Many modern smartphones sport multiple rear cameras with different lenses, usually with a combination of zoom or wide-angle options. It allows the user to get a larger landscape into the shot or take high-quality pictures of something further away.
Expensive lenses typically use a magnet that sticks around the primary camera lens, while cheaper options use a clip that holds the lens to the back of the device.
One thing that can be said for phone's though, is that their own cameras are getting better and better. But certainly if you're planning on buying any of these lenses, you do want to test them first on your phone, and not just buy online, relying on those customer reviews.
