I reluctantly bought this app based on the horrible reviews but noticed since the latest update, the reviews improved. Seems the developer put out the app prematurely. Running the app on a iPhone 4 and its very useful but a tad pokey. So far no crashes. Ability to browse a large portion of the Pantone library and explore complimentary pallets will prove very useful in my concept work. Emailing a palette displays all the specs you need such as HexDex, RGB, etc. So far so good. Will report back if it turns on me.
