I have been using this for over a year now and find it to be spot on. Having just changed phones I emailed CamerAlert in the evening to change my details and the following morning it had been done. An excellent product with excellent back up.
I have this on my Home screen. It is really easy to use. It is updated every week! I have TomTom running in the background giving out directions & CamerAlert running in the foreground telling me where all the cameras are. The average speed camera function is very simple & straightforward. It doesn’t matter how many average speed cameras there are, the App knows where the first & last one is, and shows your average speed for that area. The best bit, is, if you are a member of pocketgpsworld.com & report a new camera site, you get free life membership.
