Sourdough and Fermentation Process Tracker That Learns From Your Baking History
Home sourdough bakers track dozens of variables (ambient temperature, humidity, flour type, hydration, timing) across multi-day processes but have no tool that learns from their specific environment and past bakes. Existing apps offer timers and calculators but don't build a model of YOUR kitchen and YOUR starter. Hardware solutions like Crustello require $100+ sensors. Bakers resort to spreadsheets and notebooks.
Start as a structured baking log (temperature, timing, hydration, outcome photo) and add the prediction layer after you have 20+ bakes from each user. The sourdough community is fanatical about data and will manually log everything if the app makes the data useful. The MVP is literally a spreadsheet with a nicer UI and outcome correlation charts.

Timer apps handle individual bakes but don't learn across bakes. Hardware solutions add sensing but cost $100+. The missing product is a software-only baking journal that correlates variables across your bake history and says last time your kitchen was this temperature, you got best results with 4-hour bulk ferment.
