Kelvin Sous Vide

Stop guessing. Start cooking with absolute confidence. Kelvin Sous Vide is the sous vide calculator built for home cooks who care about precision. Forget cross-referencing Baldwin tables, food-safety guides, and blog posts that all disagree with each other. Pick your protein, set your preferences, and get a scientifically grounded time and temperature result in under 10 seconds. HOW IT WORKS Kelvin uses real heat-transfer physics - Baldwin equations combined with pathogen pasteurisation D-values - to calculate a cook time specific to your exact cut, thickness, doneness level, and texture preference. It is not a static chart. It is a calculation engine that adapts to what you are actually cooking. WHAT YOU CAN COOK Choose from 7 protein categories with specific cuts: Beef: Ribeye, NY Strip, Tenderloin, Chuck Roast, Short Rib, and more Lamb Poultry Pork Fish Vegetables Eggs TWO AXES, TOTAL CONTROL Most sous vide apps confuse temperature and time. Kelvin separates them cleanly: Temperature controls doneness: Rare, Medium-Rare, Medium, Well Time controls texture: Firm, Tender, Fall-apart Adjust thickness with a thumb-friendly slider and Kelvin accounts for heat penetration to the center of your protein, not just the surface. BUILT FOR THE KITCHEN COUNTER Designed to be used with one hand, even with damp hands. Large tap targets, a dark interface that reduces glare near a hot stove, and zero loading screens in the calculator flow. All calculations are 100% offline and instant. YOUR COOK HISTORY Every calculation is automatically logged. See exactly what settings you used three weeks ago when that pork neck came out perfectly, and replicate it without guessing. Save your best cooks as named profiles for one-tap recall. YOUR UNITS, YOUR WAY Kelvin automatically detects your device locale and uses the right unit system - Celsius or Fahrenheit for temperature, millimetres or inches for thickness. Override either in Settings at any time. WORKS ON EVERY CIRCULATOR Anova, Joule, Inkbird, Sous Vide Supreme - it does not matter which one you have. Kelvin is completely hardware-agnostic. One app for every circulator you will ever own.
