The iOS 9 is an operating system designed and developed especially for iPhone and iPad by Apple from 2015 to 2019. The system was introduced on September 9, 2015, released on September 16, 2015, and was preinstalled on the iPhone 6s, iPhone 6s Plus, iPhone SE, iPad Pro 12.9-inch, iPad Pro 9.7-inch, and iPad mini 4.
iOS 9 incorporated many feature updates to built-in apps. Most notably, Notes received the ability to draw sketches with different tools, image insertion, prominent visual appearance for website links and map locations, and advanced list formatting; an all-new Apple News app aggregates articles from different sources; and Apple Maps received mass transit support, although in a limited number of locations at launch.
Major new system updates include proactivity, where Siri and advanced search are combined to make the operating system more contextually aware of information (such as time and location) and can provide the user with information ahead of time. For searching, proactive intelligence can display instant results in a widget-like format, including weather, sports, news, and more.
iOS 9 also added multiple forms of multitasking to the iPad. In iOS 9.3, Apple added a Night Shift mode that changes the color of the device’s display to a warmer, less “blue light” containing shade, to reduce any negative eye health effects on users’ circadian rhythms.
Additionally, iOS 9 brought new user experience functions, including Quick Actions, and Peek and Pop, based on the touch-sensitive display technology in the iPhone 6s.
Quick Actions are shortcuts on home screen app icons. Users can preview (“Peek”) content without moving away from the current screen before they enter (“Pop”) the previewed content into full view.
This software got the last update (9.3.6) on July 22, 2019, but in the meantime was replaced by a newer version of iOS 10. Today iOS 9 is 8 years old!
