Nevertheless, many are familiar with Instagram as "the app that distinctively confines photos into square shapes" and pays homage to film-based Polaroid and Kodak cameras of the past. The service currently sees over 30 million users on Apple's iOS platform (iPhone, iPad, iPod touch) and allows users to link their Twitter, Facebook, Foursquare, and Tumblr accounts for additional photo sharing priviledges.
In terms of functionality, the Android application itself is identical to its Apple iOS cousin, featuring simple flash controls and a camera-switch button to alternate between front-facing and rear-facing cameras with a single tap. Unfortunately, the application still lacks spot-focusing, cropping and zooming after a picture has already been taken.
As we've mentioned, Instagram is particularly catered towards those special personalities with a love for photography aesthetic and mobile photo sharing. While we admit it isn't the best application for high-end photo enhancement on the go (see: Adobe Photoshop Express, Google Picasa, Path), it makes for an interesting addition to any iOS or Android user's application portfolio.
Instagram for Android can be downloaded from the Google Play store here.
