For well over 100 years, people have shopped using catalogs they received in the mail. Although online shopping has more or less supplanted the mail order business, a catalog is still a great way to see a large variety of products from the comfort of your sofa. The iPad allows shoppers to continue this tradition without killing any trees, and affords retailers an opportunity to revamp their catalogs into something that doesn’t look like it’s 100 years old. Some apps so faithfully recreate paper catalogs that it feels as if you are turning pages. Other apps reimagine the concept of the catalog or offer entirely new paradigms. Whichever type of app you choose, you’re sure to find something to help with your shopping needs!
