Name and subtitle checker
Check the 30-character App Store app name and subtitle limits side by side.
Localization counter
Track metadata limits across app name, subtitle, keywords, promotional text, and descriptions.
Screenshot sizes
Reference common iPhone and iPad screenshot dimensions before exporting images.
Preview generator
Build a simple App Store copy preview from title, subtitle, promotional text, and keywords.
ASO checklist
Walk through the minimum metadata, screenshot, localization, and measurement steps.
