CookShelf vs S.D Timer Pro

Do you love cookbooks? Us, too. That's why we created CookShelf, the app that helps you make the most of your cookbook collection, and cook from the books you already own. Got too much zucchini in the summer, and an excess of cabbage in winter? Or are you just trying to find that one Bolognese recipe you love and make every year, but can *never* remember which book it’s in? Quickly find recipes across your cookbooks that use what you already have—no more forgotten vegetables wilting in your crisper drawer. Simply search by ingredient, dish type, or whatever you're craving, and CookShelf shows exactly which cookbook has what you need and what page it's on. CookShelf is built for home cooks who love real cookbooks and real creators. Set a goal for how many cookbook recipes you'll cook this year, track your progress, and look back at everything you've made. Plus, get inspired by what our community is cooking from the books you own. We bridge the gap between physical cookbooks and digital convenience—because the best recipes are already on your shelf. ◆ Instantly search across your cookbooks and thousands of online recipes ◆ Find recipes based on what's in your fridge ◆ See ingredients lists before opening your books ◆ See what people are cooking: browse real cooks from the books already on your shelf—what people made, the notes they left, the little tweaks that made it better ◆ Follow your friends: find the people whose cooking you trust and follow along ◆ Track your cooking: bookmark recipes, mark what you've cooked, add photos and notes, and look back at your cooks timeline ◆ Set a cooking goal and watch your progress grow throughout the year ◆ Reduce food waste: use up CSA box ingredients before they spoil ◆ Finally cook from those cookbooks you love but rarely open ◆ 16,000+ cookbooks indexed Join thousands of home cooks who are rediscovering the treasures in their cookbook collections every day. HOW DOES IT WORK? CookShelf includes both a free version and a Premium (paid) subscription. The free version lets you add up to 5 cookbooks and use all of CookShelf's features for those books—search, bookmarking, cooking goals, and tracking. Premium unlocks your full collection: ◆ Add unlimited cookbooks ◆ Search across your entire library and over 15,000 indexed titles You can start a free trial to access Premium. Unless you cancel at least 24 hours before the trial ends, you'll be automatically charged the price shown on the payment screen for your chosen plan. Your CookShelf Premium subscription renews automatically each month or year until you cancel. Canceling disables the automatic renewal, but you'll keep full access through the end of your current period. Deleting the app does not cancel your subscription.

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. PROFESSIONAL & HOME BAKERS Built for bakers who want repeatability and data-driven control over their sourdough process. Used by professional bakery instructors for workshop demonstrations and planning. No login required. Works offline once loaded.
