In this podcast from his series looking at some of what's new and notable in iOS 15, Thomas Domville Shows us how to setup and use Focus modes.

Focus is essentially a supercharged upgrade of Do Not Disturb. This is how Apple describes Focus:

Focus helps you stay in the moment when you need to concentrate or step away. Choose a Focus that allows only the notifications you want — you can get work done while you’re in the zone or enjoy a distraction‑free dinner. Pick from a list of suggested Focus options or create your own.

What do you want to focus on? Choose a focus area to set up: Custom. Driving. Exercising. Gaming. Reading.

Stepping away is easier if others know you’re busy. So when you’re using Focus, your status will be automatically displayed in Messages. And for truly urgent messages, there’s still a way for people to notify you.

Key feature highlights of Focus are:

• Allow notifications only from certain people and apps.
• Time-sensitive notifications.
• Presets: There are presets for different parts of your day: work, personal time, workouts, and more.
• Dynamic home screen allows you to only show particular home screen pages when a Focus mode is enabled.
• Cross-device sync.
