I was with Simple from the start and generally liked the app and the customer support (based in Portland IIRC) was very helpful and friendly.

My problem was that I had a large check to deposit and before they cleared it they insist I not only specify the source of the funds but also what I was going to use the monies for! I understand they need to ask the former (per IRS regulations and "Suspicious Activity Reporting") but the latter is frankly NOTFB and no other bank has asked me that question. I told them as such and closed the account.
