Yelp has added the ability to post reviews from your phone to a business page using the “add review” button. Prior to the changes, Yelp users could only draft reviews for being published later. This is especially useful when you want to review an establishment while you are actually there or shortly after. The new version of Yelp will also let you see photos from each business with the reviews. Photos can be viewed from the business page using a quick swipe down.
