What is "facetune"

Facetune is a photo editing application (“app”) used to edit, enhance, and retouch photos on a user’s iPhone, iPad, Android or Windows Phone device. The app is often used for (yet not limited to) portrait and selfie editing[9]. Features allow users to whiten teeth, remove blemishes, smooth skin, reshape, defocus and blur. Facetune users can also choose from a variety of filters, lighting, textures, contrast, and frame options. Demo photos are downloaded with the app for practicing purposes, and a help button is found within each feature. Facetune enables users to share their pictures on a variety of social networking services, including Facebook, Twitter, Tumblr, Flickr and Instagram.
