It does work but alerts and beeps continuously as you get close to a cam on another road. It is massively spammy, e.g. just told me there were 18 new cams but there weren't and I had to watch a minute of gambling ad before I could find out. The app absolutely eats battery and doesn't seem to close down. Not good on mobile cams, so a false sense of security. Just not enough advantages over Waze and Google Maps, so I've uninstalled.
