The Droplet app
Your water, finally visible.

Gallons used, flow rate, how long it’s been running and how serious it is, all on one screen.

Watch the flow live, minute by minute, until it stops.
Zoom from this minute to this year.

See where every gallon goes.
Droplet learns the signature of every fixture and appliance, then shows you what each shower, faucet, toilet and sprinkler used.
A tiny water line had been leaking for days behind our refrigerator. We had no idea and were quoted thousands for the repair.

- 3,000+ readings every minute
- 0.026 gallons per minute Caught as it happens, not in an overnight test.
Precise enough to notice what you don’t.
- A shower
- A faucet
- A running toilet
- A trickle you’d never hear
0.026 gallons per minute
The smallest flow Droplet can see.
Left running, even that adds up to about 37 gallons a day. Over 13,000 a year.
Why Droplet
Protection, without the tradeoffs.
Droplet side by side with the two other kinds of whole home water monitors: devices that strap onto your water meter, and valves plumbed into your pipe.
Automatic shutoff needs a valve cut into your pipe and a plumber to fit it. Droplet skips both. Want shutoff anyway? Connect Droplet to Home Assistant or MQTT and let it close a smart valve for you.
