Don't be afraid of starting your Sourdough journey! Try Yeasta's plan mode for the best results | Now offering a trial for 3 days
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.
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 grouped by day. Filter by type, search by name, or just scroll and remember that perfect loaf from last March.

I am new to sourdough, I’ve tried creating a starter to about 7 or more times. I’m seeing some positive progress and part of that is thanks to Yeasta. Being able to keep track is very helpful, however, I would like to be able to make adjustments to the progress time or starter itself without having to reset the entire data if a wrong input is made. The inability to delete a single entry or to edit an entry is frustrating. That’s the reason for the 4star. If that feature could be added then it’s a five star for me. It’s an overall good app. Thank you for providing this resource.
Developer Response
Hello Kala,The editing feature is now live!Original response:I appreciate you taking the time and reviewing my app! An option to modify and change existing logs will drop as an update within the next few days, and hopefully it’ll help you continue your sourdough journey!Soon enough I’ll also have a recipe repository for recipes you can try and make with your starters, as well as some autolyze timers and helpers to schedule everything within the app. Thanks for you continued support, hope your starters flourish!Mor
Great start!

Such a cute app to help people get familiar with the process. I love the reminders to feed my starter based on my schedule and the ability to keep track of multiple starters!My only thought is that I would love to be able to add my own recipes to my profile. They don’t need to be shared to all users, I just want a spot to add recipes I already use and enjoy.
Developer Response
Quick edit: you should be able to add your own recipes now. Enjoy!Original response: Hi Jade! Thank you for your candid review. I will iterate on your idea for custom recipes and add that to the next update, hopefully. Along with the current selection of recipes, I’m working on adding a lot more recipes now for rye and artisanal breads from a local baker I met. I hope it will allow you to elevate your baking! Every recipe is first self tested by me before I add it in, so some of them take a short while.
Nice app, need small update
Ofir_K
Good and simple app, but Please add the following simple features:1) edit/delete logs 2) option to log more then 1 type of flour to the log, for example 50 gr rey and 50 grams spelt This changes can make the app a 5 stars one.Ty
Developer Response
Hi Ofir, Editing your logs is now available - make sure to update to 1.3.1. Selecting different flour types will be included in the next update during the weekend.Original response:I really appreciate your feedback and input. Deleting logs is coming in the next update already, and splitting the flour type is something I haven’t considered as an option, so I truly appreciate this input. I will implement a solution to let you choose between one type or multiple types. Have a wonderful day!Mor

Purchased the Pro Annual Subscription plan and I am blocked from the upgraded features. I clicked Restore Purchase and it says none found. I want a refund.
