If you asked me to describe the TouchRetouch app in one word, I'd say it's magical. We've covered this photo editing app a few months ago, but it's worth a second look. It's also a universal app, so that means you can buy it once, and then download it both on your Windows and Windows Phone devices. What does it do? It lets you remove unwanted objects like smudges or people out of the picture. Want to see it in action? Watch our hands-on video on the Surface Pro 3 and the Lumia 930.
