'Previous research has shown that humans signal their romantic interest in several different ways, including non-verbal behaviours and body language.'

Figuring out whether you need to break up with your partner or just work harder at the relationship can be terribly difficult.

Now just a few taps of your phone could give you the answer – or at least bring you far closer to making a decision.

Chicago-based programmer Sarah Gray created the app Should I Break Up With My Boyfriend? when working through a tumultuous relationship several years ago.

Gray said she realised she was up and down on a daily basis and wanted to track her feelings about the relationship from an objective perspective.

The clever app requires girlfriends to rate how they feel about their significant other.

It then analyses the data and reveals how the user’s feelings fluctuated in comparison to their general outlook on life.

Gray said: “Being able to see your relationship clearly and objectively is the first step on the path to a happy, healthy, love life – whether it’s with him, with someone else, or on your own for a while.”

Feelings graphs can help you figure out whether you spend most of your time together feeling happy or sad. “Sometimes, we need an objective voice to help us appreciate a good thing or accept something painful. And this app helps us tap into the best voice of all – the one inside ourselves.”

The app warns that it cannot replace “discussions with a licensed therapist, a best friend or a favourite pet”, but it can certainly provide a fresh point of view. Users can also share results with trusted friends via e-mail or SMS.

The conflicted dater is not able to look at their own results for a whole fortnight, so their answers will not be influenced by their most recent feelings.

When viewed afterwards, developers MercuryApp hope the patterns will have more impact and help provide answers.

Gray’s own results showed that her mood was “good” only 39 percent of the time and neutral for the rest.

In the end, Gray believes that this simple but scientific analysis helped her to end a rocky relationships and move forward for good. – Daily Mail
