You want to use your Foresight GCQuad, QuadMAX, GC3, GC3S, TrackMan 4, Full Swing KIT, 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, watch it back in slow motion and compare two swings side by side, and get instant AI coaching on your practice (not available in mainland China). See your ball flight in 3D. The 3D Range replays every shot in a photorealistic driving range built from your launch monitor's shot data — follow the ball with a live tracer from behind, down the target line or overhead. Just pick the "3D" view on the range. Turn any data tile into a challenge. Set a corridor on a tile and choose its game: count your streak, reach a target of hits in as few shots as you can, chase your highest or lowest value, or beat the clock. Combine several tiles into one challenge — a shot counts when every tile is inside, or as many as you choose — and keep your personal records across sessions. Know your real shot pattern. My Bubble measures, per club, where your average ball lands and how far you actually miss long, short, left and right; the Aim Planner lays that pattern over a green and shows the "% on the green" while you slide your aim. Study your swing in the new player: the video fills the screen, tabs jump to Address, Top, Impact and End, pinch to zoom, trim, draw, loop and change the speed — and Swing Compare plays two of your shots in step, with the data points A, B and B − A underneath. A home screen widget shows your last session and opens your newest swing video with a tap. Works with Foresight GCQuad, QuadMAX, GC3, GC3S and Bushnell Launch Pro, TrackMan 4 (connected directly over Wi-Fi, incl. swing videos from its camera), the Full Swing KIT (over Bluetooth) 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 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. Today the same drills and training features are available for QuadMAX, GC3, Bushnell Launch Pro, GC3S, TrackMan 4, Full Swing KIT, 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 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/

Verdict
The clearest difference is in-app purchases: Readout Golf at none against TrajectoryX's 3. Readout Golf also leads on iOS requirement (14.0.0 vs 17.0). TrajectoryX's advantage is update cadence (every 10 days vs monthly). On price, ads and device support there is nothing between them.
