ASO character counter

Write every App Store and Google Play metadata field against its exact character limit. Live counts, over-limit warnings, and the rules for each field — so nothing gets truncated at submission.

Your app's title. The single biggest keyword field — make it count.
Subtitle0 / 30
One line under the name. Indexed for search — add keywords, not a tagline.
Keywords0 / 100
Comma-separated, no spaces. Don't repeat words already in the name or subtitle.
Promotional Text0 / 170
Shown above the description. Not indexed, but updatable without a new build.
Description0 / 4000
Full description. Not indexed for keywords on the App Store — write for conversion.
What's New0 / 4000
Release notes shown with each update.

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.
