The installation is a bit messy, but like most PSILoc+ software, the actual application os of a very high quality and tightly integrates with the system.
In case you're not accustomed to the concept, this application lets you schedule profile changes, so if (for example) you have a business meeting every Monday morning from 9:00am to 10:00am, you can tell Extended Profiles to switch your phone to Silent for that time. Thus, you no longer have to remember to do it yourself.
It's set to be priced at $9.95, so happy profiling!
