Start with one photo
Choose a photo, and petsum finds your pet and separates them from the background. If the cutout needs help, fix it with crop and erase, then preview how it will look before you save.

Keep your pet close
petsum turns a photo you took into a familiar face on Dynamic Island and the Lock Screen. It can also bring back one forgotten moment from your photo library at a time.
A name and a little message
Your pet appears with their name and a message that changes with the time of day. Keep several photos in their own spots and swipe to the one you want to see now.
One moment at a time
Pick a favorite album or a few photos. While the Live Activity is running, one of them shows up when you least expect it. Keep it, skip it for now, or never see it again.
