App Store Metadata Checker
Draft your metadata here and watch the counts: app name, subtitle, keywords, promotional text, and description, each with its App Store Connect limit built in. Runs in your browser – nothing is uploaded.
Limits are per localization – every language gets its own 30, 100, and 4,000 characters. Nothing you type leaves your browser.
Frequently asked questions
What are the App Store character limits?
You get 30 characters for your app name and subtitle, 100 for your keywords, 170 for promotional text, and 4000 each for description and what's new. Each of these are provided per localization in App Store Connect.
Which fields affect search ranking?
Your app name, subtitle, and keyword field are indexed for search, so make every character in those three count. The description and promotional text sell the download once someone arrives; run your keyword field through the App Store Keyword Optimizer for deeper checks.
Does promotional text need an app review?
No, promotional text can be updated any time without submitting a new version, which makes it ideal for announcements and seasonal messages.
