Mematic is a free app that you can use to create memes in the style of Advice Animal. It offers a few other choice memes as well, such as The Most Interesting Man in the world. There's a large variety and the app is very simple. However, there are almost no memes outside of the "pictures plus text" style, and certain other memes are not available from the app as well. Still, the ease of use makes the app attractive by itself.
