GTX Facepaint review for Data Export IO: Reports

I have been using for a few weeks now. Its really easy to make the reports that you actually need and you can make custom fields (i.e. a field that is actually the value of 2 or 3 other fields combined). Also the customer support is almost instant. Whenever I have needed a field that doesn't seem to be available they create it for me and add it to my spreadsheet for me. I am very happy with the app and the service.
