Caffeine & Sleep Optimizer

Your last cup has a deadline. Find it. Stick to it. Sleep better tonight.

You already know coffee keeps you awake. But do you know exactly when to stop?

Most people just guess — avoid coffee after 3pm, or drink it anyway and hope for the best. Caffeine & Sleep Optimizer takes the guesswork out with a personal caffeine cutoff calculated for your bedtime and sensitivity level.

YOUR CAFFEINE DEADLINE Tell the app when you go to bed and how sensitive you are to caffeine. It calculates your personal cutoff automatically. Green means you're good. Yellow means your window is closing. Red means coffee is done for today.

SLEEP CALCULATOR Waking up well isn't just about how many hours you sleep — it's about when in your sleep cycle you wake up. The app calculates the best times to fall asleep or set your alarm using 90-minute sleep cycles, so you surface in a light phase instead of the middle of deep sleep. When to sleep — enter your wake-up time, get the best bedtime options When to wake up — enter your bedtime, get the optimal alarm times

DRINK TRACKER Log every caffeinated drink with one tap: espresso, americano, filter coffee, black tea, matcha, energy drinks, cola — or create a custom drink with your own mg value. Watch your daily caffeine total update in real time and know exactly where you stand before your next cup.

PRO VERSION Unlock unlimited custom drinks, monthly statistics, sleep-caffeine correlation charts and deeper personal insights into your habits. Find your cutoff. Sleep better. Feel the difference tomorrow morning.
