Layered
Sourdough apps do one of three jobs. Some keep a record of your starter and bakes. Some look at a photo and tell you what went wrong. Some hand you recipes. Which one you want depends on what you are missing.
Side by side
| App | Built for | What you log | How you pay |
|---|---|---|---|
| Fermento | people who ferment more than one thing: sourdough, kombucha, pickles, cheese, charcuterie | pH, salt, weight, temperature, photos and notes on a timeline, with reminders for feeds, flips and checks | free to download, with a paid plan for some features, such as HACCP plans |
| Loaflo | sourdough bakers who want AI feedback on their loaves | starter feedings, hydration and growth | a weekly, monthly or yearly subscription |
| Kneady | home bakers who want bread recipes to follow | saved favourite recipes | a free plan, with the rest on a Kneady Pro subscription: monthly, quarterly or annual |
A journal: Fermento
Fermento is a fermentation journal for iPhone and iPad. It keeps pickles, sourdough, cheese, kombucha and charcuterie on schedule with timelines and reminders, and logs pH, salt, weight, photos and notes in one place.
For sourdough that means a record for the starter, with its feeds, health and family tree, and a timeline for each bake with hydration, dough temperature, photos and taste notes. The sourdough timeline shows what a bake looks like step by step.
Loaflo
Loaflo is a sourdough app with AI at its centre. You photograph a loaf or starter for feedback on crust and crumb, follow recipes, log starter feedings and hydration, use calculators, and chat with a baking assistant called Mr. Crumb.
Fermento is one journal for everything you ferment, with timelines, readings and reminders for each batch. Loaflo is a sourdough app built around AI photo analysis. See Fermento vs Loaflo.
Kneady
Kneady is a bread recipe app. Its listing describes a library of recipes from professional bakers with step-by-step guidance, timers for rising, kneading and baking, a Baking Mode, saved favourites and a community for sharing bakes.
Fermento is a journal: each bake gets a timeline, readings and taste notes, and the starter keeps its own record. Kneady is a library of bread recipes with timers. See Fermento vs Kneady.
How to choose
Start from what is in your kitchen. Most people who ferment end up with more than one thing going: a starter, a crock, a few bottles. One journal that keeps all of them on schedule, with the readings beside each batch, saves keeping an app for each. That is Fermento.
If you bake once a week from the same recipe, what improves the next loaf is knowing what you did last time: the ratio you fed, how long the bulk ferment ran, how warm the kitchen was. That is a journal's job.
More comparisons
We make Fermento. What we say about the other apps comes from their own pages, read on 11 November 2026: Loaflo on the App Store, Kneady on the App Store, kneady.io, and each comparison page lists its sources. Each name belongs to its owner, and Fermento is not affiliated with any of them.

Questions
What is the best app for tracking a sourdough starter?
Fermento, if you want the starter's feeds, health and family tree next to the loaves made from it. It also tracks the other ferments in your kitchen.
Is there an app that tracks sourdough and other ferments together?
Yes. Fermento keeps sourdough, kombucha, pickles, cheese and charcuterie in one journal, each batch with its own timeline and readings.
Do I need a sourdough app at all?
A notebook works for one loaf a week. An app earns its place when you want reminders for feeds, readings you can compare between bakes, and a record that survives a flour spill.
