Slør for iPhone
The Slør iPhone app can blur the background even more on iPhone photos taken in Portrait mode.
This works for the iPhone 7 Plus and iPhone 8 Plus rear cameras and for both cameras on the iPhone X. You need to be on iOS 11 or higher for this to work.
When you take the picture, you can then use controls to change the focus area and the amount of blur behind the subject. This can deliver incredible selfies with a beautiful blurred background and a sharp in focus face.
