What is the promotional text limit?
170 characters. App Store Connect Help says it can't be longer than 170 characters, and the product page guide says it appears at the top of the description.
Can you change promotional text without an update?
Yes. It's the only text field you can update at any time without submitting a new version. The name, subtitle, keywords and description all wait for one.
What should you use promotional text for?
Apple suggests the latest news about your app, such as limited-time sales or upcoming features. It also suggests putting an accolade here or at the end of your description.
Because it changes without review, it's the line to rewrite on launch day, for a sale, or when a new feature ships.
Does promotional text help App Store search?
No. Apple says promotional text doesn't affect your app's search ranking, so it shouldn't be used to show keywords. Write it for the people reading it.
