FAQ

What are the App Store character limits?

Apple App Store limits: app name 30 characters, subtitle 30, keywords field 100, promotional text 170, description 4,000, and What's New (release notes) 4,000.

What are the Google Play character limits?

Google Play limits: app title 30 characters, short description 80, and full description 4,000 characters.

How does the App Store keywords field work?

You get 100 characters total, separated by commas with no spaces between terms. Don't repeat words already used in your app name or subtitle - Apple indexes those separately, so repeating wastes characters.

Do emojis count as one character?

This counter measures by Unicode code points, so most emoji and accented letters count as a single character - matching how the stores measure your fields. Note that some emoji and the App Store keyword field have additional rules.

Is my text saved or sent anywhere?

No. The counter runs entirely in your browser. Nothing you type is stored, uploaded, or sent to any server.

Next step in AppGrowthKit

Metadata within limits - screenshots still sell the install

Title, subtitle, and description get you indexed. Screenshots decide whether someone taps Install. After you stay inside App Store and Google Play character limits, pair that copy with a visual story that matches your keywords.

AppGrowthKit turns listing copy into a full screenshot set: frames, headlines, backgrounds, and store-ready export - so your ASO research becomes a listing that converts.
