The first developer beta of iOS 15 was released on June 7, 2021, and the first public beta was released on June 30, 2021, six days after the release of the second developer beta. iOS 15 was officially released on September 20, 2021.



The Focus allows users to set their "state," such as work, sleep, do not disturb or a custom focus. Based on the selected state, users can set the type of notification they want to receive and from which application. It is also possible to choose which pages and then apps to show on the Home based on the state. The state can change automatically based on where the user is or a time. Focus also controls the interactions with Contacts, so it is possible to decide which specific contacts can "disturb" the user. Some Lock Screen settings can be controlled based on the state: for example, the Dim Lock Screen feature, which darkens the lock screen from not showing notifications on that screen, can be automatically turned on or off based on the state. Focus is synchronized automatically across different iOS and macOS devices on the same iCloud account, as well as any paired watchOS devices.


Notifications receive a new look with contact photos for all communication apps and larger app icons. When the notification arrives, the user can mute the corresponding app for one hour or all the day. The Summary allows the user to group and postpone the notifications coming from the chosen apps, delivering them at a scheduled time in a single big notification called summary notification.

Smart stacks with suggested Widgets

The Widgets in iOS 15 are more dynamic: depending on the context, the system can add or remove widgets to existing stacks.
