Company profile
researched Sep 2026SwingVision, operating as Mangolytics Inc., develops a mobile application that applies computer vision to video of tennis and pickleball play captured by a single camera. The app runs on iPhone, iPad, Mac and Apple Watch and tracks shot speed, depth, accuracy and rally length in real time, generating automated stats, scoreboards overlaid on video, shot-by-shot and point-by-point review, and trimmed highlight reels of rallies. Users can also record with other devices such as a GoPro or an Android phone and upload the footage for post-session analysis.
Additional features include automated scoring, electronic line calling with the ability to challenge calls via slow-motion replay on Apple Watch (Series 5 or newer), Siri-initiated practice and match sessions, workout export to Apple Activity and HealthKit, weekly goal setting and post-session coaching suggestions. A coach- and team-facing dashboard lets parents, coaches and teams track students' scores and statistics over time, with tools such as voice-over and annotation and integrations with other coaching software. The company describes its AI as patented and its team as including AI specialists formerly at Tesla and Apple.
Founding story
Co-founders Swupnil Sahai and Richard Hsu were roommates at UC Berkeley who played tennis together and observed that detailed performance data was available to professional players but not to everyday ones, while apps such as Strava were serving cyclists and runners. Around 2016, while working on his PhD, Sahai learned Swift and built an Apple Watch app to track tennis swings and shots and keep score manually. He subsequently worked on Tesla's Autopilot program, where experience with computer vision for tracking cars and pedestrians suggested the same approach could track tennis swings and shots; because iPhone hardware could process video in real time and was widely owned, the team built an iOS app, launching officially in 2019.
Business model
SwingVision distributes a free app with usage limits (the free tier provided two hours of recording and analysis per month) and sells a SwingVision Pro subscription that unlocks automated scoring, line calling and unlimited cloud storage. Subscriptions are billed through the Apple App Store on monthly or annual auto-renewing terms.
Consumer and coach subscriptions via in-app purchase. SwingVision Pro was listed at $179.99 per year or $14.99 per month in the US, with prices varying by country.
Traction
The iOS app holds a 4.7 average rating from about 4,900 ratings and an Apple Editors' Choice award. More than 2,200 Tennis Australia coach members received free Pro subscriptions through the Tennis Australia agreement. As of late 2021 the company had built the product with a team of fewer than 10 people and reported growth in downloads and usage through the COVID-19 pandemic.
Latest developments
The app has expanded from tennis to cover pickleball and is listed on the App Store as the official player and ball tracking app of Tennis Australia, the LTA and the ITA. Following its seed round, the company outlined plans to grow the team, build an Android app and expand its international subscriber base, with a roadmap including a fully automated umpire, live streaming of matches, real-time technique coaching and multi-camera court support.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
SwingVision positions itself as the only solution delivering real-time shot tracking, stats and line calling from a single camera, aiming for a leading share of a market it sizes at 87 million global tennis players. It holds official tracking-app designations with several tennis federations and collegiate tennis's ITA, and has received Apple Editors' Choice recognition.
The product requires only a single smartphone camera rather than dedicated court installations, combining shot tracking, automated scoring, line calling and highlight generation in real time at consumer subscription pricing, versus the professional-grade analysis systems that were previously available only to touring players.
Technology
On-device computer vision running on iPhone/iPad cameras identifies and tracks shots, ball landing locations and match play in real time from a single camera, without additional court hardware. Algorithms detect points and automatically trim footage into highlight segments, produce line calls and generate statistics; the Apple Watch app supports manual scoring, shot bookmarking and challenge replays. Video captured on other devices, including GoPro cameras and Android phones, can be uploaded for post-session processing. The company states its AI is patented.
Go-to-market
Distribution is primarily through the Apple App Store, supported by App Store editorial features and Apple keynote mentions, endorsements and investment from professional players, and partnerships with tennis governing bodies and equipment brands. SwingVision is described as the official player and ball tracking app of Tennis Australia, the LTA and the ITA, and works with the USTA. A Wilson partnership offered Wilson tennis customers a free 30-day trial and a $20 discount on a Pro subscription, promoted via QR codes on inserts in Wilson Championship ball cans.
Recreational and competitive tennis and pickleball players of all levels, as well as parents, coaches, teams, collegiate programs and national tennis federations.
Geography
Sold internationally through the App Store in nine languages, with federation relationships spanning the United States (USTA, ITA), Australia (Tennis Australia) and the United Kingdom (LTA); the company participated in the Techstars SportsTech accelerator in Melbourne.
History
After the 2019 launch, professional players James Blake and Andy Roddick invested in the company. In early 2020 SwingVision was accepted into the Techstars SportsTech Melbourne accelerator, whose corporate partners included Tennis Australia; the program led to an agreement giving more than 2,200 Tennis Australia coach members free SwingVision Pro subscriptions. The company joined Apple's App Store Small Business Program and was featured on the App Store and referenced in Apple keynotes between 2020 and 2021, including a September 2021 keynote announcing the A15 Bionic chip and Apple Watch Series 7. In June 2021 it raised a $2M seed round led by Tennis Australia's venture arm Wildcard Ventures.
Risks & controversies
User reviews report inaccuracies in automated scoring, such as points being awarded to the wrong player after an out call and difficulty correcting point outcomes in the editing interface. The product has been dependent on Apple platforms and App Store distribution, with Android support still a stated roadmap item.
