I tried Acorns a few months ago. After the first month I gave up and moved my money else where.
I have heard of a number of user complaints about the fees being taken out of the users bank account directly - instead of the balance in Acorns (clear user information needed around this). Plus I am worried about Acorns using my credit card data
