How Leafclock Works
Made Visible, Made Reliable
Leafclock is designed to make textile usage visible.
Instead of asking users to remember how long a garment has been used, Leafclock turns usage itself into a visual signal — through a gradual, irreversible color change that reflects real-life wear and aging.
No apps.
No sensors.
No user action required.
Just a label that quietly changes as the product is used.

V1 · What Is Leafclock?
A smart color-changing label that indicates when textiles should be replaced.

The Complete Process
From first use to optimal replacement — how Leafclock guides the entire textile lifecycle
Step 1 · Usage Starts
When a garment is first used, the Leafclock label appears in its initial color state.
At this stage, the textile is within its optimal usage period. The label remains stable and unchanged under normal early use. This gives both users and brands a clear starting point — a visible "time zero" for the product's lifecycle.
Step 2 · Real-World Use Accumulates
As the garment is worn and washed, multiple everyday factors begin to take effect.
Washing and drying, light exposure, wear and friction, time and environmental aging — Leafclock responds to the combined impact of these real usage conditions, not to a single trigger or artificial signal. This is what makes the system reliable: it reflects how textiles are actually used, not how they are theoretically used.
Step 3 · Gradual Color Transition
Inside the label, Lifetracer bio-tracing technology drives a controlled molecular transformation.
Under repeated real-world use, the active molecular groups within the label gradually reorganize. This process causes the color to shift step by step — typically from yellow toward purple. The transition is progressive (not sudden), irreversible (not resettable), and visually intuitive (not abstract). This allows users to recognize early, middle, and late stages of a product's lifecycle at a glance.
Step 4 · Optimal Replacement Point Becomes Clear
As the color approaches its final stage, the label signals that the textile is reaching the end of its recommended usage period.
This does not claim to measure hygiene directly. Instead, Leafclock indicates when accumulated use makes replacement advisable — helping users avoid prolonged overuse. For brands, this creates a clear, consistent replacement logic that users can easily understand and trust.
Why This Approach Works
Many solutions try to detect hygiene.
Leafclock is designed to guide behavior.
By linking visible change to real usage accumulation, Leafclock avoids false precision while delivering practical clarity.
This approach has been refined through long-term development, repeated testing, and real market application — especially in high-usage textile categories.
It is simple on the surface, but deeply considered underneath.

Built for Focused, Long-Term Use
Leafclock is not a generic smart label.
It is the result of sustained focus on one specific problem:
helping people know when textiles should be replaced — without adding complexity.
This focus is what allows the system to remain:
Stable across washing cycles
Consistent performance through repeated washing and drying
Consistent across product batches
Reliable quality control at manufacturing scale
Trustworthy for brands operating at scale
Proven reliability for large-scale deployment
Quiet, precise, and dependable — the kind of technology that earns trust over time.
Custom Cycles Available
Leafclock's color-change cycles can be customized based on your product needs — from 30 washes to 50+ cycles and beyond.
