This app has some advantages over competitors. It is a mix of Instagram and Aviary. Especially once clear and easy to use, which most are not, in my view. Converts quickly to order errors. App is in German and clearly. For symbols always stands what it is. So one does not know, for example, with some other apps what it means a long line with asterisks about it -. That does not happen with this one, because exactly this is to what function is. The only thing that the app can not (such as Aviary and Instagram also not) that is umkonvertieren in Pencilzeichnungen. For this I can among the many different providers then recommend "XnSketch" ... then the image processing heart of every image processing Junkies is met. :-)
