rysasahrialSmart EggTimer is an Android-based egg timer app designed to help you cook eggs perfectly every time. Leveraging the scientifically proven formula from Dr. Charles D. H. Williams, this egg timer calculates precise boiling durations based on egg weight, initial temperature, desired doneness (soft, medium, or hard yolk), and local altitude. Whether you’re aiming for a runny breakfast egg or a hard-boiled snack, this boiling timer ensures consistency and culinary accuracy.
Why Smart EggTimer is Your Go-To Egg Cooking Tool
- Precision cooking: The app integrates a real-world boiling time formula so you can consistently achieve the right egg doneness (soft, medium or hard).
- Altitude adjustment: It uses your device’s GPS to measure altitude—critical since water boils at different temperatures depending on elevation—making this a smart altitude-aware timer.
- Customizable egg sizes: Includes EU standard sizes (S, M, L, XL), but you can manually adjust weight settings for personalized use.
- Temperature input: Enter the starting temperature of your eggs to fine-tune boiling time for fridge-cold or room-temp eggs.
- Simple interface: Just pierce the egg, drop it into gently boiling water, and tap “Start.” The timer guides you through to perfect doneness.
- Privacy-first design: The only permission required is GPS (for altitude); no data is sent to the internet.
Smart EggTimer is ideal for kitchen enthusiasts, meal preppers, and anyone focused on perfectly boiled eggs, this app doubles as a travel-friendly portable egg timer—no bulky accessories needed. With over 112 GitHub stars, it’s a favorite among developers and cooking fans.
