Google Tasks is a productivity app that works with all of your Google products, including Gmail and Google Calendar. When you sync your Google Tasks account to your iPhone, you can ensure that each to-do list is close at hand. Depending on your preferences and workflow, you can customize the way you use Google Tasks on your iPhone.

About Google Tasks

Google Tasks is a simple list application that allows you to create to-do entries by typing in tasks or adding emails as action items. The service allows multiple to-do lists, subtasks, task prioritization, and printing. Once you've completed a task, you can check it off as completed. Like other Google applications, Google Tasks stays current across all of your devices; whether you update a task on your computer or your iPhone, it will be up to date.

Mobile Tasks

According to Google, the easiest way to access your Google Tasks lists on your iPhone is to visit gmail.com/tasks from a Web browser. If you are not logged in to your Gmail account, you will be prompted to enter your username and password. From the mobile Google Tasks screen, you can add new tasks, check out all of your lists, clear completed tasks, and edit lists.

Mobile Apps

If you prefer to access your task list using an app rather than a Web browser, the Google app is an ideal choice. Once you download the app, click the "Apps" button in the lower left-hand corner and tap on the "Tasks" section. A number of third-party developers also offer apps that are designed solely for Google Tasks; simply sign in with your Google account and the apps will import your data.

Sync with Calendar

If you use your iPhone's calendar, you can configure it to import time-sensitive items from Google Tasks. Before you can do so, your Google calendar must be synced to your iPhone calendar. To get tasks to show up on your calendar, simply add a due date; the task will appear on that date on the calendar.
