SwingNerds is the companion mobile app to SwingNerds.com and the SwingNerds Vision Windows app. If you record swings in your sim bay with USB cameras and play with GSPro - this is how you review, analyze, and improve away from the bay. Your Whole Game In Your Pocket Every shot from every session, synced automatically. View your full shot library, browse past sessions, and pull up any swing in seconds. Your data stays synced across the web, Windows app, and your phone. All Your Launch Monitors, One View Connect Rapsodo, Uneekor, GSPro, Square Golf, or upload CSVs - SwingNerds pulls it all into one unified dashboard. Filter by club, data source, or date. Sort by carry, ball speed, spin rate, or any of 20+ shot metrics. Watch Your Swings Anywhere Swing videos recorded from your sim bay cameras play back full-screen with 0.1x slow motion, frame-by-frame scrubbing, and angle switching (Down-the-Line, Face-On, Impact). Perfect for reviewing last night's range session on the couch. Side-By-Side Swing Comparison Set a "Standard" swing per club. Any time you pull up a shot, your standard plays alongside it in sync - so you can see exactly what changed when things go off. AI Swing Analysis Get actionable feedback powered by Claude. Analyze any swing for strengths, areas to improve, and specific drills - then ask follow-up questions and get real coaching back. Analyze your whole game over any date range for trends and patterns you'd never spot on your own. Charts, Trends, and Deep Insights Dispersion charts, progress over time, club averages, consistency per club, and all-time career stats. See how each club has evolved from your first session to your most recent. Smart Data Quality Automatically flag partial swings, practice shots, wrong-club selections, and outliers so your analytics reflect your real game. Configurable sensitivity, full control. Record On The Go (Optional) When you're away from your sim bay, record swings directly from your iPhone with automatic swing detection and 60/120/240 FPS capture. Videos auto-sync and pair with your shot data. --- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://swingnerds.com/privacy
