Stonder is a new Android application that offers a simple, fun, and visual way to follow the stock market. Developed by Luuva Oy, Stonder is a crowdsourced platform that collects investor opinions on individual stocks and turns them into consensus and insight to help users find interesting companies. With Stonder, users can visualize market sentiment and changes in sentiment, see opinions on smaller companies with no analyst coverage, and learn from the best by checking out the picks of the best-performing users.

Stonder creates a synthetic portfolio for each user based on their opinions, and each stock has an equal weight. The app calculates the performance of each portfolio and tracks the performance against the market and other users. Users can also track their own performance relative to the market and other users. Stonder offers a range of features, including 1, 7, 30, and 90-day top portfolios showing the best users, 1 year price history for individual stocks, and 1, 7, 30, and 90-day performance history for each individual stock.
