# Use the SDK with Marketing Cloud Engagement

The Salesforce Engagement SDK, formerly called the MobilePush SDK, helps you integrate push notifications, in-app messages, and location-based messaging into your mobile apps. Use the SDK to engage users, track analytics, and deliver personalized experiences.

## Get Started

Begin by integrating the SDK into your mobile apps:

- [Integrate the SDK for Android](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_integrate_android/engagement_sdk_guide_integrate_android.md)
- [Integrate the SDK for iOS](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_integrate_ios/mc_engagement_integrate_ios.md)
- [Integrate the iOS Extension SDK](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_integrate_ios_extension/mc_engagement_integrate_ios_extension.md) to add support for rich notifications and delivery tracking on iOS.

If you use Cordova, React Native, or Flutter to develop your app, you can also [integrate the SDK with those platforms](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_development_frameworks/mc_engagement_development_frameworks.md).

## Implement Core Features

After you integrate the SDK, implement its core features based on the needs of your app:

- [Register Contacts and Devices](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_register_contacts_devices/mc_engagement_register_contacts_devices.md) — Associate devices with contacts and manage contact attributes and tags.
- [Push Notifications](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_push_notifications/mc_engagement_push_notifications.md) — Send push notifications to users of your app.
- [In-App Messages](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_in-app_messages/mc_engagement_in-app_messages.md) — Display messages within your app.
- [Inbox Messages](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_inbox_messages/mc_engagement_inbox_messages.md) — Create a message inbox in your app.
- [Location Messages](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_location_messages/mc_engagement_location_messages.md) — Send location-based messages using geofences and beacons.
- [Analytics](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_analytics/mc_engagement_analytics.md) — Track user interactions and integrate with product recommendations.
- [Event Tracking](https://developer.salesforce.com/docs/marketing/mobile-unified-sdk/guide/mc_engagement_event_tracking/mc_engagement_event_tracking.md) — Track custom events in your app.
