The App Store app name limit
An App Store app name can be up to 30 characters. Apple indexes the name for App Store search, and it shows on the product page, in search results and under the icon (where a long name is cut to fit).
How to write a App Store app name
Keep the brand short and memorable, and use the remaining characters for the one keyword people search for. Apple rejects names that use another app's or company's trademark, price terms like "free", or keyword stuffing.
Questions
What is the App Store app name character limit?
30 characters. App Store Connect refuses a longer name.
Does the app name affect App Store search?
Yes. The name, subtitle and keyword field are the text Apple indexes for search, and the name carries the most weight.
Can the App Store name differ from the name on the home screen?
Yes. The home screen shows the bundle display name, which can be shorter than the App Store name.
Do spaces and emoji count?
Spaces and punctuation count as one character each. This checker counts each visible character once, so an emoji counts as one.
Is my text stored or sent anywhere?
No. The counting happens in your browser and nothing is uploaded.
