Golf Ball Tracker- G-Tracker

G-Tracker is a golf shot tracer app that lets you record a golf swing video or import a video saved on your phone, then manually draw a ball flight path over it. Without complex equipment, you can add a smooth gradient shot trail to vertical swing videos recorded on your smartphone by adjusting the start point, apex, and landing point, then save the finished video. Key Features Record vertical golf swing videos up to 15 seconds Import swing videos saved on your phone Manually adjust the start point, apex, and landing point on the video Set the start timing of the ball flight trail Add a smooth gradient trail with a natural tail effect Generate MP4 videos based on 720x1280 / 24fps Save and share the result video locally on your device G-Tracker is designed with an offline-first approach. Video processing and saving are performed on your device without uploading videos to a server. You can use the app without logging in, and watching an ad may be required before generating the final video. It is ideal for golfers who want to make the ball launch direction and flight path easier to see in driving range, golf course, or indoor swing videos. Notes This app is not a professional launch monitor or measurement tool like TrackMan or GCQuad. As a video-based visualization app, it does not provide precise measurements such as actual carry distance, spin rate, or ball speed. For a more accurate-looking shot trail, rear-view vertical recording and alignment with the ball position guide are recommended.
