How to Use Rack Reader
📷 Camera & Scanning
📷
Start Camera
Activates your camera. Point at the pool table from above or at a playing angle.
⚡
Auto-Scan
When enabled, captures automatically when balls stop moving. Perfect for tripod use.
🎯
Scan Now
Manually captures the current camera frame instantly.
💡 Tripod tip: Mount phone overhead, set sensitivity to 5, still delay to 1.2s. App scans automatically every time balls stop.
🤖 AI Detection
🤖
AI Detect Button
After capturing a frame, tap to automatically find and mark balls. AI markers show a purple "AI" label.
📊
AI Confidence Slider
Low (10-30%) detects more balls. High (60%+) only places very confident markers.
💡 Best results: Shoot from above in good lighting. If AI misses balls, lower the confidence slider or mark manually.
🎱 Marking Balls
⚪
Cue Ball
Mark the white ball first. The app draws aim lines FROM the cue ball to your target.
🔴
Solid & Stripe
Mark your object balls. The app picks the closest one to the cue ball as primary target.
🕳️
Target Pocket
Mark where you want to pocket the ball. Unlocks cut angle, aim lines and ghost ball.
↩
Undo & Clear
Undo removes last marker. Clear removes all markers. X discards the frame entirely.
💡 Workflow: Mark Cue Ball → Target Ball → Target Pocket → Suggest Best Shot.
