 # AIS-catcher for Android - A multi-platform AIS receiver 
 This Android App helps to change your Android device into a dual channel AIS receiver that can be used to pick up AIS signals from nearby vessels, even if offline!
-The App directly accesses a Software Defined Radio USB device and can send received messages via UDP to plotting Apps like [Boat Beacon](https://pocketmariner.com/mobile-apps/boatbeacon/) or [OpenCPN](https://play.google.com/store/apps/details?id=org.opencpn.opencpn_free). A lightweight AIS receiver system when travelling. AIS-catcher for Android has been tested on an Odroid running Android.

 Below you can find a link to the APK file or visit the [Google Play Store](https://play.google.com/store/apps/details?id=com.jvdegithub.aiscatcher&gl=NL). The engine and visualizations are based on [AIS-catcher](https://github.com/jvde-github/AIS-catcher). 
 
 AIS-catcher had a recent overhaul. The instructions below still are relevant but the visualization of the results is now based on the same code as the AIS-catcher web interface. The instructions will be updated in due course.
