Water boils cooler in the mountains, so the same egg needs a different time in Denver than at the coast. Egg Timer uses your altitude — from GPS or set by hand — together with the real physics of boiling water to get the cook time right, from sea level to ski lodge.
• Dial in exactly how you like it: a slider sets doneness from runny to firm, mapped to the yolk temperature.
• Pick egg size (S–XL) and starting temperature, fridge or room — the time updates instantly.
• Cook several eggs at once, each at its own doneness (Pro).
• A reliable alarm goes off right when your egg is ready, even with the screen off.
• Save your favourites and cook any past egg again with a single tap.
• Light & dark themes, lovingly made seasonal looks, °C or °F.
