About
DeepSwing is a professional-grade golf swing analysis app built for iPhone and Apple Watch. Powered entirely by on-device AI, it captures and evaluates your swing in real time—no internet connection or cloud upload required, making it a privacy-first solution for golfers of all skill levels. The app analyzes each swing frame by frame, automatically detecting phases such as setup, backswing, downswing, impact, and follow-through. It measures kinematic angles, spine alignment, swing plane, club path, and tempo, then benchmarks them against ideal ranges to surface what's actually causing misses—whether it's setup, sequencing, path, or face control. DeepSwing's live coach feature provides audio, haptic, and visual feedback between repetitions so you can make real-time adjustments during practice. Advanced AR overlays layer swing plane, hand path, and ball-flight tendencies directly over your recorded video, while a rotatable 3D skeleton playback lets you inspect posture and rotation frame by frame. AI Coach Tips translate the data into plain-language coaching cues in multiple languages, explaining what changed, why it matters, and which drill to work on next. Session history lets golfers compare progress over time to verify that mechanical changes are sticking. DeepSwing is ideal for amateur and competitive golfers seeking objective, data-driven feedback without the cost of an in-person instructor, as well as coaches who want a visual tool to support their students.
