TENS: Tennis Tracker

TENS turns your iPhone into an on-device tennis tracking and analysis companion. Point your camera at the court and TENS uses computer vision to detect the court, follow player movement, recognize strokes and track the ball. Record a live session or import an existing tennis video, then review detailed performance insights without creating an account. FEATURES • Automatic tennis-court detection • Live player, stroke and ball tracking • Shot counts and forehand/backhand breakdowns • Court heatmaps and movement analysis • Speed, distance and session summaries • Match video recording with analysis overlays • On-device analysis of imported videos • Apple Watch workouts with heart rate and active energy • Live Activity session statistics PRIVATE BY DESIGN TENS performs its analysis on your devices. It has no advertising SDK, third-party analytics or account system, and the developer does not collect your personal data. Camera positioning, lighting and device performance can affect tracking accuracy. TENS is intended as a training and analysis tool, not a substitute for professional coaching or officiating.
