At the low price had low expectations but it works brilliantly.
Intuitive, reliable and regularly updated (if you pay yrly subscription). Interface allows you to quickly upload new cameras, which I did on a 2000 mile tour of France. Back a week and they have confirmed ‘free’ lifetime membership. This app provides a better interface and is more informative than any other speed camera database I have used. Recommend it – best bargain available.
