Enables new ways to personalize your iPhone with deeper customization of the Home screen and Control Center; the biggest redesign ever in Photos, making it even easier to find and relive special moments; and major improvements to Messages and Mail.

Starting next month, iOS 18 will introduce Apple Intelligence, the personal intelligence system that combines the power of generative models with personal context to deliver incredibly useful and relevant intelligence while protecting users' privacy and security, Apple said in a statement.

"In iOS 18, users can personalize their home screen in interesting new ways by placing app icons and widgets to frame the wallpaper or create the ideal layout on each page," the company reported.

Users can also choose how app icons and widgets are presented (light, dark, or with a color tint) or make app icons appear larger for a new, streamlined look.

They can also access their favorite controls from the Action button, and for the first time, they can change the controls on the lock screen or remove them entirely.

“The expanded Photos update makes it easier to find and relive special moments. The beautiful, simplified layout gives the library a unified yet familiar view. New collections like Recent Days, People & Pets, and Travel automatically keep your library intelligently organized on your device,” according to the company.

In Messages, formatting options like bold, italic, underline, and strikethrough allow users to better convey tone; New text effects bring words, phrases and sentences to life; Emoji Tapbacks and Stickers give users endless ways to react in a conversation; and users can compose an iMessage to send later.

For times when cellular and Wi-Fi connections are not available, Satellite Messages connects users to a satellite in space directly from the Messages app to send and receive text messages, emoji, and Tapbacks via iMessage and SMS .

The Phone app helps users stay organized with the ability to record and transcribe live calls, making it easier to remember important details later.

Available later this year, categorization in Mail organizes messages to help users stay on top of their inbox.

iOS 18 is a free software update available today for iPhone Xs and later.
