I like this app because it allows me to tap once to have it immediately begin recording video. In contrast, the iPhones built-in camera app requires me to call up control panel, tap on camera, slide to video, and select record (or if my screen is locked, slide up the camera icon, switch to video, and press record). If I want to quickly capture something, this app ("Record") is better than the built-in one. Also, control center often doesnt come up on my 6S so I enabled the accessibility option which requires an additional tap. If you have a few extra seconds, the iPhones default camera app is fine but for quick access this app works better than the default app.
