Localize your app listing for iOS and Android

Most apps live or die by how well they speak to their users. That includes the language of the store listing, not just the app itself. A localized title and description tell potential users that the product is built for them. It also unlocks search terms in other languages that your competitors might ignore.

Start with the markets where you already have traction. Look at your App Store Connect and Google Play Console data. Where are your installs coming from? Which regions have high impression counts but low conversion? Those are your first localization targets. Do not translate into twenty languages on day one. Pick two or three markets, do them well, and measure the result.

Each store has different fields to localize. On the App Store, you localize the app name, subtitle, description, keywords, screenshots, and preview video. On Google Play, you localize the title, short description, full description, screenshots, feature graphic, and video. The keyword field only exists on the App Store, so Google Play descriptions need to carry more of the keyword load.

Translation quality matters. Machine translation is good enough for a first draft, but it misses cultural context. A phrase that sounds direct in English can feel rude in Japanese. A joke that works in Spanish might fall flat in German. Have a native speaker review the final copy, even if it is just a friend or a community member. Better metadata leads to better conversion, so this is worth the effort.

Screenshots should be localized too. Text in screenshots is often the most readable part of the listing, especially on mobile. Replace every label, button, and headline with the translated version. If your app supports right-to-left languages, make sure the screenshot layout reflects that. Even a screenshot of a calendar should use the local date format.

Store requirements vary by language. Some languages need more characters to say the same thing, which can push you over the App Store title limit. Some languages use compound words that do not split well. Test your localized metadata in AsoFast or directly in App Store Connect and Google Play Console before publishing. Character count checks are easy to forget and painful to fix at the last minute.

AsoFast helps by keeping all your locales in one place. You can generate first drafts for each language, compare them side by side, and export the full set when you are ready. The character counters update as you type, so you catch overflow before it reaches the store. Because the tool runs locally, you can also store draft translations for unreleased features without exposing them.

Measure the impact of each locale after launch. Look at conversion rate by country, organic search impressions, and keyword rankings. A successful localization often shows up first as a higher page view to install rate, not just more downloads. If conversion improves but impressions stay flat, you may need stronger keywords in that language. If impressions rise but conversion drops, your screenshots or description may not feel native enough. Be patient, because organic search can take a few weeks to reflect new metadata.

Localization is not a one-time project. Markets change, competitors enter, and your app gains new features. Set a reminder to review your top three locales every quarter. Small updates to a title or description can reopen search traffic in a region where growth had stalled.

If you are serious about growing outside your home market, treat localization as product work, not an afterthought. The developers who win globally are the ones who make users feel like the app was built in their language from the start.
