Be the first to know when we launch. No spam, ever.
FlushLab is a free, browser-based analysis tool that takes raw launch monitor data and runs it through actual impact mechanics — coefficient of restitution, D-plane ball flight laws, spin loft calculations, and tour-calibrated optimization matrices. Upload a session from any major launch monitor brand and get insights that go way beyond "swing harder."
10 analysis tabs · every feature backed by real physics
Real formulas for ball speed, spin, and carry — not lookup tables. Based on COR, head mass, loft, and measured impact conditions.
Core EngineCorrected ball flight laws with face angle and club path inputs. Per-club shot shape classification, starting direction calculation, and visual flight diagrams.
New in v4.5Full-bag carry visualization with automatic gap identification. Overlap warnings, large-gap flags, ideal thresholds per club pair, and weather-adjusted distances.
New in v4.5Interactive matrix mapping ball speed × attack angle to carry distance. Now with multi-club AoA analysis across your full bag and personalized spin loft deltas.
Enhanced in v4.5Estimates dynamic loft from launch data, calculates spin loft per shot, and predicts spin rates. Trend visualization tracks your spin loft across a session.
New in v4.4Compare up to 7 drivers or 6 wedges with composite scoring across carry, consistency, launch optimization, and spin control. Automated recommendations.
Fitting LabsAdjusts carry predictions for elevation, temperature, humidity, and wind. See how your distances shift from sea level to 5,000 feet or a 40°F morning round.
New in v4.5Auto-detects and imports CSVs from 6 launch monitor brands plus Foresight PDF reports. Save sessions, export JSON, and generate shareable text reports.
6 Brands + PDFWith a conforming driver (COR 0.83, ~200g head, ~10° loft), the physics cap on smash factor is approximately 1.465 — not the mythical 1.50. Even at an extreme 5° loft you only reach ~1.48. Shorter clubs cap much lower: a pitching wedge tops out around 1.06. When a launch monitor reads above 1.50, that's measurement error — not a superhuman strike. FlushLab calculates the real limit for every club in your bag.
