Lets you set preferred area and range (in miles) to search not simply a single city like many craigslist applications. You can set multiple saved searches and this application will notify you of any new post matching your criteria. Extensive options allow you to set notification times for wifi and cell networks and picture behavior to save data and battery. Works Great. One small feature I would like to see in a future update is checkboxes visible alongside thumbnails, instead of switching out of thumbnail view to see the boxes.
