Tap the + icon below Allowed Apps and choose any app you want to receive notifications from. Alternatively, if you don't want anyone to disturb you at all, tap Allow None. You can allow calls from everyone, or just your favorites? You can also toggle on alerts for anyone who calls you twice within three minutes. Below, you can also choose how calls behave. Tap the + icon under Allowed People and tap a contact's name to add them. For the purposes of this how-to, we're sticking with Custom. For example, Gaming Focus can automatically turn on when you connect a wireless controller to your device, or Fitness Focus can be triggered when you start a workout from your Apple Watch. Pick one, or tap Custom to make one from scratch. On Macs, head to System Preferences > Notifications & Focus and tap the + icon on the bottom left. Or you can go to Settings > Focus and tap the same icon at the top right.
Tap the + sign at the bottom of the Focus page in the Control Center.
