Scale any recipe to the servings you need and convert cups to grams in one tap. Your cookbook, a unit converter and kitchen math, all offline.
Cobble turns any recipe into the exact batch you need. Save it once, set the servings you want, and every ingredient recalculates on the spot — cups, tablespoons, grams, millilitres, ounces and pounds included.
Most recipe apps are built for browsing. Cobble is built for the moment you are standing at the counter with flour on your hands and a recipe written for six when you are feeding ten. It is a scaler, a unit converter and a kitchen calculator in one quiet tool, with no feeds, no sign-ups and nothing to scroll past.
WHAT YOU GET
• Any recipe resized to the servings you actually need, with every ingredient recalculated instantly
• Cups, tablespoons and teaspoons turned into grams, millilitres, ounces and pounds in one tap
• Your own cookbook with servings, prep time, cook time, category, steps and notes for every recipe
• Per-serving weights worked out from a total yield, so portions come out even every time
• Original and scaled ingredient lists side by side, so nothing is missed halfway through
• A scaled recipe shared to Messages, Notes or email in a single tap
PERFECT FOR
• Home cooks doubling a family dinner or halving a sauce for two
• Bakers moving between American cup recipes and metric scales
• Meal preppers batching a week of lunches from a single recipe
• Anyone tired of doing kitchen arithmetic on a phone calculator
WHY NOT JUST USE A CALCULATOR?
Because a calculator does not know that 1.5 cups of flour is 360 millilitres, that three-quarters of 2 tablespoons is a clean 1.5, or that a recipe written for 4 needs each of its twelve ingredients multiplied by 2.5. Cobble keeps the whole ingredient list in view, shows the scale factor, and rounds the way a cook would.
PRIVATE BY DEFAULT
Every recipe stays on your device. There is no account to create, no cloud to sync, no ads and no tracking. The app works fully offline — in the kitchen, at the cabin, on the plane.
FULL ACCESS
Cobble is a paid app. Full access is available as a weekly plan, a yearly plan or a one-time lifetime purchase. Subscriptions renew automatically at the end of each period unless cancelled at least 24 hours before the current period ends. Payment is charged to your Apple ID account. Manage or cancel subscriptions at any time in your device Settings.
Add your first recipe tonight and scale it to the exact number of plates on the table.
