Google released Google Tasks mobile app
Google introduced a new app that ties into its suite of productivity applications: Google Tasks. The app offers you a dedicated place to create, view and edit your task list and to-dos, including those created from within the new Gmail or from Google Calendar. The app itself is a fairly standard take on to-do lists. You can create and manage your task list in the app, and break down tasks into subtasks. The drag-and-drop interface lets you prioritize your tasks, and you can set a “due date” for reminders on those you don’t want to forget. What makes the app worthwhile is that you’re able to trace a task back to its source email in Gmail, and view them on your Google Calendar.
Google Tasks alternatives are: Google Keep, Todoist, Google Calendar, Any.do, Toodledo, Evernote
