## Description

full rebuild to Swift

Stop guessing why you can't sleep. Caffeine Clock uses advanced half-life modeling to show you exactly how much caffeine is still in your system—long after your last cup.

Most people don't realize that up to 25% of their morning coffee is still active at bedtime. Caffeine Clock visualizes this hidden energy, helping you find your perfect "cutoff time" for better rest and consistent focus.

KEY FEATURES:

Real-Time Half-Life Graph See your active caffeine decline hour by hour. Know exactly when you'll be clear.

Smart Sleep Alerts Get notified if a late latte puts your sleep at risk. We calculate the impact based on your personal bedtime.

Personalized Metabolism Everyone processes caffeine differently. Customize your half-life sensitivity to match your body.

Focus vs. Jitter Zones Stay in the productive "Focus Zone" and avoid the anxiety-inducing "Wired Zone" with clear visual thresholds.

 Live Widgets Monitor your status right from your Home Screen and Lock Screen without opening the app.
