Amazon Product Rank allows you to keep track of your product/app performance on Amazon.com. It is as simple as entering the Amazon Standard Identification Number (ASIN) that can be located on the product details page on Amazon.com and entering it in the app. From here the app will retrieve the product sales rank on an interval that you can set/change under preferences. Once you add an item you can hide/delete/view in browser by long pressing on the item. Amazon Product Rank is great if you have items listed on Amazon.com or on Amazon’s App Store and you want to keep track of sales ranking without having to visit the website each time.
