# Bitwarden Mobile Application
The Bitwarden mobile application is written in C# with Xamarin Android, Xamarin iOS, UWP, and Xamarin Forms.
# Build/Run
**Requirements**
- [Visual Studio](https://store.xamarin.com/)
**API endpoint**
By default the app is targeting the production API. If you are running the [Core](https://github.com/bitwarden/core) API locally,
you'll need to switch the app to target your local instance. Open `src/App/Utilities/ApiHttpClient.cs` and `src/App/Utilities/IdentityHttpClient.cs` and set the `BaseAddress` to your local
API endpoints (ex. `new Uri("http://localhost:5000")`). Alternatively, you can also adjust the environment endpoints from the environment settings page on the home screen of the app (log out).
**Run the app**
After restoring the nuget packages, you can now build and run the app.
