Leafclock
A smart color-changing label that tells you when clothing should be replaced
Leafclock visually indicates fabric aging through gradual color change — helping brands and consumers know when it's time to replace, not guess.
The problem with textile replacement today
Most clothing is replaced based on habit, guesswork, or discomfort — not actual usage.
Overuse that risks hygiene and comfort
Without clear signals, products are often used beyond their optimal lifespan
Premature replacement that creates unnecessary waste
Guesswork leads to replacing items that still have useful life remaining
No clear signal for consumers, and no feedback loop for brands
The disconnect between usage and replacement creates inefficiency for everyone
Leafclock makes textile aging visible
Leafclock is a smart wash label that gradually changes color as garments are washed and worn.
The color shift serves as a simple, visual signal — indicating when a product has reached its optimal usage period.
No apps. No scanning. Just a clear signal users can see.

How it works
Before use
The label starts with its initial color when the product is new.
During regular use
Washing, friction, light, and daily wear gradually trigger a color shift.
Optimal usage reached
When the indicator color matches the reference, it's time to replace the product.
Why Leafclock matters
For consumers
Clear replacement signals improve hygiene, comfort, and peace of mind — without asking users to remember or guess.
For brands
Leafclock adds functional value to everyday products, strengthens user trust, and creates a natural replacement rhythm that supports long-term customer loyalty.
For the planet
By making textile lifecycles visible, Leafclock helps reduce premature disposal and unnecessary overuse. Better replacement timing means less waste, fewer guess-based purchases, and more responsible use of textile resources.
