Secret of dating

And a separate study last year claimed to have revealed the 'sad' reality of online dating – that only a small percentage of messages on dating apps actually get a reply.

Led by Jennie Zhang from Oxford University, it found when women message first, men only reply 42 per cent of the time.

Reveal works in a similar way to the likes of Tinder and Bumble.

You browse photos and if you're interested, you swipe right - if you're not, you swipe left.

There is a 'pending' section for females that shows the guys they've swiped right on who are yet to make a decision.

Tinder's rival, Bumble, was created in 2014 with the intention of addressing the problem of 'ghosting', and was marketed as the first 'female-friendly' dating app.

It is free to use and its inventors plan to make money from advertising.

It discovered 33 per cent of men followed the strategy of liking all profiles while no females reported doing this.The researchers said that the trend might be explained by what is known as a 'feedback loop'.'Men see that they are matching with few people, and therefore become even less discerning: women, on the other hand, find that they match with most men, and therefore become even more discerning,' they wrote.There are even apps designed to take the hassle out of liking every profile on Tinder by doing it for men and a 'mechanical thumb' called Tinda Finger that can be attached to their phones to constantly swipe right on all profiles.You can tap on the photo to see additional pictures and hitting a button reveals additional information.Search settings allow you to set your preferences for distance and age range.
