MOMO was never intended to compete with the traditional stock market scanner or screener. We love that you are comparing it to those heavy desktop apps, but we really designed MOMO to easily uncover stocks and track them "on the go" and incorporate into your watchlist and daily daily trading process — whether you used a scanner or not.
We've heard your suggestions and are working toward bringing more of the desktop options you are looking for in a mobile app, but we will always strive to be an easy to use "Stock Discovery" app versus an unwieldy, overly complex stock scanner/screener. If you have come here looking for a tool that has 500 different settings which require excessive daily effort and configuration, MOMO may not be for you.
