Track progress: Before and After Images: helps you track progress, save photos to compare changes of anything you care about, or simply an app to save your secret images using a password. Main feature: Track progress: Track your body's changes, your pet's growth, flowers... Secret Image: Storing secret images, the images are completely inaccessible from outside the app, so you can completely secure these pictures. Before and After Image: compare any 2 images, zoom up to 30x so that you can see any pixels, export, share and edit the compared images. Private: Using a password, fingerprint, face, or iris to unlock the application, no one can access it but you. Import images from the Photo Gallery, external storage, google driver... Save photos back to the gallery, share anytime you want. Export images to help you backup data. Thank you for using my application.
