HOW THE ESTIMATE WORKS Unbuzz applies a simplified model to the drink amounts and times you log. The curve and cutoff are estimates, not direct measurements, medical advice or a diagnosis. Individual response to caffeine varies.

PRIVATE BY DESIGN The core calculations run on your device. Analytics are optional and off by default. There are no ads and no sale of personal data.
