ARC for Coffee Drinkers

You drink coffee every day but have never understood how it actually interacts with your sleep. ARC gives you the exact biological cutoff minute so you never sacrifice deep sleep for focus.

The Problem

  • Afternoon energy crashes despite drinking coffee
  • Difficulty falling asleep on days you have late coffee
  • Not knowing how much caffeine is still active at bedtime
  • Tolerance build-up over time

The Biological Solution

ARC treats caffeine like a pharmaceutical with a half-life. By visualizing your live caffeine decay curve, you know exactly when to stop drinking to protect your sleep architecture.

Key Features

  • Live SVG caffeine decay curve
  • Sleep-safe threshold prediction
  • Adenosine clearance wait timer
  • Custom drink mg logging

Your biology has
