I use Seeking Alpha (SA) whenever I plan to do some trading that day. The app is easy to use. I can quickly search for any sticker symbol to find a company. Then, I can glance through the company 's overall metrics (P/E ratio, market cap, dividend, profile, etc) as long as the recent reviews from SA authors. I like to update the "Notes" with my own information for references in the future. As long as I do my own trading, I plan to keep maintain my Premium plan with Seeking Alpha.
