Conducting ambient odour surveys is easier than ever with the PlumeMapper app! Gone are the days of pen and paper, with PlumeMapper, simply plot odour observations on your mobile device using your GPS location. Users can record Static (timed) and Dynamic (instantaneous) measurements following the European EN16841 and German VDI3940 standards. Intensity and hedonic tone follow the German VDI3882 Part 1 & 2 ranking systems, as well as the EPA Victoria (Australia) approach. PlumeMapper assists you to develop a comprehensive picture of odour nuisance in the area. All your survey data is sent to a centralised location, eliminating the need for manual transcription of paper data into digital formats that are difficult to track. The PlumeMapper suite requires an active account. Go to plumemapper.com.au to learn more.

Verdict
The clearest difference is update cadence: Hardkorr at fortnightly against PlumeMapper's monthly. PlumeMapper's advantage is device support (3 vs 1) and iOS requirement (15.5 vs 17.6). On price, ads and in-app purchases there is nothing between them.
