S.D Timer vs The Bake Log

S.D TIMER 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 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.

Never lose track of your sourdough starter again. The Bake Log is the simplest way to keep your starters alive and your bakes consistent. Feed your starter, plan your bakes, log every loaf and watch your skills improve over time — all without an account. Your journal lives on your phone, and its backups in your own iCloud Drive, nowhere else. PLAN YOUR BAKE BACKWARDS - Choose when you want it out of the oven, and every step is laid out behind that time - A reminder tells you when it's time to wake the levain - Your starter knows the plan: feed it for the bake and the app offers to start it - Missed a plan? Plan it again for next week, or let it go - Bake Again sets up the same bake for the same time next week MORE THAN LOAVES Sourdough isn't just bread. Log pizza, focaccia, bagels, rolls and enriched dough, each with its own guided steps and piece counts. Whatever you're baking, The Bake Log keeps the recipe, the timing and the result in one place. FEED YOUR STARTER - A sourdough starter tracker for one starter or many, each on its own feeding schedule - A countdown tells you when the next feeding is due - See at a glance whether your starter is vigorous, healthy or sluggish - Record every feeding with flour, water, ratio and a photo GUIDED BAKE — YOUR RECIPE, ONE STEP AT A TIME - Stop setting six phone alarms per loaf — it pings you at each fold, shape and bake - Walk the whole bake day, from mix to oven, at a calm pace - Coil-fold and stretch reminders fire on time — even with the phone locked or after a reboot - Live countdowns for bulk ferment, proofing and cold retard, on your Lock Screen, in the Dynamic Island and at the top of every screen - Advance early when the dough is ready — the dough decides, not the timer - Your measured times flow straight into the bake log when you're done LOG EVERY BAKE - Hydration, bulk ferment, dough temperature and proofing time - Rate taste, crumb and crust, and see which recipe performs best over time - Add photos of the crumb and the finished loaf - Every bake gets its own page: the day it went through, step by step - Fold seeds, olives or a share of rye into any recipe with add-ins — your hydration stays accurate BUILD YOUR RECIPE LIBRARY - One page per recipe: read your method at a comfortable size and see baker's percentages - Scale any recipe by the loaf, the tray of focaccia, or the piece for pizza, bagels and rolls - Filter by bake type, and share a finished bake as a card EARN BAKER'S MARKS A quiet shelf of milestones you earn for every loaf, every feeding and every patient overnight prove. Nothing to chase — just a record of how far your baking has come. YOURS, AND ONLY YOURS - No account, no sign-up, no server — your starters, recipes and bakes live on your phone, and it all works offline - Your journal, photos included, backs up automatically and free to your own iCloud Drive, in a folder only The Bake Log can see - Each device keeps its three newest backups; we never see them - A new iPhone finds the backup and offers it on first launch - Save a backup file any time, free, and keep it where you like - Premium your way: a subscription or a one-time unlock removes ads, lifts limits and lets you restore from iCloud Drive or a backup file whenever you like - Japandi-inspired design: calm, warm and distraction-free Whether you're keeping a first starter alive or dialling in your hundredth sourdough pizza, The Bake Log is the offline baking journal and sourdough app that grows with you.
