The app would be great if the 'edit skin' button actually worked instead of taking you to the App Store to buy a skin creator app! Also, if you could add more skins to the app that'd be great because there isn't a lot to choose from and a lot of the ones there are kind of weird.
Also, note to everyone writing reviews about not being able to upload skins to PE edition, that's because you CANT upload skins to PE edition! So stop bugging the creators of the app about it, and go bug minecraft about it. Thank you.
