After leaving my Blackberry behind, I discovered I only had 2 ringer profiles on my Samsung; default & vibrate. I desperately needed a solution. I found this app and I love it. It works exactly as I expected. It comes with 4 profiles already setup, or you can create your own profiles. Another feature I love, and wasn't on my Blackberry, you can also schedule a time for a profile to start, like at bedtime when I want incoming phone calls, but don't want to wake up to a spam email in my inbox! I placed the app on my Idle screen and a simple click to open, select the desired profile, click "Active", it will take a few seconds to active a selected profile. Now you can create a profile for any occasion.
