StackTrack takes the guesswork out of spotting for CRW jumps. Enter your drop zone, exit altitude, and canopy performance numbers, and StackTrack calculates your optimal exit point using real-time winds aloft data - so your canopy arrives at the target, not half a mile downwind. How it works StackTrack fetches a live upper-air wind profile for your drop zone from Open-Meteo and runs a simulation from exit altitude down to breakoff. It accounts for wind speed and direction at every 1,000 feet, your canopy's forward speed, and your descent rate to place the exit point exactly where it needs to be. Features • Real-time winds aloft - automatically fetched for any location worldwide • Interactive satellite map with flight path, jump run line, exit point, and altitude markers every 2,000 ft • Lateral and along-track offset sliders to fine-tune the exit relative to the jump run • Winds aloft table showing direction, speed, and temperature at each altitude • Forecast mode - step forward or backward in 1-hour increments to plan ahead • Supports imperial and metric units, multiple speed units (mph, knots, km/h, m/s) • Weather screen with full forecast for your drop zone • Draw generator for 2-way and 4-way sequential
