Look around your office tomorrow at 11:23 a.m. Are your colleagues totally absorbed in their devices?

Your coworkers might seem crazy busy — but they’re probably focused on getting busy. Turns out that 11:23 in the morning is the most popular time of the workday for people to check in with a dating app, according to a new survey from data security firm Wandera. 

The ease and mobility of dating apps have blurred the line between working hard and hardly working, the survey concludes, with a 69% rise over the past year in the use of Tinder, Bumble and other apps on work devices.

And while the pre-lunch hour is peak time in general for workers to take a swipe break, users of different dating apps tend to check in at different times. People on Match log on right after work at 5:20 p.m., while Tinder users get the itch during happy hour around 7 pm. Grindr guys see who’s out there at 11:55 p.m.

How much of a productivity suck is all this swiping? The average dating app break at work runs about seven minutes, the survey reports, and the typical user checks in five to six times a week. Thursday (when our brains start shifting into weekend mode) is the most popular day.

In total, dating app users lose an average of 47 minutes to browsing profiles and setting up a hookup. If you’re guilty of checking dating apps on the job, don’t worry about getting busted — considering their popularity, chances are your boss is logging on, too.
