Log your coffee. Track caffeine in real time. Stay in control of your energy, focus, and sleep
That afternoon espresso might still be affecting you at midnight. Caffeine has a half-life of about 5 hours, but most people never think about what that means for their body. Mr. Caffeine does the math for you.
Log your coffee, tea, or energy drink with a single tap. Mr. Caffeine calculates how much caffeine is still in your system in real time and shows you how it affects your energy, focus, and sleep.
HOW IT WORKS
Caffeine doesn’t disappear after your last sip. It stays in your system and fades over time. Mr. Caffeine tracks this process using a caffeine half-life model, showing you a clear decay curve throughout the day. You’ll always know where you stand and whether that next cup is worth it.
