and ball from the image coordinates. Application provides constant feedback by highlighting court lines, net and a ball on the screen. Now having the time measurements from the video and ball world coordinates application can calculate your serve speed with a great accuracy, most times way better than a commercial speed gun (see doppler effect cosine factor error)! Visit “Demo Videos” application website page for videos with real time side by side comparison between speed radar gun and the app.
Final speed display is unlocked by lifetime "Premium" upgrade just for a price of a single tennis balls can. This app is a valuable tool for every tennis player who would like to improve their game and have a great serve!

Tennis Serve Tracker Reviews

I spent money purchasing the pro edition, regrets

This app is not good by any stretch of the imagination. It does not integrate with anything, takes very short clips, which renders it impossible for me to set up shot, hit record and then serve. The algorithm doesn’t even properly triangular tennis court lines if there is the slightest hint of judder from Tripod. I would like my money back... that or remove from store because it’s really a waste of money and fairly undeveloped.

Doesn’t track anything

Constantly fails to recognize the serve and then doesn’t allow you to set the ball bounce point to have it calculate from there. No slow motion. Virtually useless

Hmmm

Convoluted. Can’t get it going

Terrible

The app closes everytime it says to “touch screen”. Lol hurt much developer.. your app is flawed and not working.. I have the most recent update on iPhonex and my Android both of which do not like your app.. please start over with rewriting your code.. we, (buddies at school, all tech majors) see the flaw in your app.. but was worth buying another one, which displayed accuracy. Pipe dream of free app exploded 😞

Liked it!

Tried several other apps before, but only this one was easy and quick to use on a court to measure my speed,

Great app!

Very unique idea with court recognition from the video and nicely done. Visual feedback during recognition feels like a game!

Tennis Serve speed

Amazing app for tennis fans. Easy and convenient to use. More accurate and reliable then speed gun. Developer is very responsive to any questions or recommendations. My son is open level tennis player and we use this app almost daily.
