Old Age Maker is a prank app, that allows users to change the age of their face using an artificial intelligence (AI) algorithm. The app's AI analyzes photos, which are then altered using a neural network, resulting in an image with a different appearance. The app uses Google's Face API to calculate the user's age from a single image.

The app is designed to be fun and make a prank, so it can also be used as a way to demonstrate the process of AI, neural networks, and face recognition. It's a cool app to have fun with your friends.
