About

Tired of soft eggs that turn out hard, and hard eggs that turn out... not quite? Eierkoch does the thinking for you. Instead of a one-size-fits-all timer, it calculates your egg's ideal cooking time from real physics — the same heat-diffusion model food scientists use. Tell it three things: • **Egg size** — from small (~48 g) to extra-large • **Starting temperature** — straight from the fridge or room-warm • **Your perfect yolk** — soft & creamy, medium, or hard Then comes the clever part: Eierkoch reads the **barometric pressure** right off your watch and adjusts water's boiling point to your altitude and weather. Up a mountain, water boils cooler and eggs take longer — most timers ignore this. Eierkoch doesn't. No barometer? It falls back to GPS altitude, then to a sensible default. Tap START and a clean countdown ring winds down on your wrist. At zero, a repeating alarm buzzes — time to plunge that egg into ice water. • Works completely offline — no phone, no account, no fuss • Built for round Garmin watches (fenix, Venu 3S, Forerunner 965 and more) • Crisp, hand-drawn graphics; available in English, German, French and Italian Breakfast, perfected. Made with love (and a few hundred test eggs). If Eierkoch saved your breakfast, you can fuel the next update here: https://buymeacoffee.com/matkramer
