Levain keeps your sourdough starters alive and thriving, and actually shows you how they're doing. Set up your starter, tap "Fed!" when you feed it, and get gentle reminders when the next feed is due. No more dead starters, no more guessing when you last fed them. A STARTER THAT COMES ALIVE Watch your starter rise and fall right in the app, in sync with its real feeding cycle: climbing after a feed, doming at its peak when it's the perfect time to bake, and sinking when it's getting hungry. One glance tells you exactly where it's at. NEVER MISS A FEED Reliable reminders keep firing even if you don't open the app for days, with gentle nudges if your starter's been waiting. A Home-screen widget shows your next feed at a glance. EVERYTHING IN ONE PLACE - Multiple starters with names, photos and custom schedules - One-tap feeding with a countdown to the next feed - Feeding history and a photo album for each starter - Pause for the fridge when you're not baking - Feeding-ratio helper and a peak timer for the perfect bake window - A bake journal to log your loaves with crumb photos and ratings - Streaks and stats to keep you consistent - A shareable card to show off your starter and your bakes Your starters sync privately through your own iCloud, never our servers, so they follow you to a new device. No account. Set it up in 30 seconds and let Levain keep your starters happy. Levain Pro unlocks every feature.
