Just a DND add on
Nice UI but just a call grouping add-on to iPhones Do Not Disturb functionality. DND must be enabled for it to work - and it silences ALL text messages whether on contact list or not. So its basically useless if you want to avoid junk calls from strangers but still receive texts from people you know.
