There are times when our phones help us talk to someone when it’s important, and other times when some random person calls you while you’re trying to sleep. It’s not surprising that most of us out there wish that we could find a way to only let some people call us during certain times. With SemiSilent, you can now screen your calls in a whole new way.

This app will let you pick people in your contact list that you will allow to contact you. Anyone who doesn’t make the cut will not even set off the ringer on your phone. These calls will be politely and silently trafficked to voicemail. You can set special ringtones for different people, but being able to weed out who has the priority on your contact list is pretty nice. This app is free for Android users, and is great for those of us going into interviews, are on call, or just don’t want to be bothered unless we have to be.
