Smart EggTimer

This application provides an egg timer which calculates the boiling time according to the formula derived by Dr. Charles D. H. Williams, based on required consistency, altitude, start temperature, and egg weight.

The formula is taken from here: http://newton.ex.ac.uk/teaching/CDHW/egg/

Get it on F-Droid

Instructions

If your phone does not have a built-in pressure sensor, place it at a position with GPS reception and wait until your altitude is shown.

Enter size of the egg. The preset egg sizes are as defined by the EU. You can change them in settings.

EU size S M L XL
Weight (g) <53 53..63 63..73 >73

Enter temperature of the egg.

Select desired consistency or core temperature.

Pierce the egg and put into boiling water. The egg must be fully covered with water. Let the water boil slightly.

Press the START button.
