FaceTime Upgrades

iOS 15 introduced major improvements to FaceTime to make video calls more natural and collaborative:

Focus Modes and Notification Summary

To minimize distractions, iOS 15 added Focus, a tool that filters notifications and home screen pages based on what the user is currently doing, such as working, sleeping, or exercising. Additionally, notifications received a visual refresh with larger app icons and contact photos, alongside a scheduled Notification Summary that bundles non-urgent alerts for delivery at designated times throughout the day.

Live Text and Visual Look Up

With on-device intelligence, iOS 15 introduced Live Text, which recognizes text within photos, screenshots, and the live Camera feed. Users can copy text, translate languages, look up addresses, or dial phone numbers directly from an image. Visual Look Up allows users to identify objects such as plants, pets, landmarks, and works of art captured in their photo library.

Redesigned Safari

The Safari web browser was redesigned with a compact tab bar located at the bottom of the screen for easier one-handed navigation. It also introduced Tab Groups, allowing users to organize and save collections of tabs that sync across Apple devices, along with support for third-party web extensions.
