Apps like Thrill, Krush, Two Mangoes, Twine, etc draw information from users' Facebook profiles and answers to pre-set questions - like 'How will you spend a million dollars?' or 'What is your favourite dessert?' — to determine individual traits. These, in turn, become the basis for finding a match. "We make matches based on personality traits, and not the time or place of birth," says Rahul N Bhardwaj, creator of Two Mangoes, which has had seven lakh downloads since its India launch in April 2011.
