About this app

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.

What’s new


Fix- Corrected an issue where alarms were playing the wrong sound on some devices.

This update improves timing accuracy, scientific calibration, and user guidance:

Bug fix - issue arising from how the thermal transition modelling using Newton’s Law of Cooling. The fix ensures that rest and cook times are now treated as distinct thermal phases.

Improved Calibration from Real-World Testing

We’ve added more spoken prompts to help guide you through the boiling process
