As we near the release of the official 500px iPad app, here's a nice little third-party surprise to tide you over. The Pulpfingers
team released an app today based on the 500px API called ISO 500.
We're thrilled by its slick design and functionality and we encourage you to give it a whirl on your iPhone, iPod Touch, or iPad. It's available on the App Store now
and best of all, it's free!
