Anime Kiss TV is a free app that's linked with the KissAnime provider of all the latest and most popular shows. It provides access to both dubs and subs, to a huge variety of genres, and to a number of features that the website itself has (or doesn't have).
Unfortunately, there's one thing that can be said about Anime Kiss TV: its selection of anime is not the most comprehensive in the world. Though it boasts over 40 genres, and some of the most popular titles such as Naruto Shippuden or Hunter x Hunter, the truth is that it's missing many obscure titles (particularly those with only one season or less). There's a noticeable focus on shounen anime, as well. Besides that, though, it provides both dubs and subs for almost every series which has both, a favorites feature, and suggestions as you search: all good for finding and enjoying anime old and new.

Basically, Anime Kiss TV is a great choice if you just want to enjoy the most popular anime in the world, or browse through new series as a relative anime neophyte. If you're looking for less popular series, or for something truly fresh and original, it's still worth a try, but Anime Kiss TV shines in that it delivers the content most people will want in the best possible ways.
