A shower head that works with an App to help you cut down on all that water you're wasting

The Hydrao Smart Shower works with an app to track and manage water usage. Here, you set the thresholds. You can set profiles for different users and track water usage in the app, which may, in turn, encourage family members to change their water-usage habits.. Hydrao fits any standard shower head and doesn’t need batteries. Instead, it has a tiny turbine inside that uses the water flowing through it to generate enough energy to power the lights and the Bluetooth connectivity. The white shower head is equipped with built-in LED lights that can tell you, roughly, how much water you've used. The Bluetooth LE device connects to an iPhone or iPad app, which lets you set three alert intervals.
It's a gentle reminder of how much water you’re using.
