Phone-only launch monitor
Hit a real ball and the phone's camera measures your launch — ball speed, carry, launch angle, start line. No radar, no sensors, no wearables required.
A golf simulator and driving range that runs entirely on your iPhone. Hit a real ball, face-on to the phone. The camera reads your launch, and the shot flies out onto a photoreal course rendered on-device.

How it works
Rendered on-device
Ball flight and the course are rendered right on the phone. Nothing is streamed from a server to draw your shot.
Range & simulator
Warm up on the driving range or play a round on a course built from real-world terrain. The phone stays on its stand and the course plays on a bigger screen: an iPad on the same Wi-Fi, a TV over an HDMI adapter, or a laptop browser at swingseason.app/display. Second screens and Apple Watch
What you need
A stand for the phone, a white golf ball, and a net or open range. Light on the ball matters most: daylight or a bright lamp. A dim room blurs the ball in flight and swings won't read.
Every number on screen is a measurement taken from what the camera actually saw — a read either solves and we show it, or it doesn't and we ask for another swing.
