Apple’s iOS 15 is available for iPhones and iPads. Here’s what you need to know.

After 18 months of days blending into nights, weeks into months, months into years, it’s hard to know when work stops and life picks up anymore. Focus is a tool that lets you block communications from people or apps depending on what you’re doing, like working, sleeping or spending time with your family. It’s an extension of the existing Do Not Disturb option, and you can customize defaults or make your own. It also takes a cue from Slack and will tell people who message you that you won’t see notifications, though they can barge through any way. Focus is an optimistic feature that believes people can create healthier boundaries in their life with a little technology.
