TrajectoryX

Golf Analytics & Training

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

The app for the most advanced, accurate, reliable, complete and trusted launch monitor as well as for one of the cheapest launch monitors on the market. You want to use your GCQuad, QuadMAX 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. New in 6.0 — AI Coach: get instant, data-driven coaching on your practice. Analyze a whole session with one tap — a clear summary with an overall grade, your strengths, what to improve (each tied to the exact numbers) and a targeted drill — or turn on optional live feedback after every shot. Bring your own API key (Claude, ChatGPT or Gemini); you choose the provider, model and language. You can also connect a GCQuad/QuadMAX and a Garmin R10 at the same time, with a connection indicator that shows which device is linked. You wonder why values in the app are not 100% identical to the values displayed on your GCQuad/QuadMAX or FSX2020: 1. Purchase a subscription of the new Foresight-like 'Trajectory Model+'. 2. Go to Settings -> Environments and select the 'Foresight App' environment. The app cannot be used together with GC3 because in contrast to GCQuad/QuadMAX it uses an encrypted UnlockDevice message. 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 are available for Garmin R10 owners as well — now with optional AI-powered session analysis on top. 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/

TrajectoryX 6.0 — AI Coach Get instant, data-driven coaching on your practice. TrajectoryX can now send your range and drill data to an AI of your choice for analysis: - Analyze a whole session with one tap: a clear summary with an overall grade, your strengths, the areas to improve (each tied to the exact numbers), and a targeted practice drill. - Optional live feedback after every shot: a compact banner shows what happened, the main issue and a swing cue — without interrupting your practice. - Bring your own API key (Claude, ChatGPT or Gemini). You choose the provider, model and response language; usage is billed to your own account. Also in this release: - Connect a GCQuad/QuadMAX and a Garmin R10 at the same time: the connection icon now shows which device is connected and stays green as long as at least one device is connected. - New Garmin R10 (E6 Connect) connection indicator — green when connected, red when the connection drops. - The on-screen keyboard no longer hides input fields while editing a drill. - Improved landscape layout for the single data point view.
