WhatDog is an Android application developed by Arjun Sunil that uses advanced machine learning and image recognition technologies to identify the breed of dogs in real-time. The app supports 120 different dog species, and the detection occurs entirely on the device, ensuring that your data is safe and secure. If you have a pure-breed dog that the app fails to identify, you can send a few photos to the developer, and they will train the app to recognize the breed.

To use the app, you need to grant camera and file access permissions. Without these permissions, the app will not work correctly. The app is free to use and falls under the education and reference category, specifically books.

The app's interface is simple and easy to navigate, with a camera button that captures an image of the dog. The app then processes the image and provides the breed's name and the confidence level of the prediction. It's an excellent app for dog lovers who want to know more about their furry friends. However, please note that only pure-breed dogs will work correctly with the app.
