A companion for making a sourdough loaf, making and caring for your starter Look after your sourdough starter, and get alerts when it's time to feed it. Track whether you keep it on the counter or in the fridge (when chilly, your starter needs feeding less often). Automatically work out the ratios of flour, water, starter and salt when making a new loaf. Use the handy timers and step trackers as you go through the process of mixing and baking a sourdough loaf from scratch. Two Widgets are available: The first reminds you you right on the home screen when it's time to feed your starter. The second keeps track of your making and baking timers, so you never miss a step!
