Know your peak.
Skip the crash.
Log a coffee and see how it plays out: when you'll be sharpest, when the crash is coming, and how late is too late for another cup.
How it works
-
1
Take a short quiz
Weight, age, and how coffee actually hits you. That tunes the curve to your body.
-
2
Log your drinks
From your favorites, our database, or a barcode scan. A cold brew sipped over two hours behaves differently than a quick espresso.
-
3
Read your curve
See when you're at your sharpest, when the crash starts, and how much caffeine will still be around at bedtime.
