Microstockr is a mobile and desktop app that lets you track your stock earnings in real time. The mobile app currently displays the best selling agencies and daily sales charts. It also computes new earnings by finding the difference between the old and the new balance. Microstockr Pro, on the other hand, takes full advantage of laptop/desktop processors to provide a lot more features and insights into your portfolio. It figures out new sales by keeping track of every single one of them. Statistics are based on individual sales as opposed to balance difference.
