The Search By Image app allows you to search images which are similar to a reference image. This is for instance useful for finding plant names, mushrooms, animals, people, products, and other things. The app supports Google, Microsoft Bing, Yandex, and Baidu image search.

The app works as follows:
1.) Either take a picture with the camera or select an image from the photo gallery.
2.) The image is uploaded to a server via a secure connection and automatically deleted later.
3.) Different options (Google, Bing, Yandex, Baidu) are available for the image search.
