I've been using GolfSense for about 6 months and it's allowed me to focus on improving specific parts of my swing. Because it attaches to your glove you can switch between clubs with a simple touch of the screen. The newer version of the app makes for a better experience and is easier to use. Through analysis I've been able to improve my club plane and tempo. I've also used it to get a feeling for half shots, their tempo and how far the club should go back. The only complaint I have with the new version is that the Club Head speed graph is no longer available. Now it only shows the overall max speed and not where that max happened in the swing. For example, if you see your speed hits its max before impact then you know you're releasing the club too soon. Without this information you can work on increasing your club head speed all you want, but if it's happening before impact then you aren't optimizing the energy of your swing. I'm sure saying that most people want more distance is an understatement. The Golfchannel devoted October to that very topic. Seeing this feature return to GolfSense would be fantastic.
Very pleased with this product, works well with both my Ipad and Iphone. Especially glad they are updating the software continually and I look forward to more data such as attack angle, club face at impact, etc, which should be not to difficult to show, albeit not 100% accurately (I'd just like an approximation).
