Know the moment your starter peaks. Feed on time, plan bakes backwards, and never lose a starter again. No ads, no weekly subscription.
Is your starter ready — or still asleep? Barm takes the guesswork out of sourdough.
Barm watches your starter for you. Log a feed in two taps, mark the rise with a rubber-band line, and Barm learns how fast your starter grows in your kitchen. It predicts the peak and tells you when it's ready to bake.
PEAK PREDICTION
• A live rise curve for every starter
• Countdown to peak, adjusted for your room temperature
• A notification when it's time to mix — not a random timer
EFFORTLESS FEEDING LOG
• Log feeds, ratios (1:1:1, 1:5:5…), flour, water and temperature
• Smart reminders that reset when you feed early
• Several starters, each with its own photo timeline
• Fridge and vacation mode with a revival plan
CALCULATORS THAT SPEAK BAKER
• Hydration and baker's percentage calculator
• Feeding calculator for any ratio or target amount
• Desired dough temperature: the right water temperature, every time
• Scale any recipe by loaves or final dough weight
BAKE PLANNER
• Choose when you want bread out of the oven; Barm works backwards to the feed, levain, bulk, shape and bake
• Every step on your Lock Screen with Live Activities
• Widgets that show your starter at a glance
A JOURNAL YOU'LL LOVE
• Crumb photos, notes and ratings for every loaf
• See what changed between your best and worst bakes
• Discard tracker with ideas to use it up
