It's an Etsy seller tool (not affiliated with Etsy) that pulls info from Etsy and Google Analytics.
The "Shop Lover" section shows you how many visitors you've had to your shop/individual sessions, sales $ amounts, shop hearts, and item views and hearts each day (on a calendar).
The "Tag Report" section shows you which of your item tags brought people into your shop/to an item and what page of the search results your item was on.
The "Edit Express" section lets you change multiple item prices, titles, descriptions, and quantities at the same time. I haven't used this one yet, so I don't know how well it works.
