Cropping has the potential to turn a good photo into a great one, or even save a shot that would otherwise have ended up in the digital trashcan. Software company Polarr has now launched a new AI-powered app for iOS that should make finding the perfect crop much easier.

Deep Crop's algorithms have been trained to find the most interesting elements in a photo using

using 200 million cropping data points from real photographers.

The company also says it has achieved an 20x efficiency boost in RAM and power usage for offline AI- systems, allowing for the app to run locally on your iPhone. This means there's no need for internet connectivity and your image material won't be uploaded to any external servers.

When you launch the app, all images in your camera roll will be displayed, and tapping on a photo will show you suggested crop options. By default, you'll see smart crops of various ratios but it is also possible to specify an aspect ratio.

If you don't like the apps' suggestion you can repeat the process as many times as you like to see more crops. Once you like the result it can be exported or shared in the usual ways.

In its current state Deep Crop is pretty much a one-trick-pony but we'd expect the technology to be integrated into one of Polarr's more comprehensive applications, such as Photo Editor, at some point in the near future. In the meantime the app can help you achieve better crops or simply discover new perspectives when viewing your own images.

Polarr Deep Crop is available on the Apple App Store now.
