There's been a lot of buzz on some of the podcasts I listen to about an online image editor called Polarr (http://www.polarr.co). I'd heard of it before, and even played with the iOS version a little bit, but I'd never really looked at the web version. I mean, why would I need to? I've got Lightroom and Photoshop and hoards of other image editing software. After hearing about it yet again, this time an interview with one of the founds of Polarr, I figured I might go ahead and give it another look.
There are a lot of neat controls available -- many of the things you can do in Lightroom's Develop module are present (including Polarr's version of dehaze), and they work well. There's also the ability to use presets, either some nice canned ones, or if you "sign up," you can save your own presets as well. Polarr can access your images either from your local hard drive, or from a variety of online sources like DropBox or Flickr. Images can also be shared to Facebook or Flickr, or saved to various cloud storage options directly from the editor. Of course, completed images can also be saved to your local drive.
The iOS app is a little different from the online version. To me, it's not quite as intuitive, but also not too different from the Photos editor that it's hard to use. There are limits, though, on the image source -- you can only load images from Photos or directly from the camera. There's also an in-app purchase option to activate the "pro features" mode
There's also a stand-alone version for Windows 10 (the only paid version so far, which sells for $14.99 and looks and functions exactly like the online version), and a Chrome version for stand-alone use on Chromebooks or computers with the Chrome browser and app-launcher installed.
So far, I've tried version 3 of Polarr on a Dell Core i7 Windows7 computer with Firefox, Chrome (Chrome app-launcher and browser), and Internet Explorer; an iPad Air 2 (iOS App -- the web version will not run on the iOS version of Safari); an Acer AspireOne netbook with Windows 10 (stand-alone and browser version using the new Edge browser); and the browser version on a new Apple Power Mac. All of them worked just fine (the netbook was a little sluggish, but it's always a little sluggish).
Here are some screen shots of the iOS version:
