Visually, iOS 15 doesn't alter the way your phone looks, or at least not in a big way.

The tab bar in Safari can live at the bottom of your screen in iOS 15.

If you want that tab bar back at the top where it's been since 2007, you can tap the AA button and select Show Top Address Bar. For instance, in Safari the tab bar can be moved to the bottom of your phone's screen to make it easier to reach one-handed. Following in the smart footsteps of iOS 13 and 14, iOS 15 lets you decide how much you want to change your iPhone experience. These three updates are like a movie trilogy, but unlike The Lord of the Rings there isn't an ominous Eye of Sauron looming over your every move, just Siri. On the whole, iOS 15 feels like a continuation of iOS 14, which felt like a continuation of iOS 13. I've been testing iOS 15's new features, and everything from bigger additions like FaceTime call web links for friends on Android and Windows to smaller changes like pinning conversations to the top of the Messages app has improved my iPhone - without disrupting my day. The new operating system was in public beta for months undergoing a variety of tweaks leading to its final release. Whether you're getting Apple's new iPhone 13 or holding onto a 6-year-old iPhone 6S, iOS 15 is now available for download.
