Google Tasks is a basic to-do list app that offers features like lists, subtasks, and mobile notifications, making it an essential tool for keeping track of important tasks, especially for those who already use Google Workspace apps like Calendar, Gmail, and Docs. To access Google Tasks, users can click the icon in the side panel of various Google apps or download the iOS and Android app. Once open, users can add tasks by clicking "Add a task" and giving it a title, adding details, setting a due date, and repeating it if needed. The app also allows users to edit tasks, archive emails, and manage their to-do list using sorting methods and lists. Additionally, Google Tasks integrates with Gmail, allowing users to drag and drop emails to transform them into tasks, use keyboard shortcuts, and even automate tasks by connecting it with Zapier.
