Look for pack creation, not just cutouts
Many apps can cut out a photo, but a stronger sticker maker helps you create a full set of emotions with the same character. That is what makes the result useful in iMessage and other social apps.
Check export and saving workflows
A good iPhone workflow should make it obvious how to save the pack, open it later, and use the stickers in chats without hunting through files or camera roll exports.
Prioritize clarity at small sizes
Sticker previews should show whether the face, caption, and outline still read in a chat bubble. If a sticker only looks good full screen, it will feel weak in daily use.
