EierUhr
Perfect eggs at any altitude
Free
Boiled eggs exactly the way you like them: calculated from egg size, doneness and starting temperature – corrected for the boiling point at your altitude.
EierUhr calculates the perfect boiling time for your eggs instead of guessing.
Choose the egg size, how you like it and whether the egg comes straight from the fridge or is at room temperature. EierUhr uses a physical heat-transfer model to calculate the time the yolk needs to reach the right temperature.
COOKED RIGHT, EVEN IN THE MOUNTAINS
Water boils at a lower temperature the higher you are. EierUhr uses your location once to determine your altitude and the resulting boiling point of the water, and adjusts the boiling time accordingly.
