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.

BCS4Tennis,
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!
(~_~A),
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!
roscoecoltrain,
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!

forguinha,
Easy set up and it works!!!
Once you get your tripod, setting up the phone and linking with your opponent was pretty easy and painless. Line call feature worked well and helped with settling a few questionable calls!!
WFTT,
Like my own little umpire
Super simple way to keep my singles games fun — no more disagreements about whether it was in or out. I use this for matches plus swing vision for training. iPhone on the court is so useful!!
utscrap,
Great for Line calls!
This app is definitely really accurate for speed and line calls! Works great when I’m playing a friendly game with my friends!
DariaWalczak,
Good
Easy to navigate, set up well explained. Fun to try it while playing with friends 🎾
EmBenPete,
Love it! Easy to use
Great app, and so far flawless.
LGBDJT,
**8 Month Update** Absolutely worth it for a number of use cases, or just fun
I got it to double check my calls. I figure I won’t ever have a problem finding a match if I overrule myself haha! It’s turned into a lot of fun for all involved. We use it for practicing serves and speed tracking mostly. It’s extremely accurate. I had a problem at first where calibration would fail a few times then finally work. It turns out some pickle ball lines got in the way. There is a public update coming out to correct that. The founder/CEO sent me a direct email when that happened and he showed a ton of class in how he approached the issue. I’m a fan. And I’ll enthusiastically recommend to anyone that hits a tennis ball regularly.

This is an app that consistently adds more versatility and features. It was a bargain before. Now it’s a steal. Make sure you are connected to a decent data connection or WiFi. Some bits of analysis seems to be performed on their servers. That’s a good thing to me… it allows them to adjust their algorithms as often as they please for continuous improvement. Don’t worry, it’s not streaming video or pictures. It doesn’t even make it on my first few pages of apps that use cell data.
Just get a tripod and buy the subscription. You will end up paying a fraction of a penny per accurate judgment on unsure calls. We use it so many times every match and everyone trusts it.
