# Build an in-app integration

> Accept payments natively inside your iOS or Android app using VINR's mobile SDKs and UI components.

VINR's in-app integration lets you collect payments directly inside your mobile app — no webview redirect required. Use prebuilt UI sheets, individual payment Elements, or the full Payment Element to build a checkout experience that feels native on both iOS and Android.
