About BowlTrace: Bowling Analysis
BowlTrace analyzes bowling videos shot on your phone to show the ball's trajectory, speed, and rev rate (RPM). Features • Video analysis — record or pick a video to compute trajectory, speed, and rev rate • Automatic lane calibration — detects the lane, with manual corner adjustment when needed • Arsenal — track your balls' specs and maintenance history • Lane patterns — auto-recognize Kegel standard sheets and visualize the oil pattern on the lane • History — browse your analyses by date on a calendar All videos and analysis data are stored only on your device and never uploaded. Note: The rev rate (RPM) metric is currently in beta; recording at 60fps improves accuracy.
