In Short: Car Camera is a new application that surfaced on the Play Store quite recently, and after 23 reviews, it's holding a 5-star rating. This application's purpose is to transform your smartphone into a dashboard camera, basically, and save you some money, as you won't have to purchase a regular dashboard camera if you start using this app. There are two versions of this application in the Play Store, a free (trial) one, which will offer you 14 days of using the app until you're asked to buy a Pro version, and the Pro version will actually require you to make monthly payments in order to use the app.
Background: Having a dashboard camera in your car is always a good idea, as it will record everything that is going on in front of you (or even in the back as well, if you point it that way). It will record the traffic in front of you just in case you, or someone in front of you gets in a car accident, that way you can show what happened to the police, and avoid false accusations by other drivers and what not. There are a ton of dashboard cameras available out there these days, but good ones aren't cheap, well, for only $5 you can get your smartphone to start acting like a dashboard camera. This app is especially useful if you have a secondary device that you're not using frequently, or at all, as you can basically give it new life this way.
Impact: User interface on this app is similar to the one you'd find on most regular dashboard cameras, so if you've ever used one, you'll be right at home here. In addition to recording what's going on in traffic, this app will also keep track of your location and trajectory via Google Maps. You can set a max recording time in this application, while you can also capture time lapse videos as well, if that's what you're into.
