When choosing a name for your own app, make sure it follows the naming guidelines for both Apple's App Store and Google Play.
Name guidelines
Your app name can not include:
Any special characters (e.g. #,@,&) or emojis
Prices or pricing information (e.g. 'Free app!')
Trademarked names or data
Names already used in popular apps or references to other apps
Inappropriate or irrelevant content
Names over the 30 character limit
Tips for submission
Read the tips below for choosing a name that won't be rejected:
Pick a unique name that accurately describes your app and its content.
Choose a name that is simple and easy for your users to remember.
Don't try to 'game the system' as Apple says by using popular or existing app names to draw more attention to your app.
Reflect the app's core features in the name
Check the availability of the name before you submit. This includes all social media handles and domain names as well.
Tip:
Use the subtitle in the Store Listings section of your app's dashboard to provide extra context about your app without including it in the name.
