"VIDEGRO's Ships" is a free Android application which allows you to receive AIS information directly from ships in your neighbourhood using a cheap (10-15 euro) DVB-T-DAB-FM / RTL-SDR receiver.
IMPORTANT: You need to have an OTG capable Android device and a DVB-T-DAB-FM / RTL-SDR receiver, otherwise this application is useless. Search eBay / DealeXtreme for 'DVB-T-DAB-FM' to obtain one.
Before buying, check the list of Supported Hardware at: http://osmocom.org/projects/sdr/wiki/rtl-sdr
Also tested with the 'RTL-SDR Blog V3 R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio' and guess what... it WORKS! You don't need to use the calibrate functionality, just enter 1 as PPM-value and it works out-of-the-box!

It is an all in one application. This means that these 3 features are combined in one:
- Find the parts per million offset (PPM) of your DVB-T-DAB-FM / RTL-SDR receiver using the build-in utility;
- Receive the AIS data directly from air;
- Plot unlimited ships data and traces without delay onto a map (or send it to another application like OpenCPN).
