Trazo: Golf Ball Tracer

Turn any golf swing video into a broadcast-style ball flight trace — with automatic on-device ball tracking, a full manual mode, and six arc styles you can color, glow and tune in seconds.

TRACE YOUR SHOT IN SECONDS

Pick a swing from your camera roll or record one right in the app. Tap the ball at impact, tap it once in flight, and Trazo follows the real ball frame by frame — drawing the arc it actually flew.

WHY TRY IT

Real Ball Tracking – Trazo detects the actual ball in your footage and fits a perspective-correct flight path. Draws, fades and towering apexes look like they really happened, because they did.
AI Ball Detection – A trained on-device model finds the ball at address and rescues it mid-flight when it's only a few pixels against the sky.
Manual Mode – Prefer to draw it yourself? Flip one switch and shape the arc by hand. Impact stays locked to the ball; drag the curve, apex and landing until it's exactly right.
Six Arc Styles – Solid, Fade In, Fade Out, Bubbles, Needle and White Hot. Every style tapers into the distance for a true sense of depth.
Any Color, Any Glow – Ten color presets plus a glow slider from subtle to blazing.
Built-In Stabilization – Shaky handheld footage is smoothed before tracing, so the arc stays locked to the ground instead of swimming.
Fully On-Device – Detection, tracing and rendering all run on your iPhone. Your videos never leave it.

MADE FOR SHARING

Export at full quality with your arc rendered straight into the video. No watermark on Premium. Post your best drive the same minute you hit it.

PRIVACY-FIRST

Your videos stay on your iPhone. Trazo does not upload your footage, and we do not sell your data. Ball detection and tracing run entirely on-device.

IMPORTANT NOTE

Trazo is a video effect tool for entertainment and social sharing. It draws the visual path of your shot — it does not measure carry distance, ball speed, spin or launch angle, and it is not a launch monitor or a substitute for one. Tracing accuracy depends on lighting, background, camera angle and how clearly the ball is visible; Manual Mode is always there when automatic tracking doesn't nail it.
