Golf training, a camera-based launch monitor and a 3D driving range, on the iPhone you already have. Every shot detected, the ball measured from video when it can be, your numbers read out loud, the flight replayed on the range. No buttons, no extra sensors. Free for 5 training sessions, then FG Vector Pro (annual subscription, sold in the app).
HOW IT WORKS
Put your iPhone on a tripod three steps behind the ball; FG Vector checks the light and talks you through the setup. Wait for "Ready to play" and hit. The app records the swing, measures the ball and tells you the result. Apart from changing clubs, you don't touch the phone.
WHAT YOU NEED
Daylight or good lighting (indoors into a net too), white balls, sound on (AirPods work too) and a tripod. FG Vector is a camera system: when there isn't enough light to measure the ball, it tells you and waits.
YOUR SHOT, FROM VIDEO
Ball speed and launch measured from video; carry, total and apex calculated from them. Club speed and smash factor are estimates from ball speed and typical values for your club. Plus your shot shape. When the ball couldn't be measured, the shot is marked ≈ and estimated from your usual shots with that club. The numbers are made for training: follow your trends and typical carry, not single shots.
DRIVING VIEW
Every shot with numbers flies again on a photorealistic 3D driving range, built from its ball speed, launch, apex, carry, total and start direction. Watch from behind the golfer or follow the ball, in four seasons, with a golf course around it. Shots stay on the range even after you delete their videos. Compare clubs in your session's dispersion with flight curves; share a picture or a video of the flight.
YARDAGE GUIDE FROM YOUR OWN SHOTS
The typical (median) carry and total of every club, in yards or meters, with the middle half of your shots. Distances are for the balls you hit; Course ball view estimates your own ball.
TRAIN WITH A PLAN
A season goal, a training plan that calls out the next club, and challenges against the app. Challenges count measured shots only.
APPLE WATCH AND GARMIN
Numbers on your wrist; change clubs without walking back to the tripod. Apple Watch adds swing tempo and a Golf workout saved to Health, with your permission. Compatible Garmin watches show your numbers and clubs.
