The Tennis Line Call App is now available on the App Store for iOS devices.
Tennis players can use the new app to detect whether or not a tennis ball has gone out of bounds. The app works by each player strapping their smartphone to the top of a tripod, with each phone facing a different side of the court. The app then analyzes each side of the court and detects when a ball goes out of bounds. Players can trigger a challenge using their smartwatch. A flashing light for five seconds, paired with a verbal “out” indicates the ball bounced out.
“We’ve been working on this for three years now. This is our biggest milestone yet,” said Julien Duhautois, co-founder and CEO of Line Call. “I couldn’t be more proud of the team. It’s very exciting to finally launch and be able to generate traction and revenue, which will in turn fuel our efforts to achieve even bigger milestones.”
“There are four pillars that are foundational to our app. It has to be 1. Reliable 2. Simple 3. Affordable 4. Accessible. We’re doing amazing with the first three. To improve with the “Accessible” part we have two big achievements in sight,” said Duhautois. The first one is what we call the ‘hands up challenge’ meaning one can raise their hands up to trigger a line call review. It’s a patented solution we came up with and it will remove the need for our users to own an Apple Watch. The second one is to release a version of the app on Android. We are fundraising now so we can achieve these goals by early 2023.”
“We wouldn’t be there without the amazing Iowa startup ecosystem,” said Duhautois. “I compare it to a family. Gravitate has given us a home. Venture School, Iowa Startup Accelerator, and the Greater Des Moines Partnership have given us an education. IEDA has given us a financial buffer. And everyone else in our network has provided wisdom and guidance.”
