ASO Check: Assess App’s ASO Performance Across Locales

For memberships with access to the ASO analysis: Indie and Pro

The ASO Check feature provides an evaluation of selected app’s ASO performance across all 39 locales available in the App Store.
It displays how well app’s metadata (titles and subtitles) covers each localization, helping you assess the app’s visibility and optimization on a global scale.

The ASO Check feature is accessible through the App Info screen and from side menu.

Simply select the app you want to analyze.

ASO Check analyzes the app’s metadata, including title and subtitle, for each of the 39 App Store localizations.
It compares them with unique titles and subtitles already present in the App Store to determine how well the app is optimized for each locale.

Next to the main app information, you’ll see a summary of metadata uniqueness:

  • The card labeled All shows the total number of unique titles and subtitles across all 39 localizations.
    (In the screenshot, 31 / 39 unique titles)
  • The card labeled US: United States shows the number of unique titles and subtitles for evaluating the completeness of US cross-localizations (unique out of 10 cross-localizations).
    (In the screenshot, 8 / 10 unique titles)

Then, cards are displayed for each App Store locale.
Each card shows:

  • the locale name
  • the title and subtitle for each locale
  • the app’s rating and number of ratings for that locale
  • an indicator of the uniqueness of the app’s videos and images

This allows you to quickly identify areas where the selected app’s metadata needs improvement.

Card Color Coding

Cards are colored differently depending on the state of the app’s metadata:

  • Light-gray-filled cards indicate that the app’s metadata is not optimized for the selected locale.
  • Red-filled cards indicate that the app’s metadata is unavailable for the selected locale.

Localized Media Files

Unique elements are marked in blue (determined by the image or video link without detailed frame analysis), while duplicates are marked in gray.
Hovering over them shows in which localizations the same screenshots and videos are used.
