Description
- Interactive on-court tennis serve speed radar mode
- Challenge line calls without Apple Watch
- Rewatch challenge videos and keeps scores from your tennis matches
Turning your iPhone into an AI line umpire device for everyone to make their own Hawk-Eye like challenge. The tennis app to challenge line calls with reliable results. High frame rate, super simple, quick to setup.
The app also includes a free serve radar mode that is a ton of fun to use with friends, students or your own to measure your tennis serve speed without the need for radar or tracking gun.
Adopt the easy routine every amateur tennis player is striving for and play a fair tennis game:
1. Start the tennis app.
2. (optional) Sync up with your opponent by scanning QR code.
3. Setup your phone on a tripod facing your side of the court.
4. When there is a questionable line call, you have 10 seconds to trigger a line challenge by raising your right arm up for 3 seconds (beta), or using your Apple Watch. Your phone will show a steady flash for IN, a blinking flash for OUT, and the result will be audible. If you use an Apple Watch, you can see the results and picture there, too.
The Tennis Line Call App is the end of disagreements, cheating or self doubt about line calls when playing a tennis match.
You can also use the serve speed and In or Out analytics results to improve your game.
Works best with iPhone 11 and above.

Ratings and Reviews
Awesome app that’s been needed for a long time!
I have a few friends I play with who consistently make what I think are bad calls unintentionally. I probably do the same to them. Using this app has helped us all play with line call confidence. It’s seriously changed the dynamic of our games and takes away the doubt that sometimes arises with shots near or on the lines. It’s like having “Hawk-Eye” for ourselves. Cool app!
Works for us
Been looking for a simple, accurate app that my family can use. This has settled so many disagreements. It’s like having a referee with you. Been recommending this to our friends as well. Thank you for making this app!
Won’t detect ball, Great Customer Service
Had two phones on tripods, followed all directions on placement, no sun… The app loaded the game, paired with another phone and calibrated just fine. But every time we went to challenge, it says “NO BOUNCE DETECTED”. So like… it just didn’t work.
But, I emailed the company on the website. At like 9pm. They responded immediately at a late hour! And they’re trying to help. So definitely willing to give them the benefit of the doubt and hope to get this working!
