It was only a matter of time before someone created a ‘Fitbit for your penis.”

Named Lovely, the sex toy links up with your smartphone and uses your data to recommend more than 120+ different sex positions and ways you can improve your sex life.

Lovely’s sex toy tracks things like calories burned during sex to the number of thrusts and your top speed. The toy also vibrates to help provide stimulation during sex.

The designers say its tracking software isn’t just for couples, but for all types of relationships.

Lovely sex toy is made out of body-safe, stretchy and smooth silicone and learns what you enjoy most in bed thanks to the built-in sensors and the feedback you provide to the Lovely app.

The Lovely app suggests positions based on your preference and helps you explore new areas of sexuality with your partner.

It connects to your smartphone via Bluetooth, and has a battery that lasts about seven hours when it’s not vibrating, or up at least two hours when it is vibrating.

Reid Mahako, a sex and relationship expert, says in the Lovely promotional video, “It doesn’t just have to go on a penis. You can put this wearable on a dildo, you can put it on your fingers, you can use it on a toy.”

Once your done having sex you can look at your smartphone and get advice on how well you did (Bad, Fair, Good and Cool Ranch).

“Over two years ago after particularly intense night with my partner we started wondering how many calories we just burned. I replied that there must be an app for that and actually started looking for it, but found nothing,” Lovely founder Jakub Konik told TechCrunch, “I did some more research, talked to sexologists, industrial designers and engineers, and realized that we could create a device that not only tells you how many calories you burn during sex, but actually understands your desires and helps you to pursue them.”

Originally priced at $169, Lovely is available for limited pre-order for $99, just in time for the holidays. You can pre-order Lovely sex toy here.
