Portfolio-style apps that allow you to show off photos and images in a clean, professional manner abound, but in our experience, quality is hit or miss – mostly miss. Portfolio is one of our favorites since it puts the emphasis on the photos themselves and not on app-based bells and whistles. An especially nice touch for pro photographers: You can set up the app with personalized branding so the albums it produces have the look of a custom-built product. [$12.99; iOS]
