Add a Digital Pet to Your iPhone - Lifehacker
So long as you have the latest version of the app and an iPhone 14 Pro or 14 Pro Max, you’ll find the option in the Apollo app in Settings > General > Pixel Pals.
Selig made Pixels Pals an Apollo widget option for iOS 16's customizable Lock Screens.
If your iPhone supports Apple’s latest update, and you have the Apollo app installed, you can see your Pixel Pal whenever you want.
Tap “Apollo,” then swipe over to “Pixel Pal.” You can add either a small or large Pixel Pal widget to your Lock Screen, which means you can have two, three, or four Pixel Pals on screen at once.
When you place a Pixel Pal widget on the Lock Screen, it will be Hugo the cat by default.
