Character Limits
Character limits define the maximum text length for each metadata field in the app stores. Exceeding limits causes submission rejection; optimal usage maximizes keyword coverage.
Character limits vary by platform and field. Key limits: App Name (30), Subtitle (30, Apple only), Keywords (100, Apple only), Description (4000), Promotional Text (170, Apple only), Google Play Short Description (80).
Maximizing character usage is essential for keyword coverage. Every unused character in your keyword field or title is a missed opportunity for search visibility. Use all available space strategically.
