Enter Happn, the app which finds the people you've crossed paths with throughout the day.
Half creepy and half ingenious, the app uses GPS tracking to present you with a list of people you've come into contact with.
The expert: This sounds like every stalker's dream, I'm not sure I would be convinced of its safety features, but it is a good way to make contact with someone who you've been eyeing from afar.
Happn allows for conversation only when you've both liked each other and you match.
Once solves that problem by providing you with one match per day.
The app combines digital dating technology and a team of human matchmakers, generating a specifically hand-picked match every day. You have 24 hours to decide if you like each other - if you match, you can go from there.
It will definitely encourage me to make the first move more often and it is empowering to be in the driving seat for a change.
The low-down: Have you ever seen Mr Dreamy on the bus only for him to get off three stops before you, vanishing forever?
