Very basic, very slow

Not a great app.
Doesnt show key contact details unless you click to open the contact.
Have to rebuild the index every time you change contact data (takes ages and I only have 4,000 contacts).
Doesnt resort contact date unless you manually change the sort order and change it back.
On the plus side the search does seem better than the default iOS contacts app i.e. it does seem to search the notes field.
