Promotional text allows 170 characters. You can change it without an app update.
170max
Promotional text length: what the 170 characters are for
Shoppers see promotional text above the description. Apple does not index it for search. Keyword stuffing here does not help you get found.
You can update it in App Store Connect without uploading a new build. The subtitle cannot do that.
Write one current reason to install or update: a feature that just shipped, a season, or a single benefit. Then stop.
Examples that fit
-
“New: speaker labels on every transcript. See who said what, then share the notes.” (81)
One new feature. Not a keyword list.
-
“This week’s meal plan is ready. Swap a dinner, keep the grocery list in sync.” (77)
Timely, and still about the product.
-
“Offline maps now include trail closures. Download a region before you lose signal.” (82)
A concrete update a hiker can use.
What to do next
When the length passes, check the live listing or draft the field with Nakxi. Neither step changes your rank by itself.
FAQ
What is the App Store promotional text character limit?
170 characters, including spaces. Promotional text length and the 170-character limit are the same cap.
Can I update promotional text without an app update?
Yes. You can change it in App Store Connect without uploading a new build. The subtitle and description wait for a version release.
Is promotional text indexed for search?
No. Apple does not use it as a keyword field. Shoppers see it above the description, so write it for people, not for a keyword list.
What should promotional text say?
A current reason to look: a new feature, a seasonal use, or one concrete benefit. It is not a second subtitle. Keep the indexed keywords in the name, subtitle, and keywords field.
