About this app

An Android utility that forces a specific locale on individual apps — even apps that have no in-app language setting and never show up under Settings → Apps → App language.

Your phone can stay in Japanese while WeChat and Taobao run in 简体中文, ChatGPT runs in English, and Google Maps stays Japanese.

This is not a translator. It changes the locale an app sees. If the app does not ship resources for that language, nothing visible will change. See What this cannot do.

What it actually does Android 13 introduced per-app locales. The system keeps a per-package LocaleList override and applies it to that app's Configuration when the app starts. Apps do not have to opt in for this to work — the framework overrides the configuration regardless.

What apps do have to opt in to is being listed: Settings → Apps → App language only shows apps that ship a locales_config.xml (android:localeConfig). Apps without it are invisible in Settings even though the underlying override works perfectly.

This app writes that same override directly, for any installed package.
