San Francisco, Sep 21 : Tech giant Apple is now rolling out iOS 15, iPadOS 15, watchOS 8 and tvOS 15 to iPhone, iPad, Apple Watch and Apple TV devices.

Users might not see the updates right away, but when they are available, they will have access to a bunch more features, reports Engadget.

Facetime and Messages have been upgraded on both iPhone and iPad. Facetime supports spatial audio and reduces background noise, while people can join Facetime calls through shareable links on the web and Android.

It will be easier to keep track of things your friends and family share with you in Messages thanks to dedicated tabs in the News, Music, TV and Podcasts apps, the report said.

Notifications have also been overhauled. Users will have more control over push alerts and they can let only notifications from select apps and people through when they activate one of the new Focus modes.

On iPad, Quick Notes are now a system-wide feature -- just swipe in from the lower right corner to jot down some thoughts using the keyboard or Apple Pencil, the report said.

One thing that iOS 15 and iPadOS 15 don't have at launch is the SharePlay feature. It lets you enjoy movies, shows and music together with friends over Facetime and you can share your screen with them.

Apple also put the child safety features it planned to release as part of iOS 15 on the back burner while it makes improvements.

The watchOS 8 update perhaps isn't quite as extensive. There's a bigger focus on mindfulness and health, including some new workout categories.

Apple Watch now has deeper integration with iPhone, with features including Focus mode support and a Contacts app. You can also expect portrait watch faces and multiple timers.

If you have an iPhone 6s or later, iPhone SE (either generation) or seventh-gen iPod touch, you'll be able to install iOS 15.

Those with Apple tablets can run iPadOS 15 on fifth-gen and later iPads, iPad mini 4 and later, iPad Air 2 and later on all iPad Pro devices. Meanwhile, watchOS 8 is supported by Apple Watch Series 3 and later devices.
