A crop of dating apps in smartphone-addicted Asia is offering to recruit friends for group dates or send along a chaperone to steer the course of romance.

While dating apps developed in the West encourage one-on-one, often no-strings-attached, meetings, many in Asia are as much about old-school courtship or friendship in a region where meeting a stranger in a bar can still be a taboo.

"My upbringing was very close to my parents, religious, traditional and old-fashioned," says Valenice Balace, who developed the Peekawoo service in the Philippines two years ago.
