Body Transformation Diary with movie export

Do you know all the youtube body transformation movies? People are doing sport and they make a photo of his body every week to see how the body changed from fat to fit. I had a look into the app store and I can't find a really good app where the fitness people can take pictures or can choose one from his camera roll to get a photo diary of his body transformation. important functions: - add a new photo from camera roll or camera - add existing photos, the app detects the original date and sort it into the diary - user can add to every picture the following facts: weight, body fat - user can create a short transformation video from all photos in his diary. The app is generating a movie. Every picture with a duration of x seconds (adjustable by user). He can add music from his "music" iphone app as background. User can add a Title for the movie and he can sent the video per mail, instagram, twitter, facebook and youtube. Please have a look to the attached files and answer only if you are able to do this work.
