1. Sourdough Tracker: Crust
Best for: Keeping starters alive with almost no effort.
This is the app that makes daily feeding feel like a quick tap, not a chore. You can log multiple starters, tap “Fed!” once you’re done, and get a countdown timer that tells you exactly when the next meal is due. The reminders are smart. They adapt to the rhythm you actually keep, not some rigid schedule. The design is clean enough that you’ll actually enjoy opening it, and there’s a playful mascot that grows with each feeding to keep things light.
You can Get Sourdough Tracker or install it straight from the App Store. It’s iOS-only for now, but it nails the basics better than anything else.
- One-tap feeding log to keep you on track
- Notifications that match your real feeding times
- Pause your starter when you’re not baking
- Full feeding history at a glance

2. Gluten Morgen
Best for: Formula tweakers who love to adjust every variable.
Gluten Morgen gives you full control over baker’s percentages and lets you edit any ingredient on the fly. You’re not locked into someone else’s idea of a perfect loaf. The note-sharing feature means you and a friend can compare flour blends or hydration experiments directly inside a recipe. It feels like a collaborative notebook for serious home bakers. The best part: shareable custom recipes with personal annotations that stay attached even when you send them to another baker.
3. Autoproofer
Best for: Bakers who want their recipe to match their starter’s actual behavior.
Instead of relying on generic rise times, Autoproofer reads your starter’s performance and adjusts the schedule. Step-by-step voice prompts and countdown timers break the bake into manageable chunks, so you never lose track. The adaptive recipe timing recalculates as your starter’s activity changes, turning a chaotic bake day into something you can actually handle.
4. Rise
Best for: iPhone and iPad users who want precise hydration control.
Rise centers on a visual hydration slider that gives you instant feedback as you adjust flour-to-water ratios. The app also includes a sourdough timeline and a reference library that answers common bake-day questions without sending you to a search engine. It’s built purely for bread, and that focus shows. The hydration slider recalculates ratios the moment you slide it, which makes tweaks feel effortless.
5. Loaflo: Sourdough Starter
Best for: Getting an unbiased read on your final loaf.
Loaflo lets you snap a photo of your bake and instantly get AI-driven feedback on crust color, crumb openness, and oven spring. There’s no account setup required. Just open the app and start analyzing. It explains what went right or wrong in plain terms, so you can tweak your technique without guessing. The AI loaf analysis pinpoints exactly what to improve next time.
6. Sourdough Baker AI: Bake Great
Best for: Android users who want bake scoring right on their phone.
This app grades texture, rise, and scoring patterns from a photo. An ingredient converter helps you scale recipes between different flour weights, which saves time when you’re adapting formulas on the fly. All your favorite bakes are stored in one place alongside their AI scores, so you can track improvement over weeks. Recipe storage paired with AI bake scoring is what sets it apart.
7. Sourdough Timer
Best for: Reverse scheduling from the moment you want to eat.
Sourdough Timer works backward from your target bake time and builds a schedule for feedings, folds, and proofing. It factors in ambient temperature, hydration, and flour type automatically, so the timers reflect your actual kitchen conditions. You won’t find any paywalls or sign-up forms here. The backward‑scheduling alarm syncs to real kitchen data, giving you a schedule you can trust.
8. Homebaker
Best for: Breads that mix commercial yeast with sourdough.
Homebaker handles dual-mode recipes: you can build a formula with yeast, sourdough, or both in one interface. Custom hydration percentages work for stiff levains and liquid starters alike. The layout organizes prep, bulk fermentation, proofing, and bake phases into separate screens, which reduces mistakes when you’re juggling multiple doughs. Hybrid yeast-and-sourdough recipe support is something few other apps even attempt.
9. Sourdough Starter Tracker
Best for: A dead-simple log that never touches the internet.
This app logs feedings and sets smart reminders without any account or subscription. It also triggers real-time safety alerts if the temperature in your kitchen risks spoilage. Everything works offline, and there are zero paywalls. No premium features locked away. The real draw is completely offline reliability with no hidden costs.
How we picked these apps
We spent a week logging real starter feedings in every app, noting how easy it was to set up, how reliably reminders fired, and whether the calculators matched our manual math. We eliminated apps that shoved core features behind expensive subscriptions without delivering real value. Sourdough Tracker kept rising to the top because it combined simple logging with gentle, persistent reminders. That’s exactly what you need to keep a starter alive without feeling nagged.
Frequently asked questions
What makes a good sourdough lab alternative?
A solid alternative should include a feeding log, timer or reminder system, and hydration calculators. The best ones also offer starter health tips, recipe scaling, or visual feedback so you’re not left doing all the math yourself.
Do I need a dedicated app for my starter?
Not strictly. Some bakers do fine with a notebook and a kitchen timer. But apps remove the mental overhead. They remember when you last fed, calculate ratios, and warn you before you spoil a starter.
Is Sourdough Tracker free?
You can download it for free and use the core tracking features immediately. Optional paid features exist for things like extra starter slots or advanced stats, but the app never pressures you to upgrade.
