The app allows the user to view a swing of the Professional that accompanies the App, a golf Model, and any other golfer that you choose to set up a profile for. There are drawing tools that help the instructor analyze the golfers swing. Additionally, you can compare golfers side by side. You can also merge a model with another golfer to determine an "ideal position" of a golfer in the conventional golf swing.
Adding a golfer is somewhat cumbersome: I take a video using the another app and take snapshots of various stages of my swing. I then import the swing sequence into the app. Another process I use is access the swing sequences from golf magazines and I import swings of various PGA Tour professionals. You can view swings in various permutations (ie single golfer, series or 24 shot picture), including comparison and merge functions.
Overall, this is an excellent app. However, I recommend the following ideas for updates:
"Play" button to watch sequences
Automate the comparison views
Allow for importing videos from the Library
Option to email or save the Sequence View
Additional Pro Sequences, including various swing styles (ie single versus dual plane, "natural golf" and stack and swing).
