Anyone interested can download the iOS 27 developer beta for free — right now.
You’ll be among the first to try the exciting new Siri AI, which really does work as promised. It can answer complex questions about your digital life, understand what you’re asking for and look things up online with broad world knowledge. You’ll also get the other new Apple Intelligence features, a tweaked Liquid Glass design, improved speed and performance, and much more.
Of course, there are a few things you should look out for. Beta software is buggy and can lead to data loss. That being said, iOS 26 has been buggy since September. iOS 27 promises broader system stability — unlike most early betas, in my testing, the system runs smoother than before. But it comes at the expense of odd behavior you may find in third-party apps, since they haven’t been updated to support the new changes to Liquid Glass.
If you want to try it out, you should make sure you have a backup of your most important data with two copies of your photo library before you try installing. I’ll show you how.
