But you should because ordinary folks can benefit when programmers can use Web technologies instead of writing apps that run natively on the dominant mobile operating systems: Apple's iOS and Google's Android. You may not care about what makes your app tick - so long as it ticks. Its success is a rare testament of the effectiveness of Web technology on mobile - an approach that Facebook Chief Executive Mark Zuckerberg called " one of the biggest mistakes if not the biggest strategic mistake that we made" in Facebook's initial foray into a mobile app. You can adjust sliders in the iOS version by tilting your phone or tablet to one side or the other, though there's a 16-megapixel file size limit.

With features matching many of those in Adobe Systems' Lightroom, which sets the standard for photo editing, Polarr lets you tweak color balance, adjust specific colors, fiddle with contrast using tone curves, and a lot more. Polarr goes well beyond the filters that countless other photo-editing apps offer to tweak a picture's color and mood. "One year ago, we couldn't have done this," said Polarr Chief Executive Borui Wang said of the new Web abilities. Polarr now sits atop the App Store ranking for best new apps, and is downloaded by iPhone and iPad users 111,000 times a day. Polarr broke from convention and utilized that Web technology as the foundation for its app, veering away from the idea of using code specifically intended to run on Apple's iOS software. But a photo-editing tool called Polarr may prove that thinking wrong. The Polarr image editor for iOS is built using the same Web technologies used by websites.Ĭonventional wisdom says that the technologies used to build websites are poorly adapted to the hotter and newer world of smartphone apps.
