Rotzy … a social photo iPhone App

rotzyRotzy is a photo sharing iPhone application developed by Gee-Hwan Chuang and Gee-Hsien Chuang that lets you takeuploadshare, and discuss photos of life’s daily events and sightings with your iPhone. Gee gave a lightning demo of his iPhone application at a South Bay Tech Meetup.

The application allows you to take picture’s using your iPhone camera and then share and publish it to your rotzy gallery. It also allows you to broadcast photos to other sites like  Twitter, Facebook, and Tumblr. Gee described the gallery to be analogous to a twiter feed, with followers commenting on your pictures and initiating a long trail of conversation based on it. He mentioned that they had something else in mind regarding the direction of Rotzy, but it seemed to have taken the shape of a mini photo based social network with people spending a lot of their time commenting on the pictures.

Rotzy is a native iPhone Application available at the appstore. The back end for the application is  written in Python using Google’s Appengine.  They also faced some hurdles during the process of development for the AppEngine (See Gee’s Slide below). It was particularly fascinating to see their solution for working around the Location based search.  App Engine’s BigTable implementation does not allow easy latitude/longitude based searches and inequality based filters. So, they finally ended up using Geohash based hack to map up their locations.  The locations  that were geographically closer seemed to have a longer matching prefix for the computed hash value.

Overall, it seemed liked a well designed application that could even tap the social graph using the API’s of social networks.(Facebook Connect on Iphone)
