Design for the chat bubble scale
A sticker that looks good in a large preview can become noisy in a chat thread. Keep the main subject large, avoid crowded text, and make sure the outline separates from both light and dark backgrounds.
Create reactions people can repeat
Useful iPhone sticker packs cover everyday responses such as hello, love this, no, wow, excited, good night, thinking, and laughing. The more reusable the emotion, the more often the pack gets opened.
Use web pages for discovery
A web preview can help users find a sticker pack from search, then the app can handle saving, exporting, and using the pack on iPhone.
