Blur Background Photo Editor is a free iPhone app developed by Appic Stars LLC. With this app, you can easily blur the background of any photo using artificial intelligence.

To use the app, simply upload a photo from your camera roll and choose between the "photo" or "background" mode. Then, you can select from a variety of customizable blur effects, such as default, radius, motion, zoom, box, surface, and bokeh. The app uses advanced AI technology to provide you with a fully automatic result instantly.

Whether you want to add a blur effect to the entire photo or just the background, Blur Background Photo Editor makes it simple and convenient.
