This ain’t your mama’s Fitbit.

A company in the UK has designed the “world’s first smart condom” — which uses nano-chip technology to measure performance and detect STIs.

The device, dubbed the “i.Con,” costs about $74 and is currently available for preorder on the British Condoms website, though it’s unclear when they will start shipping them out.

“Have you ever wondered how many calories you’re burning during intercourse?” the company asks in the product’s description.

“How many thrusts? Speed of your thrusts? The duration of your sessions? Frequency? How many different positions you use in the period of a week, month or year? Ever wondered how you stack up to other people from around the world? Welcome to the future of wearable technology in the bedroom.”

The i.Con is described as a wearable, micro-USB charged condom ring that can provide six to eight hours of “live” usage.

According to Mashable, the device uses a nano-chip and sensors to catalog numerous variables during sex — including penis girth, the “average velocity” and total number of thrusts per session.

It will also log other info pertaining to one’s health, such as calories burned and average skin temperature. British Condoms also claims that the i.Con can work as an STI indicator, thanks to its “antibodies filter” — which alerts the user when proteins or antigens, typically found in STIs, are detected.

Each device is made from synthetic rubber and contains a waterproof carbon fiber unit, which holds the nano-chip and sensors, Mashable reports.

They will be made in one size, with a “band adjustment feature,” the company says.

Once the user is done doing the deed, the data from their session is loaded onto their phone — either through the i.Con app or micro-USB port.

“All data will be kept anonymous but users will have the option to share their recent data with friends, or, indeed, the world,” British Condoms says. “You will be able to anonymously access stats that you can compare with i.Con users worldwide.”
