Practice Deck for the iPhone comes in handy.
Practice Deck is based on a training tool from DR Performance Shooting. Using a deck of cards theme, the iPhone app provides 52 different shooting drills from which to choose. The drills are categorized by specific skill sets, such as Draw, Reload, Barricades, Strong Hand Only, Transitions, etc. The user can pick a specific drill, or "deal" one out randomly. Each drill shows a diagram of the stage layout and gives brief instructions.
The drills are a pretty simple to set up. They require at most three targets, a couple of barricades, and a shooting box marked on the ground, and are designed to be used with standard USPSA or IDPA targets. The author gives a simple "time plus" scoring suggestions for tracking your practice and improvement.
One additional feature I'd like to see added is the ability to record my scores on specific drills over time. The Practice Deck website mentions a future feature to track scores via the website. We'll have to wait and see how that is implemented.
Practice Deck is available in the iTunes store as a free download with a limited number of cards. An in-app purchase unlocks the full deck. If you are looking for more variety for your trips to the range, try it out.
I purchased the Practice Deck app of my own free will and received no compensation for this review.
