Quick comparison

1. Sourdough Tracker: Crust

Best for: Sourdough bakers who want a starter they’ll never neglect again.

Most starter apps overcomplicate things. The real pain point is simple: you forget to feed your starter, it dies, and you feel guilty. Sourdough Tracker fixes that with a clean iOS interface and a one-tap feeding routine. Tap “Fed!” and the countdown resets. Push notifications then nudge you before the next feed, so you never have to guess when you last did it. That loop turns starter maintenance into a 30-second daily ritual instead of another chore.

• Add multiple starters with custom names and icons
• One-tap feeding marks your starter as fed and resets the timer
• Countdown shows exactly when the next feeding is due
• Gentle push notifications that remind without guilt
• Full feeding history at a glance; pause starters when you’re not baking
• Cute mascot that grows with every feed

2. FermentHero

Best for: Home fermenters who juggle sourdough, kombucha, and kimchi under one roof.

FermentHero comes loaded with hundreds of professional recipes and a visual timeline that shows each ferment’s progress at a glance. Automatic reminders keep multi-batch schedules from colliding. This is especially handy when you’ve got a kimchi ferment, a sourdough starter, and a kombucha brew all vying for attention. It’s a solid pick if you want guidance beyond a single ferment type, though the recipe depth means you’ll spend a little more time exploring before you hit your stride.

3. Fermentation Journal: Fermento

Best for: Apple users who want a polished, all-in-one journal for pickles, sourdough, and charcuterie.

Fermento feels like a dedicated notebook rebuilt for mobile. Smart timelines adapt to your ferment type, calculators handle brine percentages and salt ratios without a separate spreadsheet, and the layout stays clean whether you’re a beginner or a pro. Every detail, from pH readings and photos to tasting notes, lives in one place, so you can revisit a successful batch of half-sours or a salami project months later. It’s iOS-only, but the journaling experience is worth the price if you’re serious about record-keeping.

4. FermentMe

Best for: Tracking countless ferments without any fuss.

Built by a home fermenter, FermentMe focuses on the essentials: log ingredients, instructions, and photos for nearly any ferment you can think of. Push notifications ping when it’s time to taste or check a batch, so you’re not constantly peeking under lids. It handles everything from sauerkraut to hot sauce with the same straightforward log, making it a trusty sidekick when you’d rather spend time fermenting than fiddling with an app.

5. Loaflo: Sourdough Starter

Best for: Bakers who want AI-powered feedback on every loaf.

Loaflo tracks your starter feedings, hydration, and schedule, then adds something unique: photo analysis that critiques your baked loaves’ crust and crumb. Snap a picture, and the app gives personalized pointers, like a baking coach that tells you why your ear split or your crumb turned gummy. Starter tracking alone is solid, but that instant visual feedback can accelerate your improvement faster than trial and error alone. It needs internet for AI features, though logging works offline.

6. Kombu Time

Best for: Kombucha brewers who want simple second-fermentation alerts and nothing else.

Kombu Time strips kombucha tracking down to the one thing that trips up most brewers: F2 timing. Set your batch and the app notifies you exactly when to start or end secondary fermentation. There’s no recipe catalog, no fluff. Just clear alerts and minimal logs. It’s a great pick if you already know your process and just want a reliable timer that doesn’t distract you with features you’ll never open.

7. Kombucha Brew Tracker

Best for: Android users who need offline kombucha tracking across multiple batches.

Kombucha Brew Tracker runs entirely offline, so you can manage brewing schedules in the garage or basement without hunting for WiFi. Smart countdown timers help you coordinate simultaneous first and second fermentations, and batch logging keeps every brew’s details separate. It won’t win design awards, but the offline reliability and multi-batch chops make it ideal for serious homebrewers who prefer a set-and-forget approach.

8. Brewfather

Best for: Precision-minded homebrewers making beer, mead, or cider.

Brewfather goes deep: recipe design tools, water chemistry calculators, fermentation tracking graphs, and a community recipe library with thousands of shared formulas. You can dial in every gravity point and IBU, then track the batch from brew day through packaging. It’s a powerhouse for anyone who treats brewing like a science, though the sheer number of options can feel heavy if you’re just dipping your toes into beer fermentation. The free tier is generous, but the real depth lives behind a subscription.

9. HakkoBako

Best for: Curious fermenters chasing unusual projects like lacto-fermented hot sauce.

HakkoBako leans into the creative side of home fermentation. Guided projects walk you through building a sourdough starter from scratch or crafting quick pickles with fun ingredients, while tastemarks let you record sensory snapshots alongside time-lapse photos and audio notes. It’s less about rigid logs and more about the story of your ferment, perfect if you care as much about the experience as the final pH. First-timers will appreciate the friendly prompts, and veterans can still find fresh inspiration.

How we picked these apps

We tested each app with real ferments, sourdough starters, kombucha, beer, and more, to see which ones actually fit a home fermentation routine. Clear reminders and reliable timers were non-negotiable; an app that missed a feed alert didn’t make the list. We favored apps with clutter-free logging and genuine user reviews over abandoned downloads. We also made sure to cover different niches (bread, beverages, vegetables, meat) and both iOS and Android where possible. Sourdough Tracker: Crust stood out because it solves the single most painful daily problem, forgetting to feed a starter, with almost no effort, and its active development shows the team understands what home fermenters actually need.

Frequently asked questions

Can one app handle all types of home fermentation?

Few apps cover every ferment well; you’ll get better results pairing the tool to the project. FermentHero and Fermento handle a wider range, while Sourdough Tracker focuses exclusively on sourdough, and it does that best.

Do fermentation apps work offline?

Most logging and timer features work without internet. Kombucha Brew Tracker is built fully offline, while apps like Loaflo need occasional connectivity for AI photo analysis and cloud sync. Timers still fire even if you’re in a dead zone.

Are fermentation apps beginner-friendly?

Yes, many include guided steps and sensible defaults. Sourdough Tracker’s one-tap simplicity is ideal for new bakers, and HakkoBako’s creative prompts make first-time ferments feel less daunting. Always check an app’s onboarding flow. If it feels clear in the first two minutes, it’s likely a keeper.

The verdict

Sourdough Tracker: Crust is the best home fermentation app for keeping a sourdough starter alive without stress. Its straightforward feeding log, well-timed reminders, and guilt-free approach turn starter care into a habit you’ll actually stick with. While other apps excel for kombucha or beer, none make daily starter maintenance this effortless. Get Sourdough Tracker and start building a healthier, happier starter today.
