Boil Eggs Precisely—Not Just With a Timer

Eggzactimer uses real thermal physics to calculate boil time based on your egg’s size, temperature, and start method. Whether you start cold or boiling, it models heat diffusion for perfect yolks every time.

Unlike generic timers, Eggzactimer adapts to your rest method, carryover heat, and even egg mass.

Conventional timers ignore key variables. Ice baths can over-chill. Boiling starts risk cracked shells. And unknown rest times lead to unpredictable results.

Stop guessing. Respect the egg. It deserves precision, consistency, and a timer built on science.

Built with Newton’s Law of Cooling—and a lot of eggs.
