Elvie is a little bit different to the regular fitness trackers that we cover on Wareable. For a start, it measures your vaginal strength rather than your steps. And then there's the small matter that you wear it inside of you.
Yep, Elvie is a pelvic floor exercise device that is designed to sit inside a woman. But, unlike regular kegel gadgets, UK company Chiaro has embraced the quantified self movement by making Elvie connected.
So not only will it provide all the benefits of a standard kegel device, it also provides real-time bio feedback and gives an LV score within an app - both iOS and Android versions are on offer. It packs motion sensors that track the muscle movements during kegel exercises and tells the user whether they are performing them correctly.
Hardware turned hardcore: Sex and wearable tech laid bare
Elvie is a "ground breaking exercise tracker designed by women for women," explained physiotherapist Dr Kay Crotty.
"Strengthening and toning the pelvic floor can lead to improvements in core strength and control, improve strength of the back and abdominal muscles and can even better sex," she added.
The app features 5-minute workouts that, over time, become personalised for the user based on her performance.
Once you're done, Elvie can be discreetly packed away in its carry case, which also doubles as a charger thanks to its Micro USB input. You'll get two months of battery life from a single charge and Chiaro claims the device is "manufactured by the same people who make Jawbone, Apple and Beats products".
Elvie is available to pre-order now, and the sizing is customisable thanks to a silicon cap. It's Â£55 if you order in November, the regular price will be Â£95.
