Meet the HoofStep: a smart wearable device designed to monitor the well-being of horses. It uses sensors and your phone to alert you of events such as stress, activity, and pain. HoofStep is smart enough to show real-time position, movement, and behavior of your horse.
The main unit has sensors to register the smallest sensors. The app displays alerts when deviation from normal behavior. Expected to ship later this year. You can find this project on Kickstarter.
