RadarLive allows you to easily share radar sightings. While driving, you press "RADAR" if you see radar or let others know the coast is clear by pressing "NO RADAR". The data is shared in the cloud and you are alerted to radar sightings in your area as they occur. You get an audible alert, along with an icon on the map showing all activity in your area.
You can navigate to named locations, getting step-by-step instructions. Your favorite locations are saved for quick searching.
You can use Siri for totally hands-free operation.
