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. HOW IT WORKS Choose a swing video, or record a new one in the app. Trim to the moment of the shot. Confirm the ball at impact — Trazo usually finds it for you. Tap the ball once in flight, and optionally where it lands. Watch the trace build, then fine-tune with the Impact, Apex and Landing handles. Design the arc — style, color, glow — and save or share. WORKS WITH EVERY SHOT Drivers, irons, wedges, chips and bunker shots Down-the-line and face-on camera angles Standard speed and slow-motion footage 30fps, 60fps and 120fps recordings Portrait video, ready for Reels, Shorts and Stories 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. Download Trazo and make every shot look like it was broadcast. This app offers an optional subscription that unlocks Premium features (e.g. unlimited traces, watermark-free export and all arc styles).
