Apple allows up to 4,000 characters for an app description. You do not need to use them all. Start with the user problem and the result your app supports, then explain the workflow in short sections.
Name features people can use today and say who the app is for. If a feature needs an account, subscription, or permission, make that clear. Avoid invented numbers, vague superlatives, and repeated keywords.
A useful structure is: one-sentence promise, three benefits, how it works, who it is for, and a call to action. Make sure screenshots support each claim and adapt the wording for each market.
Use this in your next ASO review
Turn the advice above into one small, traceable change. A simple review keeps your listing accurate and makes it easier to learn what helped.
- Open the current App Store Connect entry for your app and copy the app store description material you want to check.
- Compare it with the current product behavior, supported locales, and the source linked below.
- Draft one improvement, record the reason, and validate every field limit or submission rule that applies.
- Ask a person to approve the draft before it changes a live listing.
