Eggzactimer

No more guessing. Boil eggs like a scientist (or a breakfast wizard).

Whether you're craving a silky soft yolk or a firm golden center, this app takes the guesswork out of egg boiling—using real thermal physics.
📏 Custom timing based on egg size, fridge or room temp, and start method
🥚 Drop your egg into cold water or boiling—your choice. Just tell the app what you're starting with.
❄️ Choose rest method: ice bath or room temp cooling, to dial in your final doneness precisely.
💡 Built on Newton’s Law of Cooling and real-world test data.


Why this isn’t just a timer:

Unlike stopwatch-based apps, this tool calculates how heat actually moves inside your egg. That means it adjusts boiling time based on:
- Egg size and mass
- Starting temperature (room vs fridge)
- Water start method (cold vs boiling)
- Carryover heat during rest
- Your target doneness: soft, medium, or hard
All modeled using physics, not guesswork.


Features:

✔️ Egg sizes: Small to Jumbo
✔️ Cold-start or boil-start methods
✔️ Fridge temp or room temp input
✔️ Rest method: ice bath or room temp
✔️ Doneness levels with preview temps
✔️ No accounts, no data collection, no distractions

✨ Built for precision. Styled with personality.
You’ll see the working scribbled on paper. Literally. Egg mass, carryover coefficients, and heat diffusion laid bare—complete with Newton’s Law and a few breakfast stains for good measure.

Created for cooks, scientists, and perfectionists.
If you've ever muttered “hmm, maybe 6 minutes this time?”—this app’s for you.
