Golf Tempo
Golf Tempo is an iPhone golf swing tempo trainer, with a free online trainer at mygolftempo.com. Three audio cues mark the start of the swing, the top of the backswing, and impact, so you can practice a steady 3:1 or 2:1 rhythm without watching the screen. Built-in Short Swing (2:1) and Long Swing (3:1) modes each have nine adjustable tempo levels, and you can create custom ratios. The free browser trainer needs no sign-up.
