"I personally use several of the PunkStar Studio iPhone/iPod applications. Some, like the Cold Air Calculator, are incredibly useful for even the most advanced pilot, while others, like the Hold Pattern Calculator, are perfect for demonstrations with my students (who are thrilled when they see it for the first time). I'm a loyal customer/user of several of the PunkStar Studio apps (even non-aviation related) and look forward to their future releases. I highly recommend their products to all aviators, from the professional airline pilot and flight instructor to the casual pilot."
