Great Ap with Great Support

I just downloaded this Ap on Saturday to use at an outdoor event on Sunday. Instructions for set-up were good, and it was easy to navigate. I had one small glitch (a setting in my Authorize.net account). The iphone would show the transaction as declined, but it was being approved and recorded by authorize.net. I emailed Spartadata...I received an email back within a couple of hours along with a phone number to call. I spoke with Mike, who proceeded to troubleshoot and fix my setting within 2 hours (remember, this is on a Saturday!). I am extremely pleased with both the functionality of the program and the extraordinary customer support.
