He is still single and looking - but mostly at his mobile phone.
Singles in Singapore are looking for friendship and love on dating apps, which are mobile-based and usually free.
Ms Wendy Tse, 33, founder of Blindfold who also owns match- making agency Society W, says: "Not only does this model give users anonymity from friends, colleagues or bosses who might also be on the app, but it also means people connect on a level that is more than just superficial." She adds: "Users who have matched up can reveal their photo to each other when they feel comfortable." These special features have allowed such new apps to take off in a big way.
"I think getting to chat first is a great asset if you're shy about making the first move in real life." Paktor may have impressive user numbers, but Mr Chua Joo Hock, managing director of Vertex Ventures, a global venture capital platform which has invested up to US$10.5 million (S$14.1 million) in the dating app, estimates that Singapore is three to five years behind the United States, which is at the forefront of online dating, in terms of online dating social acceptability.
Still, he says the industry of bringing new people together socially represents a fast-growing US$1 billion-revenue-a-year market in Asia.
Similarly, Blindfold, though launched in beta only in October, has made more than 30,000 matches.
So does this mean that the old- fashioned face-to-face pick-up line is dead? For users such as student Mohita Jain, 23, dating apps have their time and place, but after a while, can ironically become work.
He adds: "There is an upward trend in the adoption of online dating by more traditional-minded Singaporeans in recent years." Dating apps may have encouraged a more lively and casual dating scene, but they have also created a new set of concerns regarding safety and harassment, especially of female users.
Websites and blogs have sprung up in the wake of Tinder's boom, documenting the unprompted and unwilling advances that women have to deal with.Instead, they emphasise security and are more attentive to the needs of female users.For the three Korean-American sisters behind the San Francisco- based app Coffee Meets Bagel, the experience of their female users was key.According to the report on General Household Survey 2015 released by the Department of Statistics early last month, the proportion of singles among residents aged 25 to 29 years rose from 74.6 per cent to 80.2 per cent for males and from 54 per cent to 63 per cent for females, between 20.Ms Shn Juay, regional marketing director of Singapore-based dating app, Paktor, says one reason for the boom in dating apps is that "millennials like things to be quick, easy and convenient".Mr Oh, who has gone on more than 10 dates in the past eight months, says: "Sometimes, a conversation on Tinder doesn't go anywhere, but does that really matter when there's always someone else to talk to?
