OffCourtz

OffCourtz is a mobile tennis coaching brand that uses real-time, explainable AI to help players improve their technique. Available worldwide on iOS and Android, its app lets users record or upload videos of their shots and receive frame-by-frame analysis, scores across more than 20 technical parameters, and personalized recommendations. Supported shots include serves, forehands, one- and two-handed backhands, volleys, and overhead smashes, with more types planned.

Rather than overwhelm players with statistics, OffCourtz highlights key focus points and matches weaknesses with drills from a library of more than 900 animated exercises. Players can practice, record the same shot again, and track their scores and progress over time. The service is designed for different experience levels, from beginners to advanced players, and requires no specialized equipment beyond a phone and racquet. OffCourtz offers a free trial with three analyses and a paid subscription that includes unlimited video analyses, exercise access, progress tracking, and priority support. Video processing is described as secure, with users’ videos not shared with third parties.
