This app looks like it could get alot of people into trouble if they interpret it as giving them some kind of permission to expense all their travel, meals, etc. You're only supposed to expense the items which were actually for business purposes, and no app can figure that out for you if your record-keeping throughout the year was sloppy. I don't think it will fly when you're sitting down uncomfortably with an IRS auditor if your defense is that some app told you to do it.
