ProtoDVR is a free dash cam application for Android devices that allows you to record videos while driving. With all the features of a typical camera device, you can feel safe on the road while recording evidence in case of an accident or saving precious memories of your trips. The app offers the ability to record videos in the background, so you can continue using your phone while still recording. You can also customize video length and quality, modify sound recording, and take snapshots during recording. With ProtoDVR, you can store your videos on an SD card or mark your most important videos as favorites to keep them safe. Accident recognition and tracking your current location on the map are also available features.
