App Localization Â鶹APP
Win users in every store, in every language. We localize mobile apps end to end — the in-app interface, the app store listing, and the on-device experience — for iOS, Android, and cross-platform, in more than 200 languages, so your app feels native wherever it is downloaded.

App localization has two jobs: get your app discovered in each market, and make it feel native once it is installed. Both matter, and both are easy to get wrong — a store listing that ignores local search terms never gets downloaded, and an interface with truncated buttons or untranslated alerts gets uninstalled. We handle the full picture, from the App Store and Google Play listing to the last in-app string, as a focused part of our broader localization services and a close companion to our software localization work.
What we localize
We cover everything a user sees before and after install, matched to linguists who know mobile:
- In-app UI strings — screens, menus, buttons, and alerts.
- App store listings — titles, descriptions, keywords, and what’s-new notes.
- Onboarding and notifications — first-run flows and push messages.
- In-app purchases and paywalls — pricing screens and subscription copy.
- Help and support — in-app help, FAQs, and support content.
- Screenshots and store creative — the captions that sell the app.
App store optimization (ASO)
Discovery starts in the store, so we localize for it deliberately. We research the keywords users actually search in each App Store and Google Play locale and build the localized title, subtitle, description, and keyword field around them, rather than translating your English listing word for word. We localize the text on your screenshots and the what’s-new notes too, because a listing that reads native and ranks for local terms is the difference between an app that is found and one that is buried. Good ASO turns localization from a cost into a growth channel.
Engineering for iOS and Android
Each platform has its own localization mechanics, and we handle both natively. On iOS we work with .strings and .stringsdict files and Xcode localization; on Android, with strings.xml resource files and the resource-qualifier system. We manage plurals correctly for every language, respect placeholders and format specifiers so nothing crashes, plan for text expansion that strains a phone’s small screen, and support right-to-left layouts. Where useful we pseudolocalize first to catch hard-coded strings and layout problems before translation begins.
Continuous localization for frequent releases
Apps update constantly, so our workflow keeps up. Translation memory reuses strings across versions for consistency and lower cost, and we connect to your repository and build tools — including fastlane and CI pipelines — so new and changed strings flow to us and back automatically. That continuous approach means a new feature or a fresh store listing can ship localized on the same cadence as the English release, not weeks behind it.
On-device QA
An app is localized only when it looks and works right on a real screen. We run localization QA on devices and simulators across iOS and Android, checking each language for truncation, overlapping controls, broken layouts, encoding issues, and functional bugs, and we verify the store listing renders correctly. You get an app that has been seen in each language on the kind of device your users actually hold, not just a translated string file.
We localize apps across categories — consumer, gaming-adjacent, productivity, fintech, health, and enterprise — for indie developers shipping their first international release and publishers managing dozens of locales at once. Because most app growth now comes from outside the home market, localization is rarely a one-time task: we help you decide which markets to enter first based on where your downloads and revenue potential are, then expand language by language as the data comes in, so spend follows opportunity rather than guesswork.
Languages and locales we cover
We localize apps into more than 200 languages and locales, with care for the store-specific and regional variants that matter — Latin American versus European Spanish, Simplified versus Traditional Chinese. The most requested include Spanish, French, German, Japanese, Korean, Chinese, Portuguese, Italian, and Arabic, with additional locales sourced on request.
Why companies choose us
We are a family-run, women-owned (WBENC) firm, registered in SAM.gov, with more than two decades of experience and most of our linguists on board for over ten years. We deliver in-house rather than brokering, pair linguists with localization engineers, and treat the store listing and the in-app experience as one job. App localization pairs naturally with our software and game localization. Talk with our CEO: to plan your app localization.
Frequently asked questions
Do you localize the app store listing as well as the app?
Yes. We localize the in-app interface and the App Store and Google Play listing — title, description, keywords, screenshots, and what’s-new notes — with ASO in mind.
Which file formats and platforms do you support?
iOS (.strings, .stringsdict, Xcode) and Android (strings.xml and resource qualifiers), plus cross-platform frameworks, handling plurals, placeholders, and right-to-left layouts.
Can you fit our release pipeline?
Yes. With translation memory and connectors to your repo and tools like fastlane and CI, changed strings flow automatically for continuous localization.
Do you test on real devices?
Yes. We run localization QA on devices and simulators across iOS and Android, checking truncation, layout, encoding, and functionality in each language.
Which languages do you cover?
More than 200 languages and locales, including regional variants, with the most common being Spanish, French, German, Japanese, Korean, and Chinese.
