HI Traffic Cams lets you view the traffic cameras on the Island of Oahu. You can add cameras to a favorites list for a quick glance at traffic conditions. You can also view road closures for all the Hawaiian Islands. Stay out of traffic by looking at traffic incidents and notices in the incidents view. This pulls in tweets using the #hitraffic hashtag.
This app does not and will never deliver annoying ads. It will also always be free. And don't worry, there are also no annoying "will you rate me" popups.
