Crustello vs S.D Timer Pro

Crustello is the smart companion app for the Crustello Starter Kit and Proofing Kit — helping you perfect your dough, sourdough starter, and every stage of fermentation with real-time data, alerts, and insights. Whether you’re cultivating a thriving starter or proofing dough for bread, pizza, focaccia, or pastries, Crustello takes the guesswork out of fermentation by tracking the things that matter most: rise, temperature, activity, and timing. Get instant notifications, monitor your dough from anywhere, and follow guided steps designed to make every bake more predictable and more delicious. • Track Fermentation Monitor your dough with complete clarity. The Crustello app records fermentation and shows graphs for dough, bowl, and room temperature, giving you full information over every stage of proofing. • Smart Alerts Never miss the right moment again. Set smart alerts in the Crustello app to notify you when your dough reaches peak rise, when the temperature falls outside the range, or even at custom stages of fermentation. • Sourdough Tracking Crustello makes it easy to know your starter’s rhythm. The smart bowl measures its growth, and the app’s graphs reveal the perfect moment to feed or use it, ensuring you always add your starter at peak strength. • Log Your Feedings Log every sourdough feeding in the Crustello app, including the exact ratios of starter, flour, and water. This makes it easy to track your routine, stay consistent, and see how different methods affect your starter’s growth. • History & Analysis Keep a complete record of your baking journey. Every dough and sourdough session is saved in the Crustello app, with detailed graphs you can revisit anytime to learn from past bakes and improve. • Data & Comparison See how your methods evolve over time. The Crustello app lets you compare recordings by overlaying graphs, making it easy to spot differences, refine techniques, and achieve consistent results. • Smart Calculator Plan your bake with precision before you even start. Enter your flour, water, salt, oil, yeast, or starter amounts along with fermentation times, and let the Crustello app calculate everything for a smooth, accurate workflow. • Connect Your Sensor Pair the app with the Crustello Smart Sensor via Wi-Fi and monitor from anywhere — even when you’re not home. You can connect and manage multiple sensors at once. The Crustello app works hand-in-hand with our Proofing/Starter Bowls and our Smart Sensor to provide a complete experience that helps you track your dough and sourdough consistently.

S.D TIMER Pro computes the exact feeding schedule for your sourdough starter, working backward from your target ready time to give you a precise feed time and gram-level recipe. HOW IT WORKS Enter six parameters: target ready time, quantity of starter needed (grams), desired hydration percentage, flour type, starter activity level (%), and ambient temperature (°C or °F). The app applies a fermentation kinetics model that factors temperature-dependent metabolic rates of lactic acid bacteria and wild yeast to calculate when your starter will hit peak activity. OUTPUT — YOUR FEEDING PLAN • Feed time: the exact moment to feed so your starter peaks on schedule • Starter / flour / water quantities in grams • Feed ratio (e.g., 1:9.8:9.8) • Estimated peak pH • Predicted flavor profile (mild, balanced, tangy, complex) • Recommended bread types suited to the resulting starter profile • Fermentation timeline chart with 80% activity window marked Set process alarms directly from the results screen to get notified at feed time and at peak. DESIGNED FOR PRECISION Temperature has a nonlinear effect on fermentation speed. A 5°C difference between summer and winter kitchens can shift peak time by 2–4 hours. S.D TIMER Pro accounts for this so your timing stays consistent regardless of ambient conditions. Supports both Celsius and Fahrenheit. Works across all flour types including whole wheat, rye, spelt, and einkorn. Starter activity input lets you calibrate for your specific culture's behavior.
