iOS 15 is the fifteenth and current major release of the iOS mobile operating system developed by Apple for its iPhone and iPod Touch lines of products. It was announced at the company's Worldwide Developers Conference on June 7, 2021 as the successor to iOS 14, and was released to the public on September 20, 2021.[6]



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.[7][8][9] 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's 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.[10]


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 1 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.

Live Text[edit]

Devices with an A12 chip or newer support Live Text in all apps which can transcribe text from the camera in the real world, images, photos through Artificial Intelligence text recognition using the Neural Engine.[11]

Smart stacks with suggested Widgets[edit]

The Widgets in iOS 15 are more dynamic: depending on the context, the system can add or remove widgets to existing stacks. For example, near the start of a certain event in the Calendar, the system can decide to add the Calendar Widget to an existing smart stack, if it is not already present, and then remove it at the end of the event.

Cross-App Drag and Drop[edit]

Users can now drag pictures and text from one app to another.


Users can now reorder or delete the various Home screens.

Per-App Text Size[edit]

From the Control Center, the text size can be set per app.


The global search function has been enhanced and it is also available on the lock screen by pulling the page down.


Formerly limited to 60 seconds, the Voice-To-Text dictation available in the keyboard is unlimited.[12]

System-wide translation[edit]

System-wide translation allows the user to translate text in all apps by selecting it and tapping on the Translate option.[13]

Adjust video playback speed[edit]

The system default player, used for videos and by many apps, has the control to adjust the playback speed.

Video Effects and Mic Mode[edit]

Video Effects and Mic Mode are two new commands in the Control center that allow the user to add Portrait effect to the camera and set Microphone mode to Voice Isolation on any apps.

Accessibility improvements[edit]

  • Per-App Accessibility: each app can have a different accessibility setting to customize the text (Bold Text, Larger Text, Button Shapes, On/Off Labels, Reduce Transparency), increase contrast, reduce motion, autoplay video-preview, etc.[14]
  • Image Exploration with VoiceOver: it describes photos to give users with low vision more context about what’s displayed on the photo.
  • Audible charts: the Audio Graphs accessibility framework allows to represent chart data with audio for blind and low-vision people.[15]


Backups to iCloud can now also be made on 5G cellular networks.[12]

RealityKit 2[edit]

The new version allows apps to build more immersive AR experiences using new APIs to capture objects even faster, custom shaders, dynamic assets, custom systems and character control.[16]

Increased 5G usage[edit]

iOS 15 allows more apps and system features to use 5G connectivity than iOS 14, including:

  • Downloading apps
  • Backing up from and restoring to iCloud
  • Downloading content from Apple TV+ in higher resolutions

It also allows devices with 5G connectivity to automatically fall back to the 5G connection when experiencing performance issues on unsecured or captive wireless network.

Accounts for School and Work[edit]

It is possible to add to the iPhone the accounts of your organization, managed by schools or companies, without having to use external apps or profiles.

StoreKit 2[edit]

StoreKit 2 allows apps to implement the "Request a Refund" option in-app. The users can tap this option, select a specific in-app purchase and identify the problem that led to the refund request. It also allows developers monitoring the purchases made by their users without using third-party solutions.[17]

App improvements[edit]

  • Multiple images in stack: messages now displays multiple images in a stack, making them easier to navigate.
  • Pinned content: it's possible to pin any content, text or link you receive from a contact.
  • Shared with You: Messages also introduces a new feature called "Shared with You," which organizes links and other content shared via Messages in a dedicated section in their native apps for later viewing (for instance, a news article shared via messages is shown in the News app).[19]


Apple Maps receives several new features:

  • Greater depth has been added to the driving maps with the use of 3D modeling, which will make it easier to interpret directions when faced with roads that go over or under the one being driven on, including buildings, bridges and trees.
  • 3D globe with a new color palette and increased mountain, desert, and forest detail
  • Increased traffic information, turn lanes, bike, bus and taxi lanes, medians, crosswalks

  • Reports and Reviews: you can report incidents, write reviews and add photos to points of interest, etc.
  • New features for driving, including a new map where details such as traffic and incidents are highlighted, as well as an itinerary planner that lets you view a future journey by selecting departure or arrival time.[20]


The Photos app can now manually set the time, date, and location of a photo. The app also allows the user to view information about the photo such as the camera used to take the photo and the photo's file size. [21] In the Photos app, the user can now look up places that are inside images, however, this feature only works on the Apple A12 chip and later.[22]


Improved panoramic shooting mode on iPhone 12 and above: less geometric distortion in panoramic shots with elongated fields of view, noise and banding reduction that are formed in the image due to changes in brightness and contrast when moving the camera from side to side other, a less blurry and clearer image even when capturing moving subjects within the panorama.


