Reviews are currently only available on a show’s Stitcher page on the web. The best way to find a show’s Stitcher page is to enter a Google search using the show’s name + "stitcher." For example, "This American Life Stitcher" would return the result:http://www.stitcher.com/podcast/this-american-life
You’ll be able to leave a review once you’re on the show’s Stitcher page. Our team is considering bringing this feature to the mobile platforms in the future.
