Use https://play.google.com/store/apps/details?id=au.com.securehub.ozradar2
I've fixed this app but am unable to replace this version so have created a new version https://play.google.com/store/apps/details?id=au.com.securehub.ozradar2.
Unfortunately the Google app search does not prioritise results with matching names so if you search for "Oz Radar 2" it will only appear unless it it is in quotes 😕
