Need to Personalize user experiences in app

It would be great if you could personalize your app to you. Like uploading a profile pic, be more thorough with before and after pics. Why not make it fun and interesting by adding a photo app to make collages of before and after photos and folders for weekly or monthly updates of body photos? 

You could also incorporate some fun workout routines to suggest and helpful tips and tricks curated just for app users personally itemize to their needs and wants. This app could be so much more effective and useful if you just add a few things make it more user friendly and add some personalized details that will make it special and personal to that app user in general. Even add some weight loss games make it fun. Make it stand out from other apps.
