Today our highest rated ecommerce platform of 2012, Shopify, announced a new free Apple iPad shopping app that lets anyone in the world explore and purchase all the products (5 million) selling on Shopify’s +35,000 online stores.

Catalog is a “smart iPad shopping app” and is engineered to learn your shopping preferences and tailor it’s search results to your interests.

Here’s a screenshot of Catalog’s homepage:

Shopify predicts that by Christmas 2013, 43% of all ecommerce purchases will be made on a tablet or smartphone – so this is their way of helping their merchants tap into mcommerce and all the potential customers shopping on their iPads.

This is an aggressive entrance into the world of online marketplaces, like Etsy, FAB, and Gilt. Shopify’s merchants will surly enjoy this new steam of customers, and I suspect other ecommerce platforms may consider opening their own marketplace.

At first glance, the shopping app looks really good. What do you think?
