There are plenty of smart wearable devices that can track your fitness activity. The ORing Plus is designed to track your sex life. It comes with custom vibrations and can track SpO2, heart rate, and your performance in the bedroom. This vibration ring has five strength levels and 3 preset patterns.
ORing Plus can track speed, thrust count, impact, and calories burned. The companion app for iPhone and Apple Watch lets you view your results and see how you stack up against others. This project is currently getting funded on Kikckstarter.
