App localization varies between Google Play and the App Store in metadata, translation support, review processes, and keyword strategies, impacting ASO and global reach in UK.
App localization plays a crucial role in reaching global audiences by adapting apps to different languages, cultures, and regions. While both Google Play and the App Store support localization to enhance visibility and user engagement, their approaches vary significantly in features, workflows, and technical requirements.
These differences stem from platform-specific priorities: Google Play emphasizes flexibility and speed, whereas the App Store focuses on precision and quality control.
Understanding these variations helps developers optimize strategies for better app store optimization (ASO) and user acquisition.
Google Play allows localization of the app title, short description, and full description in over 70 languages. Keywords are indexed directly from the title and descriptions, without a dedicated field. A standout feature is the support for up to 50 custom store listings, which can be tailored for specific regions or user segments with unique names, icons, and screenshots. This enables targeted marketing without broad changes.
In contrast, the App Store supports localization of the app title, subtitle, keywords, description, promotional text, and screenshots. It includes a dedicated keyword field per locale, allowing unique keyword sets to boost discoverability in different markets. However, there are no custom store listings; all updates must go through App Store Connect and undergo manual review.
These distinctions highlight Google Play's broader customization options compared to the App Store's structured, review-heavy process.
Google Play supports 77 locales and offers both manual and automatic translation for descriptions, though manual methods are preferred for accuracy. Automatic tools like Google Translate integrate seamlessly, but developers should verify quality to avoid impacts on keyword ranking.
The App Store, supporting 40 locales, requires all metadata translations to be manual and uploaded by developers. This ensures higher precision but demands more effort.
Broader locale coverage on Google Play benefits apps targeting diverse markets, while the App Store's manual approach promotes cultural accuracy. As AI translation advances, both platforms may integrate more automated features in the future, potentially bridging this gap and improving efficiency.

Google Play features a faster submission process with staged rollouts, allowing updates to listings without full manual reviews. This speeds up iterations and testing.
The App Store mandates manual reviews for every submission and update, resulting in slower cycles but ensuring consistency.
On Google Play, localizing screenshots and video previews is optional but recommended; videos support both portrait and landscape formats.
The App Store requires screenshots for each device type and language, with up to three video previews per device type that must be manually uploaded and localized.
These processes reflect Google Play's agility versus the App Store's emphasis on device-specific quality.
Google Play pulls keywords from title and description fields, with auto-translation potentially affecting rankings in other languages. In-app language follows the device's set language, falling back to default if unsupported.

The App Store indexes keywords from title, subtitle, and a dedicated field, possibly including primary and secondary localizations for cross-market visibility. In-app language uses the user's preferred order from iOS settings.

Developer tools further differ: Google Play Console integrates translation services, while App Store Connect and Xcode handle in-app localization with import/export options.
In evaluation, Google Play provides more flexibility and speed, ideal for rapid global expansion, whereas the App Store offers finer keyword control but with stricter oversight.
Developers should prioritize ASO tactics per platform—leveraging custom listings on Google Play and targeted keywords on the App Store—to maximize downloads. With growing international app markets, effective localization can increase user acquisition by up to 20-30%, based on industry trends, and future updates may include enhanced AI for better cross-platform harmony.