Safari was completely redesigned, moving the tab bar and address bar to the bottom of the screen. It now has tab groups, allowing users to organize tabs and share entire groups of tabs.[23] Browser extensions are available for the first time in Safari for iOS; they are the same extensions available in Safari for the Mac.[24] Safari will automatically upgrade HTTP URLs to HTTPS if compatible. The WebM audio codec is supported.

Safari opens with a new start page; it is possible to have a custom page on startup that contains sections including favorites, most frequently visited sites Siri suggestions, etc.[25]

App Clips more discoverable: it is possible to show a full-screen preview of the app clip in Safari.


Weather received an overhaul, with new animations and weather maps in full screen, and the weather icon was updated.

Next-time precipitation notifications: you’ll get a notification whenever rain or snow is going to start or stop within the next hour for your current location and each saved location, independently.


Siri now works offline, offering shorter response times for the most common requests that do not require an Internet connection. Requires A12 Bionic chip or later.

Share with Siri: you can ask Siri “Hey Siri, share this with [name]” (or something similar like “send this to [name]”) and Siri will share the content on the screen to that person using Messages. Items like images, web pages, Apple Music or Podcasts, Apple News stories, and Maps locations will share the actual content (or a link to it). For content Siri can’t share, it will warn you that it can only send a screenshot—but Siri will still automatically take that screenshot and drop it in a Message to that person.

Announce Notifications: with announce notifications update in iOS 15, Siri can now read all incoming notifications and even allow users to respond to them using their voice. The user can choose to enable this for specific apps.


Health data can now be shared.

A new monitored parameter called "Walking Steadiness" has been added, which determines the risk of falling using gyroscopic sensors that measure balance, stability, and coordination.[26]

Added the Trend analysis i.e. horizontal lines that show the trend of the various parameters over the long term.[27]

Lab Results allows you to import laboratory results into the Health app from a healthcare provider.


Groups is a new view mode that groups files of the same type.

The built-in PDF editor can insert pages from existing files or scans, remove pages, and rotate pages. PDFs can also be locked with a password.[28]


New #tags allow classifying, organizing, then finding your notes faster. Smart Folders automatically group various notes based on tags. Ability to share notes with other collaborators and work on them together. The activity view shows a summary of the changes made by other collaborators before your last reading and a day-by-day list of the activities carried out by each collaborator. It is possible to mention @someone in the notes, who will be notified.


Ability to insert #tags in reminders to classify them.


Sound recognition has been added to the automations, so it's possible to execute a customized command when a certain sound is recognized.

Voice Memos[edit]

Added new playback options to adjust speed and skip silence.


Security and privacy[edit]

App Privacy Report[edit]

By activating this app logging, the user can save a 7-day summary of the times when the various apps access certain data and the domains or websites they visit.[31]

Siri improved privacy[edit]

On devices with an Apple A12 Bionic system on a chip or newer, Siri now converts audio into words on the device itself instead of sending it to Apple servers.[32]

Hide my IP for Trackers in Safari[edit]

Safari's anti-tracking now prevents known trackers from reading your real IP address

Hide my IP for External Content in Mail[edit]

In the Mail app, you can enable the setting to hide your IP address when downloading external content that may be present in a mail message. In this way it is possible to privately download this external content without being tracked by spammers or commercial companies that have inserted them without the user's knowledge.

Hide My Email[edit]

Hide My Email creates random email addresses that forward to the inbox so e-mail can be sent and received anonymously.

iCloud Private Relay[edit]

Private Relay masks the user's IP address in Safari, preserving the region without revealing the actual location. It also protects the DNS query resolution and insecure HTTP traffic in all apps.

Built-in one-time password authenticator With Autofill[edit]

The built-in authenticator allows iOS devices to be used to generate verification codes for additional sign-in security of accounts. There is no need to download a separate app because it is integrated into the OS. The verification codes are automatically filled when a user signs in to the site.

WPA3 Hotspot[edit]

Hotspot connections now can also use the WPA3 security protocol.

CSAM detection[edit]

CSAM detection[33] identifies known Child Sexual Abuse Material (CSAM) in iCloud Photos accounts. This recognition is based on a perceptual hash called NeuralHash.[34]

Siri and Search are also being updated to intervene when users perform searches for queries related to CSAM. The Messages app will warn children and their parents when receiving or sending sexually explicit photos, blurring sent and received photos.

Other changes[edit]

  • New widgets have been added: Mail, Contacts, Game Center, Find My, App Store, Sleep.
  • iOS 13 wallpapers were removed in the first beta of iOS 15.
  • iOS 15 features a new wallpaper in two modes: light and dark.
  • SharePlay is removed and disabled in iOS 15. SharePlay is not working yet in iOS 15, but will be re-enabled in iOS 15.1.
  • The 'Other' storage has been renamed to 'System Data'
