What is the best paid application that will automatically set my volume at any desired times of the day? It must have multiple times and be flexible enough for me to enter in exceptions for Holidays. The problem is I have to have my phone on vibrate at work but if I don't take it off vibrate after work, I miss calls. I have looked at four or five free ones in the App Store and I would not try the paid version of any of them. They seem very buggy.
