Yeasta: Sourdough Tracker

Yeasta is the sourdough companion that knows what's next.

Whether you're nurturing your first culture or juggling four starters at once, Yeasta keeps every feeding, every bake, and every outcome in one place. Open the app and it tells you the one thing that matters most right now.

KNOW WHAT'S NEXT
Smart Today watches your starters and your bakes. Overdue feeding, starter nearing its peak, bake halfway through bulk — the Home screen surfaces the one thing you should do next, the moment you open the app. A running bake shows its time left in big numbers, every starter gets a bar showing how close it is to its peak, and a Coming up list lines up your next feedings and bake steps.

BAKE WITH A GUIDE
Start a guided bake from any recipe and Yeasta walks you through it step by step. Live timers tick on your lock screen so you can step away and never lose your place. Mark steps complete, add notes, log the outcome when the loaf comes out.

CARE FOR EVERY STARTER
Track rhythm, ratios, and readiness across every jar you keep. Log feedings in seconds. See which starters are peaking, which are napping, which need feeding right now. Edit or delete any log entry whenever you need to.

RECIPES THAT TRAVEL WITH YOU
Browse a growing sourdough library: classic country loaves, same-day breads, focaccia, pizza dough, and more. Scale any recipe by tap. Save your favorites. Start a guided session when you're ready.

MATH MADE FOR BAKERS
Built-in tools handle the math you used to do on the back of a napkin: hydration, baker's percentages, salt, levain ratios, starter scheduling, and temperature conversion.

PRO TOOLS FOR SERIOUS BAKERS
Five dedicated pro tools take your baking further:
- Levain Builder: calculate exact flour, water, and starter ratios for any levain, with optional two-flour blending
- What Can I Bake?: find recipes that match your starter, available time, and mood - split into "make now" and "plan ahead"
- Fridge Starter Planner: generate a personalized fridge-to-bake timeline with automatic milestone reminders
- Starter Revival: symptom-based revival plans with a day-by-day feeding schedule and notifications
- Starter Smell Guide: diagnose your starter's health from eight common smell symptoms in seconds

EVERY BAKE, REMEMBERED
The Journal keeps every feeding, every bake, every outcome. Feedings read like a baker's log, and bakes of the same recipe line up side by side so you can see what changed. Search by name, or just scroll and remember that perfect loaf from last March. Want the raw numbers? Export the whole journal to one CSV file, free.
