After acquiring the makers of Snapseed in September, Google (GOOG) on Thursday released the popular photo application for Android smartphones and tablets. Google also updated the iOS version of the app to add Google+ integration and some new filters, and it cut the price of the original app from $4.99 to free. Snapseed is a simple yet powerful photo editor from Nik Software that allows users to enhance images with various tweaks and gesture-based touch ups, along Instagram-like filters. Snapseed is available now for the iPhone, iPad and Android smartphones and tablets.
