Perfect eggs,
every time.

EggTimer Max calculates the exact cooking time for your egg — based on its weight, starting temperature and exactly how you like it. Soft, jammy or hard-boiled.

Why EggTimer Max?

Not just a countdown — a physics-based model that gets your egg exactly right.

Science, not guesswork

Uses the Williams formula to factor in egg weight, fridge-or-room starting temperature and your target doneness.

From runny to hard

Dial in exactly how you like it — runny, creamy, soft, jammy, just-set, medium or hard-boiled.

Boil, steam, or cold-start

Three cooking methods, all solved with the same real calculation — plus a live boiling or steaming animation to watch while you wait.

Altitude-aware

Water boils cooler at altitude. EggTimer Max corrects the boiling point so timing stays accurate anywhere.

Cook a whole batch

Queue up several eggs at once, each with its own weight and doneness — every one timed individually.

Private by design

No account, no tracking, no data collection. Everything stays on your device. Works fully offline.
