The demo applications and code samples can help you quickly get started with OHS
components:

- *Structured Data Capture Catalog App* : In this demo app you can see and
  interact with components and layouts that are supported by the Structured
  Data Capture library. [Build and run instructions](https://github.com/ohs-foundation/android-fhir/wiki/SDCL%3A-Structured-Data-Capture-Catalog)

- *FHIR Engine Demo App* : This demo application showcases many of the core
  capabilities of the FHIR Engine Library. The Demo app uses the public HAPI
  FHIR demo server as the server to sync with and all data is visible to
  anyone on the internet. [Build and run instructions](https://github.com/ohs-foundation/android-fhir/wiki/FEL%3A-Demo-app)

- *OHS based FHIR app example repository* : This example repository contains
  code samples and instructions for using the OHS components together. It
  includes a demo Android app that uses the Android FHIR SDK to show a patient
  registration questionnaire and save responses locally. It also syncs data
  with a FHIR server through the FHIR Info Gateway, which provides access
  control to FHIR resources based on the authenticated user. Finally, FHIR
  Data Pipes periodically transform the data to Parquet files that you can
  query to perform analytics.
