CurdClock: Cheese Making Timer
Rennet & Aging Tracker Guide
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Home cheesemaker? Get your exact curd cut time, rennet dose, and flip schedule. Flocculation calculator and step-by-step batch timer built for home cheesemaking.
Cheesemaking is all about timing — and one wrong cut ruins the whole batch.
CurdClock is a step-by-step timing and calculation tool for home cheesemakers. Enter your flocculation time, select your cheese type, and get the exact moment to cut your curd. No mental math. No guesswork. No wasted milk.
HOW IT WORKS
1. Add rennet to your milk and start the flocculation timer
2. Enter the observed floc time — CurdClock calculates your exact cut time
3. Follow the step-by-step batch timer through pressing, salting, and aging
FLOCCULATION CALCULATOR
The flocculation method is the most reliable way to time your curd cut — but it requires multiplying your observed time by a cheese-specific factor (2.0–6.0). CurdClock handles this instantly. Select your cheese type, enter the floc time, and a countdown begins to your exact cut moment.
RENNET DOSE CALCULATOR
Enter your milk volume, rennet type (single strength, double strength, or tablet), and milk type (raw or pasteurized). CurdClock returns the precise dose in teaspoons and milliliters, plus the correct dilution water amount.
STEP-BY-STEP BATCH TIMER
Follow 12+ timed steps per recipe — from heating milk through pressing. Change your start time and every step recalculates automatically. The same feature home cheesemakers have been building spreadsheets for. (Pro)
AGING TRACKER
Track multiple cheeses aging simultaneously. Color-coded status shows what needs attention today: green for on schedule, yellow for action due, red for overdue. Never forget to flip your Gouda or wash your Brie. (Pro)
