There are plenty of smart wearable devices that monitor your activity and track your notifications. doppel is a different kind of wearable device though. It works with your body’s response to rhythm to improve your performance, change your mood, and help you keep up with the world. You just have to set the right pace.
doppel does not make a whole lot of noise but has a pulse that helps you set the right pace for your body. Once you have calibrated the device, you can use the companion smartphone app to fine-tune its settings. The battery life lasts 5 hours. You can find out more on Kickstarter.
