Silent Camera is a camera app that stands out for the fact that it doesn't make a sound, even when your Android smartphone is not on silent. When you take a photo with this app, there is no shutter click or sound of any kind.
Although its main draw is its lack of sounds, Silent Camera offers so much more. For one, it includes several focus modes: autofocus, manual focus, and macro. There's also a timer that you can set to three, five, or ten seconds. You can even correct the white balance or apply colored filters to see how they look in real time.
Once you take the photo, you can retouch it before saving it on your smartphone. There are more than a dozen different filters at hand, as well as the ability to adjust brightness and saturation. Once you're satisfied, then you can save the photo.
Silent Camera is a good camera app for capturing moments without drawing attention to the fact that you're taking a picture. Even better, in the settings, you can choose which button you want to use to take photos.
