Frequently Asked Questions
App Store Metadata Character Limits
Every metadata field on the App Store and Google Play has a strict character limit. Exceeding these limits will cause your submission to fail, while underusing them means you are leaving keyword opportunities on the table. Knowing the exact limits for each field — and optimizing to use every available character — is one of the simplest ways to improve your app's search visibility.

On the Apple App Store, your app name is limited to 30 characters. Your subtitle also gets 30 characters. The keyword field allows exactly 100 characters — this is the most constrained and most valuable field for ASO, since every character counts toward search indexing. Your description can be up to 4,000 characters, though Apple does not index descriptions for search. Promotional text gets 170 characters and can be updated without submitting a new build. Release notes allow up to 4,000 characters.
On Google Play, the title limit is 30 characters (reduced from 50 in 2021). The short description allows 80 characters and appears above the fold on your listing — this field is directly indexed for search and should be treated as prime keyword real estate. The full description allows 4,000 characters and is also indexed, so keyword placement throughout the text matters. Release notes are limited to 500 characters.
The most common mistakes developers make are repeating title words in the iOS keyword field (which wastes characters since Apple indexes them separately), leaving the short description on Google Play generic instead of keyword-rich, and writing descriptions that are too short to cover their full keyword set.
