Before & After Camera allows you to:
• track you fitness goals
• track your pregnancy progress
• take a photo based on another photo
• document child growing up
• .. and many more
Every time you take a photo, the application will allow you to see the previous one in the camera preview window, so you don't have to remember how exactly the previous one looked like. This will allow you to better compare them later as you can make them look very similar.
Applications can work with photos taken by the app or any photos from your gallery. Photos taken with the app are saved in a way, that they can be easily edited or shared with other applications or backed up by Google Photos.
We respect your privacy. We never upload photos from the app to our servers. Everything stays on the phone unless you decide to use Google Photos to back them up, but this will happen only if you explicitly set Google Photos to back this directory up.

Note that this is NOT a photo editor. There is a lot of other applications that allow you to combine few photos together including ones, that are taken by this app.
