Green Caller

Sometimes we need phone in silent mode. For that reason we miss all phone calls from others even some important phone also. such as family, office or some very important person. We can overcome this situation by using green caller app. By this app user can be able to add some number as green number. Only green number phone will ring here. other all others number will be in silent mode.User also can set auto deactivate time, after this time app will be automatically deactivated.
