in case you missed it, last month saw the debut of Golf Vision Green Analyzer, an app that uses the iPhone’s accelerometer to calculate the perfect putting angle to sink a ball on the green; just measure the slope angle at the hole and at the ball by laying the iPhone on the ground, then set the green speed, and the app does its magic calculations and overlays the premium angle graphically over a still photo of your view to the hole.
Skeptical? That’s ok, the developers have just released a free version to try before considering the $5 full version. Unfortunately, the free version uses a generic photo to overlay the calculations on, and more importantly, only allows for slope measurements at one end, so results may not be as accurate as with the full version.
