Google Photos is an app that uses a machine learning system. The application has been available since April on Google smartphones. However, it is now available for iPhone users as well. The Google photos app uses a feature call Google Lens – to search Google’s enormous amount of data to identify information from the photograph to provide additional, useful information. For example, take a photo of the menu the next time you’re in Mexico, and use Google Lens to translate the text into English for you.
