Quick comparison table

1. Sourdough Tracker: Crust

Best for: bakers who want reliable reminders, not another tool to learn.

This is our top pick sourdough starter tracker because it strips away everything that gets in the way. You open the app, tap “Fed!” once, and it resets the countdown. No charts, no AI, no clutter. Just a clean feeding log and a clear timer telling you exactly when to feed next.

Push reminders are where it truly shines. They sync to your starter’s actual rhythm, not a generic 12-hour schedule. You’ll never wander into the kitchen and find a neglected, hooch-covered jar again. The interface stays calm and simple: see your full feeding history at a glance, pause starters when you’re not baking, and watch the little mascot grow with each feeding. It’s built for reliability without a learning curve.

Standout feature: guilt-eliminating notifications that adapt to your real feeding times, so your starter stays alive on your terms.

2. Loaflo: Sourdough Starter

Best for: visual learners who want a second opinion from a photo.

Snap a picture of your starter or finished loaf, and Loaflo serves up AI-driven feedback on what it sees. Alongside feeding logs and hydration tracking, it helps you diagnose sluggish rises before bake day. The biggest draw is the photo-based crumb and starter analysis. A single image can suggest tweaks like adjusting water or proofing time.

3. Sourdough Forge

Best for: multi-starter bakers who want everything in one place.

Sourdough Forge handles multiple starters, detailed bake planning, and journaling without switching apps. Its AI coaching learns from your notes to give personalised improvement tips over time. The highlight is the integrated bake planner: it marries your starter’s feeding schedule with recipe timelines so you never lose track of when to autolyse or shape.

4. Yeasta

Best for: anyone who wants a tracker that stays completely offline.

Yeasta is a lightweight, privacy-first sourdough starter tracker. All your data stays on your device. No account, no cloud sync. It handles multiple starters, feeding logs, and trend spotting with dashboard clarity. The neat part is local-only storage that gives you the same clean experience as cloud apps, minus any data trade-off.

5. SourFriend

Best for: bakers who want a health check, not just a timer.

SourFriend watches your starter’s fermentation progress and interprets rise and activity levels. Instead of just counting hours, it sends smart nudges when your starter looks weak or overly ripe. Those proactive health alerts help you catch a failing starter before you’ve mixed dough, preventing bake-day disappointments.

6. Starter - Sourdough Tracker

Best for: Android newcomers who hate wasting discard.

This beginner-friendly Android app sends straightforward feeding reminders and helps you track multiple starters. The built-in discard recipe library is the real draw. Rather than pouring excess down the drain, you can flip through recipes for pancakes, crackers, and more, turning a pain point into something useful without leaving the app.

7. Sourdough Baker AI: Bake Great

Best for: Android bakers who want AI to judge their loaf, not just their starter.

This goes beyond simple tracking. The app analyses bread photos to perfect your crumb, converts ingredients between grams and volume, and stashes your favourite recipes. The killer feature is real-time AI bread assessment: snap a loaf picture and get feedback on oven spring, structure, and colour, so you can iterate faster bake by bake.

8. Sour & Dough - Bread Baking

Best for: quick dough math on Android without any fluff.

Enter your flour weight, and this calculator instantly gives you water, salt, and levain measurements. On-screen checkboxes make sure you’ve added every ingredient during mixing. The flour-first calculator uses baker’s percentages, so you can play with custom hydration and watch all other ingredients fall into place automatically.

9. Sourdo - Sourdough Crumb Reads

Best for: bakers obsessing over crumb structure and fermentation quality.

Sourdo does one thing: snap a picture of a sourdough slice and get instant AI feedback on openness, evenness, and fermentation. It’s not a feeding tracker, so it pairs perfectly with a dedicated app. The clever bit is fermentation diagnosis from a single photo. It helps you dial in proofing times batch after batch.

10. breadly - Sourdough Scheduler

Best for: planners who manage multi-day bakes and cold proofs.

Breadly marries starter feeds with dough resting periods inside a clean visual timeline. You map every step: levain build, autolyse, folds, bulk, shape, cold proof, and bake. It keeps you on track without paper notes. The best part is a scannable timeline that shows exactly where you are, especially helpful for overnight schedules.

How we picked these apps

We looked specifically at apps that solve the core “sourdough starter tracker” need without burying useful features under clutter. We tested feeding-entry speed, reminder reliability, and how well each app worked across iOS and Android. Privacy mattered: we valued offline tools that keep data local. We included AI features only where they meaningfully improved results, not as gimmicks. Apps that were mostly recipe databases with weak starter tracking didn’t make the cut. Every pick here addresses a real pain point like missed feedings, hydration guesswork, or schedule chaos.

Frequently asked questions

What exactly does a sourdough starter tracker do?

It logs feedings, counts down to the next feeding, and sends reminders. Many also track hydration ratios and starter age so you always know the health of your culture at a glance.

Can I just use a notes app or timer instead?

You can, but a dedicated app removes the mental load. It remembers your last feed, adjusts reminder timing automatically, and often includes handy extras like discard recipes that a plain timer won’t offer.

Are these apps free?

Most offer a free tier or a one-time purchase. Some rely on subscriptions for advanced AI features, while privacy-first apps like Yeasta are paid upfront to avoid data collection. Several Android picks are free with optional upgrades.

Do I need a separate iOS and Android app?

Core tracking works similarly on both platforms. The list splits Android and iOS picks where one app shines brighter, but if you swap ecosystems, you’ll find a solid sourdough starter tracker on either side.

The verdict

Sourdough Tracker: Crust is the most reliable, distraction-free way to stop killing your starter. One-tap logging, perfectly timed reminders, and a dead-simple interface are the formula for consistent bakes. It handles the remembering so you handle the baking.
