I had been a huge fan of the free version of Pack the Bag, uploaded it to my old iPhone 3GS, and using it on a number of my trips to help me organize. I held off for a while before taking a chance on the pay version, wondering if I would not only like it better, but if it would be as flexible and efficient as the original. I had some extra iTunes gift dollars and decided to give it a go. Im only thankful the free version still exists. After several attempts for vacations last year, I gave up and returned to my tried and true. For one, the pay version appears more complicated than the first, which is ridiculous. Im big on categories and subcategories, and I was never sure if I was adding something to be packed later, or what was happening, as I seemed to be going thru way too many clicks to add one item. Even deletions were complicated due to swipe attempts which werent always successful. I liked the idea of being able to "pack" an object in a specific bag youre taking, but even this got frustrating. The only thing I did like was the weight section; when one has to be careful not to overpack due to baggage fees, etc. this was the one helpful benefit. After consulting the instructions numerous times, I finally contacted the designer by email AND even on Facebook, but despite their answers, I was never able to achieve their claims. In the end I removed the pay app and reinstalled the old one. It wasnt worth the trouble.
