Remember the Pavlok? It is an interesting wearable device that zaps you to help you break bad habits. It pairs with your iOS or Android device and triggers a stimulus based on activity, GPS, and sensors to help you change your bad habits. It is also possible to develop apps for the device.
Pavlok was crowdfunded a while ago. Now you have the option to order yours on Amazon. The device will be released on August 4, but considering the demand level for the product, you may have to wait a bit to get your hands on one.
