Sourflow is a sourdough baking companion for home bakers who want to stop guessing and start understanding their bakes. Every session you log teaches you something about the next one. Try Sourflow free for a month. Track every phase, log every bake, and finally understand what makes your sourdough work. No guesswork. No notebooks. Not a recipe app. A baking journal that happens to hold recipes — built around the data that turns inconsistent results into repeatable ones. Bake Timer Step through up to 8 phases — autolyse, bulk, shape, proof, bake — each individually timed. Log room, water and dough temperatures per session, track stretch-and-folds, and get a bulk fermentation estimate based on your temperatures and your own baking history. A Live Activity widget keeps your current phase visible on the lock screen and Dynamic Island. Levain Tracker Log every feeding with ratio, flour type and temperature. Track your starter's rise state, get peak predictions based on your feeding history, and set reminders so you never miss the window again. Recipes & Guided Baking Save your own formulas by weight or baker's percentage with automatic hydration calculation. Follow any recipe in step-by-step mode — each stage with its own built-in timer, so you never need to switch apps mid-bake. Session Logbook Every completed bake is saved with phase timings, temperatures, linked recipe, notes, fold count, crumb photo and grading. Compare sessions side by side to understand what actually changed. Analytics See how dough temperature affects fermentation duration, track your bake frequency over time, and watch your own patterns emerge the more you bake. Your bakes deserve better than a notebook. Start tracking with Sourflow. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
