There are many other better and cheaper apps for investing. Stash held my money for 3 days during a Sell for no reason other than to keep the cash since theyre legally allowed to. The fees per month are way higher than anywhere else for small account. That $1/month could be 100% of your investment if youve only invested that much! It should be based on percentage not flat rate.
