About

Nine Windows

Features
Read full description

Nine Windows is a golf practice companion that helps you train all nine shot shapes — high, mid, and low trajectories combined with draw, straight, and fade shapes. Each practice round gives you a random distance and one of nine target windows on a 3x3 grid. Your job is to hit the shot. Record whether you nailed the distance, the window, both, or missed entirely. FEATURES • Random Shot Challenges Get a target distance and shot window for each attempt. No two practice sessions are the same. • Session Tracking & Duration Record each shot result and see your accuracy percentages for distance, window, and both combined. Session duration is tracked automatically so you can see how long you practiced. • Session Notes Add free-text notes to any session — record what you were working on, course conditions, or tips from your coach. Notes appear in your session history for easy reference. • Practice Goals & Streak Goals Set targets for accuracy, shot count, or consecutive hit streaks and track your progress over time. For accuracy goals, choose how many shots must be recorded before the goal can complete — so a lucky first shot won't count. For streak goals, pick which result counts as a "hit": Both, Distance, or Window. Goals can be scoped to all time, recent days, recent sessions, or even your current session. Progress updates live as you practice, with a celebration when you hit your target. • Data Export (CSV & PDF) Export your session history as a CSV spreadsheet or a professionally styled PDF report. The PDF includes a visual summary with accuracy cards, progress bars, and a session history table — perfect for sharing with coaches or reviewing your progress. • Focus Mode / Weak-Area Drills Activate Focus Mode to drill the windows and distances where you struggle most. The app analyzes your shot history and biases challenges toward your weakest areas. • Detailed Stats & Insights View your overall accuracy across all sessions. See your strongest and weakest windows, best and worst distance ranges, and all-time best streak. Trend indicators show how your last 5 sessions compare to your previous 5. • Window Performance Heatmap See your accuracy for every window in the 3x3 grid at a glance, color-coded from green to red. • Trajectory & Shot Shape Breakdowns Track your accuracy by height (High, Mid, Low) and shape (Draw, Straight, Fade) to find patterns in your game. • Driving Range Management Save multiple driving ranges with their flag distances. Practice with the exact distance markers available at your range. Per-flag accuracy stats show which distances you're nailing and which need work. • Yards or Meters Switch between yards and meters in Settings. All distances, stats, and flag markers convert automatically — perfect for international golfers. • Customizable Stats Display Long-press the session stats area to reorder and hide stat sections. Drag to rearrange, tap to toggle — your layout is saved automatically. • Streak Milestones Build consecutive "Both" hit streaks and get celebratory feedback every 5 in a row. Your all-time best streak is tracked across sessions. • Warmup Routines Start each session with a structured warmup. Use the built-in 65-shot routine or create your own custom routines with configurable distance ranges, target windows, and shot counts per phase. • Distance Variance Choose from three variance levels to add realistic randomness to your target distances. • Apple Watch App Take Nine Windows to the range on your wrist. Get shot challenges, record results, manage driving ranges, and track stats right from your Apple Watch. • 20 Languages Fully localized in English, Arabic, Chinese (Simplified & Traditional), Danish, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Malay, Portuguese (Brazil), Spanish, Swedish, Thai, Turkish, and Vietnamese.
