Here is the NCDXF page that lists a lot of Beacon Trackers of various sorts. http://www.ncdxf.org/beacon/beaconprograms.html

These two programs use a radio interface to automatically tune a radio to the beacon schedule and frequency then use digital signal processing to detect the NCDXF beacons and plot the signals on a map:

BeaconSee, 25 British Pounds.  https://www.coaa.co.uk/beaconsee.htm

Pharos, $25 US Dollars. https://www.coaa.co.uk/beaconsee.htm

Faros by Alex VE3NEA is pretty good, I haven’t seen BeaconSee run.
