Caffeine Clock vs Caffeine Tracker

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.
