BaySpeed turns your Topgolf bay into a ball-flight lab.
Topgolf shows you where the ball landed. BaySpeed reveals how fast it was going when it left your club, how high it flew, and how much of that distance was carry vs roll — all reverse-engineered from your existing game history through a physics simulation calibrated against Toptracer data.
Sign in with your Topgolf account and import your full history in seconds. Every shot gets analyzed: ball speed in mph, launch angle, descent angle, carry vs roll breakdown, kinetic energy, and impact force.
WHAT YOU GET FREE
— Sign in with Topgolf and import your full game history
— Your 3 most recent sessions, fully analyzed
— Tap-to-inspect trajectory replays color-coded by speed
— Speed distribution chart for every session
— Per-shot impact physics: ball speed, launch angle, force, kinetic energy
— Sample data mode if you want to explore before signing in
UNLOCK PRO (one-time purchase, no subscription)
— Full session history, not just your 3 most recent
— Personal records across speed, distance, energy, impact force, and session score
— Improvement trajectory — track your gains to the mph per session
— Recent form vs prior — see if you're hot right now
— Momentum — acceleration phase and current improvement streak
— Milestones — the first time you crossed 70, 80, 90, 100, 110 mph
— Forecast — when you'll hit each speed tier if your pace holds
— Total energy delivered — kilojoules of kinetic energy across every shot
— Speed percentiles — p50, p75, p90, p95, p99
— Shareable stat cards for any section
HOW THE PHYSICS WORK
BaySpeed runs a Newtonian trajectory simulation with quadratic drag, Magnus lift, and spin decay, then binary-searches for the ball speed that produces the measured Topgolf yardage given your bay floor height. The drag coefficient is speed-dependent and calibrated against Toptracer ground truth. Speeds are estimates (±10-15%) — not the same as a launch monitor, but a lot more interesting than just yardage.
