Is it possible to include emoji in the app description in the App Store? Wouldn't the app be rejected or banned?
Thanks for your question, Anastasia. Using emoji is not against the guidelines of Apple. Here you will find several tips you should be aware of: https://splitmetrics.com/blog/apple-app-store-guidelines/

Here you find an example in practical terms: https://stackoverflow.com/questions/9891204/additional-icon-in-app-name-lable

However, I think emojis should be used carefully, depending on what target group you want to reach and what you want to achieve...
