Mobile App Localization
Localize your mobile applications quickly and at scale with Phrase
Phrase is trusted by 3,600+ localization teams worldwide

Looking to localize your mobile app? Phrase makes it simple.
Mobile app localization can be time-consuming and error-prone. Manual imports and exports, design breaks, and out-of-context translations delay releases and create a bad user experience.
The Phrase platform can help you scale efficiently with seamless translation workflows for developers and native-quality user experiences.
How does Phrase make mobile app localization effortless?
Publish updates instantly with over-the-air localization
Deliver the most up-to-date copy to your users without waiting for app store approvals. Phrase’s over-the-air (OTA) technology lets you localize apps and push mobile app translation updates instantly across iOS, Android, React Native, and Flutter. No new app version required. No app restart needed.

Keep app copy consistent with linked keys
Avoid duplicate edits and translation errors across mobile platforms. With linked
keys, you can update a single string and apply changes automatically across all connected iOS and Android projects, making application localization smoother,
faster, and more reliable.

Automate localization with Phrase’s developer-friendly API
Free up engineering time and reduce release delays. Use our robust API to
automate mobile localization workflows, trigger updates with webhooks,
and fully integrate Phrase into your CI/CD pipeline. Continuous localization
happens behind the scenes, so your team can stay focused on building.

Gain insight with OTA analytics
Understand how users interact with localized versions of your app. With Phrase’s
OTA SDK, you get detailed analytics on distribution usage, top-performing
languages, and even unmet language demand, helping you prioritize mobile
app localization efforts.

Improve translation quality with in-context previews
Say goodbye to out-of-context copy. Phrase’s integration with Figma enables translators to see strings in their visual design environment, helping them write translations that are accurate, natural, and layout-friendly.

FREQUENTLY ASKED QUESTIONS
Your questions answered on our strings translation editor
What platforms do you support?
Phrase over-the-air currently supports delivering translations to iOS, Android, React Native and Flutter. See more details in our documentation.
Is there a limit for the amount of releases I can create?
No, the only limit regarding OTA is the amount of MAU (monthly active users), depending on which pricing plans you have chosen.
What constitutes a monthly active user (MAU)?
When a user starts an application implementing our iOS, Android, React Native, or Flutter SDK for the first time on a device, we generate a unique, random device Identifier. This identifier’s sole purpose is the tracking of active users over a given period of time. It is not used for any other form or means of tracking and does not contain any user or device information. Also, we will not automatically lock your organization or OTA functionality when you exceed your MAU quota, but instead reach out to explore options going forward.
How does OTA (Over-the-Air) localization work in Phrase?
Over-the-air (OTA) localization lets you update your app’s copy and translations without waiting for a full app store release. With Phrase Strings, you can push new or updated translations instantly to mobile apps on iOS, Android, Flutter, and React Native even while users are actively using the app. OTA works seamlessly with your existing development pipeline, reducing release cycles and improving user experience across languages.
Can I use Phrase for mobile app localization without involving developers?
Yes. While Phrase Strings is developer-friendly, it’s also built for collaboration with non-technical stakeholders. Product managers, localization teams, and translators can manage content directly through the web interface, using tools like the in-context editor, style guides, and glossary management. Developers can configure workflows once using CLI, API, or integrations with Bitbucket, GitHub, or GitLab, then hand off day-to-day localization tasks without ongoing coding effort.
