Stock Guru is one of the best stock apps for daily traders, hands down. But if you fall into that category, you probably don't need me to tell you that. It provides information other stock apps just don't such as rick scores for several exchanges, volatility comparisons, valuation rankings, and so much more. This is the best mobile app for a new trader/investor like myself. The charts, education, and interaction with other investing tools and knowledge is the best I have found. If there is one drawback it is that the stock screener isn’t as customizable as I’d like, which makes it difficult to find stocks that match the criteria I need.
