Photos of jars at peak are the hidden journal most bakers keep. Here's why moving them somewhere else makes the practice click.

Photos of starters at peak are the most accurate journal you already keep - they're just not labelled and not searchable. Sourdough Tracker doesn't replace your camera; it just gives each photo a home next to the entry it belongs to. Six months in, your camera roll has 200 photos of jars and you can't tell which feed each one was; the journal has 200 photos attached to feeds, with rise % and ambient temp next to each.
Free plan, no credit card. We host in Germany. You can export and delete everything self-serve.
