• 500px Android app is here! | 500px
  500px just released their Android app and that's great news!
  Sure there were a few third party apps on Android Market (or Play Store, as now it's called) but I feel an official mobile app should always be made in-house, to be related to the main application(even if it just means to share all the branding and logos).
  I honestly believe that online services should always have a way for programmers to build stuff around it (a public API), but for me that has two main purposes: create clients for smaller platforms or, the most important, create mashups and alternative ways to browse and use the information of those services. A fine example of that is Flickr, with hundreds of original apps but when iOS and Android started to gain traction official apps were releases.
