I purchased TidyCal a long time ago and recently started using it for my tutoring business. I had hesitations because of there not being phone support but I have been pleasantly surprised by the email support that has been there. They have always been responsive and timely and seem to take extra steps to help. One of the main workers I have had communication with is Srba Milenkovic. He has been very helpful and always has answered and helped me accomplish what was needed.
