Problem
In a shared fridge, nobody knows how old anything is.
Leftovers go in without a date, roommates forget whose is whose, and food gets thrown out too early or eaten too late. Labels and markers get skipped because they take effort every single time.

Interaction Design
One tap per day. The light does the remembering.
Tap to set
Six taps, six days. Each bright segment is a day left.
Counting down
One segment fades each day as the color drifts to orange.
Time’s up
The whole ring pulses red. Hold the center to reset.

Foam Mockup
What the foam model got wrong.

Hooking the cord was hard
The hook moved to the top corner as a wave crest the cord drops into, with the anchor holes on the bottom edge.
It tilted face down
Two feet on the back tilt the face up 5° on slanted containers.
Where to tap wasn’t clear
A raised circular target now marks the touch area in the center of the face.
