I use this in conjunction with TomTom app on my iPhone 4. I turn off the TomTom camera alerts and rely on this better source of information.
New version allows you to launch a SatNav app in parallel to CamerAlert which saves a finger press. As I’m lazy that’s a great feature for me.
Database seems very accurate and is updated reliably even alerting you that you are out of date.
Wouldn’t drive without it!

Works well on the HTC Wildfire. I like it because it works, just using voice instructions with the screen off or with other apps in the foreground. It has a host of options to adjust for individual requirements.
