iOS 18 vs. iOS 18.1: Here's How the Two Updates CompareAs a result of the first Apple Intelligence features being delayed, iOS 18 and iOS 18.1 are currently in beta testing simultaneously.
Below, we explain the differences between the two upcoming software updates, including new features and estimated release timing.
<h2>New Features</h2>
<h3>iOS 18.0</h3>
iOS 18 introduces new customization options for the Home Screen and Control Center, a redesigned Photos app, numerous enhancements to the Messages app, an option to lock apps behind Face ID or Touch ID, and much more.
The highlight of iOS 18 is Apple Intelligence, but the rollout of these artificial intelligence features was pushed back to iOS 18.1.

iOS 18 roundup to learn more about the update.
<h3>iOS 18.1</h3>
The first iOS 18.1 developer beta added
some Apple Intelligence features for testing, including new writing tools for generating and summarizing text, suggested replies in the Messages app, email summarization, phone call recording and transcribing, and a few others.
The third iOS 18.1 developer beta added a few more Apple Intelligence features, including a
"Clean Up" tool in the Photos app that "can identify and remove distracting objects in the background of a photo," and
notification summaries for additional apps beyond Mail and Messages.
Apple Intelligence features that are
still not available to try include Image Playground for custom-generated images, Genmoji for custom-generated emoji, and several enhancements to Siri, including ChatGPT integration, richer language understanding, deeper per-app controls, on-screen awareness, and personalized context.
<h2>Release Timing</h2>

<li>iOS 16: September 12, 2022</li>
<li>iOS 15: September 20, 2021</li>
<li>iOS 14: September 16, 2020</li></ul>
<h3>iOS 18.1</h3>
iOS 18.1 will likely be released in late October, based on the timing of previous similar updates:
<ul><li>iOS 17.1: October 25, 2023</li>
<li>iOS 16.1: October 24, 2022</li>
<li>iOS 15.1: October 25, 2021</li>
<li>iOS 14.1: October 20, 2020</li></ul>
<h2>Latest Versions</h2>
As of August 28 at 12:55 p.m. Pacific Time, the latest iOS 18 and iOS 18.1 betas are as follows:
<ul><li>
iOS 18 Developer Beta 8</li>
<li>iOS 18 Public Beta 5</li>
<li>
iOS 18.1 Developer Beta 3</li>
<li>iOS 18.1 Public Beta not currently available</li></ul>
<h2>How to Install Betas</h2>
<h3>Developer Betas</h3>
iOS 18 and iOS 18.1 are both available as developer betas.
To enroll in Apple's developer beta program, visit
developer.apple.com, sign in to your Apple ID, and accept the terms and conditions of the Apple Developer Agreement.
Since 2023, installing iOS developer betas no longer requires being enrolled in the Apple Developer Program for $99/year. Anyone with an Apple ID can accept the Apple Developer Agreement and access the betas for free.
After accepting the agreement, open the Settings app on your iPhone and tap General → Software Update → Beta Updates. This is where the iOS 18 and iOS 18.1 developer betas are listed, and you can tap on one to begin the installation process. Note that the iPhone must be signed in to the same Apple ID set up as a developer account.
Due to software bugs and other potential issues, we recommend installing the iOS 18 or iOS 18.1 betas on a secondary iPhone, rather than the device that you use daily. We also highly recommend
backing up your iPhone to your Mac before installing beta software on the device, to prevent data loss in the event something goes wrong.
