THE NATIONAL.AE - Dec 30 - Harmonica is the only dating platform available in Arabic. "We're overwhelmed with the interest and data we've received," says Harmonica co-founder and CEO Sameh Saleh, 31, who has received 50 confirmed accounts of matches that turned into marriage proposals since the app launched in November 2017. He predicts that the actual number is at least 10 times as high. To join Harmonica, users complete a short questionnaire that resembles a first meeting with a prospective mother-in-law. After filling in a short bio and uploading a couple of pictures, the questions that follow ask users about a their degree, work, income and their religious affiliation. Users can't sign up unless they have an active Facebook account that is at least two years old. Given Harmonica's strong focus on monogamy, users are permitted to view no more than 10 potential matches a day. The plan is to expand the app regionally within the next three years.
