Device Motivates You to Save Water in the Shower
Eva shower attachment gamifies water consumption
There's an old story about how an elementary school janitor got the boys to stop dribbling urine on the restroom floor by drawing targets in the center of the urinals. Whether or not this is true, or just an urban legend, gamifying any task motivates people more than any other method. The Eva smart showerhead applies this fact to conserving water in the shower.
A crowdfunded device currently mid-campaign on Indiegogo, Eva screws on to your regular shower head the same way a detachable nozzle does. Once installed it, saves water in three ways.
