Add the Reminders widget to the Lock Screen to see your next reminders. To see only the one task that you must do now, add the widget of [One Task](https://sindresorhus.com/one-task), which shows one task at a time.

## With One Task

1. Open [One Task](https://sindresorhus.com/one-task), and add the tasks that you want to do today.
1. Lock the iPhone, touch and hold the Lock Screen, and tap “Customize”.
1. Tap “Add Widgets” (or the row of widgets, when it already has widgets), and choose One Task. Tap its widget to add it.
1. Tap “Done”.

The widget shows one task. Tap the widget to complete the task, and the next task shows. One Task is not a full to-do app: it works best with only the tasks for today.

## Without an app

The Reminders app has a Lock Screen widget:

1. Touch and hold the Lock Screen, and tap “Customize”.
1. Tap “Add Widgets”, choose Reminders, and tap its widget to add it.
1. Tap “Done”.

The widget shows your next reminders. This is the better way when you want to see more than one task, or when your tasks are already in Reminders.
