Shower sensor timer and app

Showers that cost you and the planet less
Shorter showers are one of the most impactful ways to conserve water and energy as hot water is the valuable water. Most people take ~8-10 minutes to shower, but for others this can be even longer. 4 minutes is the duration recommended by utilities for sustainable showering.
ShowerStar is an award winning purpose built sensor timer for showers that completely reimagines the basic shower timer using behavioural nudges to prompt people to take shorter showers:
2 minute DIY install onto existing shower.
Auto-flow detection - no manual input.
Real time "traffic light" alerts that everyone understands.
Logs showers - clear simple digital log of shower dates
and duration.
Visualise water and energy use and costs.
Using ShowerStar behavioural nudges on a daily basis typically delivers a reduction in shower time of 2.7 minutes or ~30% per shower.

Your daily choices matter
You may think your daily choices don't matter, but when we act together, our collective impact across society and the environment can be huge.
Many of us spend much more time in the shower unaware of the amount of water and energy we're consuming.
Many Gen Z teens are water and energy illiterate and not having to pay bills frequently results in 20-30 minute or longer "Everything Showers" that have taken TikTok and social media by storm.
Aside from the costs, long showers also often use up the hot water leaving others to take cold showers adding to family friction.
Shorter showers can deliver $600-$800 a year and sometimes more in savings for many families. Shorter showers are good for the environment, reduce our carbon footprint and conserve water for our communities.

Hot water is our most expensive water
