Barm

Barm is a fast, fully offline log for your sourdough starter — built for bakers who want data, not a diary. Track every feeding with one tap, watch your rise trend as a live chart, and time the float test right from your pocket, all without opening a spreadsheet or writing a paragraph.

Most sourdough trackers turn feeding your starter into a journaling chore — photos, mood notes, endless taps. Barm skips the fuss: pick a hydration ratio, log the grams, done. A built-in ratio calculator works out flour and water for you, and the float test timer tells you exactly how long your starter took to peak.

Everything lives on your device. No account, no cloud sync, no ads — your starter's feeding history and rise data never leave your phone.

Included forever for a single starter: unlimited feed logging, the rise chart, and the float test timer. Upgrade to Pro for unlimited starters, CSV export, custom feeding reminders, and rise-time stats — a one-time purchase, no subscription.
