The Google Play store has a new section: the Free App of the Week. The tab features an app that is usually paid but is offered free of charge for a limited time. The move is likely to boost downloads for the selected app, but there is no word on how mobile development firms can apply to become the free app of the week.
Google has recently made several changes to Google Play, and it is likely that more will be coming in the lead-up to the Google I/O development conference in May.
