Make the subject large
Small sticker details disappear quickly in iMessage. Keep the main character large, center the expression, and use enough white space around the silhouette.
Create repeated daily replies
Useful iPhone packs include hello, good night, love this, wait what, no, yes, thanks, crying, excited, and thinking. These replies match everyday chat behavior.
Use the app for saving the final pack
A web page can help users discover and preview stickers, but the app should handle the final save or export path so the user can keep the pack.
