What is a good app for investing in stocks?

There are several good apps for investing in stocks. I personally like Robinhood app for investment. It is available for free and with zero commission fee, it is ideally one of the most popular investing app available in the market. Some other good apps are:

• Spiking: Stock Exchange Market Investing & Trading
• Acorns – Invest Spare Change
• E*TRADE
• TD Ameritrade Trader
