Scanner Pro, which lets users scan documents, receipts, and more using their iPhone or iPad, recieved a big update to version 4.5 this week. The update enables live border detection, which allows the app to intelligently find the edges of whatever is being scanned while you photograph it.

In our testing, the border detection was very accurate, although it did have a bit of trouble when the paper and the background where different shades of the same color. The app does still allow you to manually edit the borders to fit the document perfectly, just in case there is a detection error, so any small problems are easy to correct.

The app itself is well-designed and features a solid storage solution for your documents. Multi-page scans are supported and you can save everything to a variety of cloud storage services, including iCloud, Google Drive, Dropbox, and more. You can even fax scanned items right from your iOS device.

Scanner Pro 4.5 is available now on the App Store. Existing users get the update for free, while new customers can get it for $6.99.
