Kosher Scanner helps you check food before you buy. Scan a barcode or photograph the ingredient label to get a clear Kosher, Not Kosher, Uncertain, or Not Found result with the reason behind it. Built for shoppers who need a fast second check in the grocery aisle, while traveling, or when a package uses unfamiliar additives and E-numbers. What you can check: - Food barcodes and package labels - Ingredient lists from a clear photo - E-numbers and additives such as E120 carmine, E471 emulsifiers, E441 gelatin, E904 shellac, and dairy-related ingredients - Possible meat, dairy, pareve, or uncertain status - Kosher symbols or certification marks shown on packaging How it works: 1. Barcode scan: the app looks up product data and available label information. 2. Photo scan: AI reads the ingredient list or kosher mark from your package photo. 3. Ingredient analysis: the app checks known risk ingredients, E-numbers, animal-derived additives, dairy indicators, and source-dependent ingredients. 4. Result: you get a simple verdict with confidence, problematic ingredients, evidence used, and what to do next. Great for: - Shopping in US grocery stores - Traveling with unfamiliar brands - Checking snacks, candy, sauces, supplements, and imported products - Understanding E-numbers before buying - Asking whether an ingredient like gelatin, E471, whey, shellac, or carmine needs more verification Important limitations: Kosher practice can vary by community, certification authority, ingredient source, and manufacturing process. Kosher Scanner is a shopping assistant, not a rabbinical authority or official certification database. If the result is uncertain, if your community follows a specific hechsher, or if the product is for a high-stakes religious need, check the package certification and your trusted authority before relying on it. Privacy: Photos are used to process your scan and return a result. For best accuracy, photograph only the package, ingredient list, barcode, or kosher mark you want checked. Download Kosher Scanner and get a clearer answer before you put the product in your cart.

NEW: FULL BAKE PLANNER Plan the whole bake, from feeding your starter to taking the bread out of the oven. • 14 tested recipes: country loaf, challah, pitas, pizza, focaccia and more, with every ingredient in grams for the amount you choose • Tell the app when you want the bread ready and it calculates when each step starts. You can also plan days ahead, starting from the starter feed • A reminder for every step, including each fold, even when the app is closed • Choose how you bake: Dutch oven, baking stone or steel with steam, or a loaf tin. Times and temperatures adapt to your method • Oven timers: tap "I put it in the oven" and the app counts down every stage (lid off, drying and more). Every timer is editable • Guided path to build a sourdough starter from scratch, with daily reminders • In-app feedback form • English and Hebrew • No ads STARTER CALCULATOR Sourdough 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. Sourdough 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. SUBSCRIPTION Sourdough Timer Pro requires an auto-renewable subscription (monthly or annual). Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple ID account settings. Terms of Use: https://sd-timer-pro.web.app/terms.html Privacy Policy: https://sd-timer-pro.web.app/privacy.html
