BAL.ON – the Foundation of Fast! BAL.ON is a mobile golf training system refining details of your swing technique to unlock higher club head speed and achieve lower scores. It relies on pressure and video data to analyze your motion along key metrics. Based on your scoring in these metrics, BAL.ON’s AI coaching recommends the one individual drill to fix your swing. You improve your technique, swing faster, hit it longer. Customized feedback, better shot The BAL.ON app records your pressure data and videos of your swings. It compares both with thousands of reference data, many of them from pros. Out of this, BAL.ON spots your chance for improvement. Relying on swing metrics and AI, you get customized drills that help you swing faster and hit longer shots. Take apart your swing, then your opponent BAL.ON rates your swing along three basic metrics: Setup, Backswing, and Impact. Mastering these swing key positions improves your ball-striking quality and consistency. The advanced metrics are Transition Timing, Vertical Timing, Max Vertical, and Rhythm. Understanding and perfecting the timing minutiae within your weight shift gives you the extra momentum for clubhead speed and ultimately shot length. It also helps achieve the effortless grace that advanced players look for in the golf swing. How BAL.ON delivers for you as a coach Live heatmap Have pressure distribution visualized throughout the swing. Center of pressure See the combined center of pressure, a key variable for shot quality, move during the swing.

You want to use your Foresight GCQuad, QuadMAX, GC3, GC3S, TrackMan 4, OpenFlight or Garmin R10 for Trackman Combine Tests and in your daily range, driver, chip and pitch training? With this app you can execute predefined drills, tailor them according to your needs or configure your own drills. In addition you can display and visualize launch, ball, club and trajectory data on the range, record your swing and watch it back in slow motion, and get instant AI coaching on your practice. See your ball flight in 3D. The new 3D Range replays every shot in a photorealistic driving range built from your launch monitor's real trajectory — follow the ball with a live tracer from behind, down the target line or overhead. Just pick the new "3D" view on the range. New in 8.3 — even more launch monitors. Works with Foresight GCQuad, QuadMAX, GC3, GC3S and Bushnell Launch Pro, TrackMan 4 (connected directly over Wi-Fi, incl. swing videos from its camera) and OpenFlight, plus Garmin Approach R10 (E6 Connect). GCHawk and Falcon support is experimental. The Bushnell Launch Pro and GC3S speak the same protocol as the GC3, so they connect exactly the same way. Great on iPad. Run TrajectoryX side by side with other apps in Split View or a freely resizable window — every screen adapts to the window size, drills show their score sheets side by side when there is room, and the split range can even replay your shot from two camera perspectives at once. You wonder why values in the app are not 100% identical to the values displayed on your GCQuad/QuadMAX/GC3/... or FSX2020: 1. Purchase a subscription of the new Foresight-like 'Trajectory Model+'. 2. Go to Settings -> Environments and select the 'Foresight App' environment. I started implementing this app because I could not find anything in the app store to connect reliably my iPhone with a GCQuad/QuadMAX. Today the same drills and training features are available for GC3, Bushnell Launch Pro, GC3S, TrackMan 4, OpenFlight and Garmin R10 owners as well. Please let me know if you have any problems with the app: info@TrajectoryX.com Privacy — AI Coach (optional): AI analysis is off until you add your own API key. When you enable it, your shot and session numbers (no personal data) are sent to the AI provider you choose — Anthropic Claude, OpenAI ChatGPT or Google Gemini — to generate feedback, handled under that provider's privacy policy. Your API key is stored only on your device. No data leaves your device unless you turn this on. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
