First Developer Beta of watchOS 26.3 Now Available for Download on Apple Watch
I’m sure you’re not even done enjoying watchOS 26.2 on your Apple Watch, and Apple has already one-upped everyone with the release of watchOS 26.3 developer beta 1.
If you are feeling adventurous and wish to take watchOS 26.3 beta for a spin, you can do that right now. Just launch the Watch app on your iPhone and then go to General > Software Update > Beta Update. Enable watchOS 26 Developer Beta from this section.
Once you do this, you have set your Apple Watch up to receive developer beta updates. This means if you go to Watch > General > Software Update, you’ll immediately see the new watchOS 26.3 beta update. Whether you want to install it immediately or let it be is entirely up to you.
At the time of writing, little is known about the new update, and if there’s anything worth talking about, I’ll cover it in a separate blog post.
