Pretty good

The keyboard is actually pretty good, I personally like that the auto correction isnt super overly drastic when it comes to fixing mistakes. With smaller mistakes it often does not correct them. One might think this is an issue, but really it is kind of a feature in a sense. It gives the user the choice in these cases to let them pick which word they would like it to be. The themes are colorful and add some nice customization to the iPhone for sure. It would be cool though if there were some dark themes which were perhaps more gender neutral. Most of the themes are kind of meant more so for women in my opinion with the super bright colors.
