Choosing a sourdough starter app

Search for a sourdough app and you will find dozens: starter trackers, timers, calculators, recipe managers, and a few that try to do everything. We make one of them (Banneton, this site’s app), so read this with that in mind. But the checklist below is genuinely how we would shop, and it applies to every app in the category, including ours.

What a starter app actually has to do

The daily job is small and unforgiving: know when each starter was fed, show whether it is fed, due, or overdue at a glance, and remind you at the right moment. Almost everything else is garnish. When you evaluate an app, test that loop first:

Log a feed in one tap. If feeding takes a form with five fields, you will stop logging by week two. Detail should be optional, not required.
Reminders that match your rhythm. Every 12 hours, daily, every 2 or 3 days: starters run on different clocks, and a fridge-dormant starter should be quiet. An app that nags a resting starter teaches you to ignore it.
A visible state, not a buried log. Fed, due, or overdue should be readable from across the room, ideally from a widget without opening the app at all.

The math should be a real engine

Hydration, baker’s percentages, feed ratios, and fermentation timing are one connected system, not four separate novelty calculators. Check whether the app can scale a formula to a loaf count, account for the flour and water inside the starter when it reports hydration, and adjust fermentation time to dough temperature. If you want to test the category standard, the free calculators on this site show the numbers a real engine should produce.

Questions worth asking before you commit

Does it need an account? A starter tracker holds nothing that requires a login. An account requirement usually means your data lives on someone’s server, and the app dies when the server does.
Does it work offline? Kitchens have flour in the air and spotty Wi-Fi. Feeding, math, and schedules should work in airplane mode.
Where do the photos go? Bake photos are personal. On-device storage with your own iCloud sync is the privacy-safe default; check the App Privacy label on the store listing.
What does it cost, honestly? Subscriptions are fine when they are honest about what is free and what is not. A one-time lifetime option is a good sign the developer is not counting on you forgetting to cancel.
Is it maintained? Look at the version history. A starter app you will use daily for years should not have been last updated two of them ago.

Where Banneton lands

Since you are on our site: Banneton is built around exactly this checklist. One-tap feeds with state at a glance, including a Feed button right on the home-screen widget and a watch-face complication, so logging never requires opening the app. Reminders tuned to each starter’s interval (and silenced for dormant ones), a real shared engine behind the math and the temperature-aware bake schedule, no accounts, fully offline, photos on your device, and pricing with a free core, a subscription, and a lifetime purchase. If a different app fits your bake better, use that one; the checklist still holds.

If you would rather just read: the complete sourdough starter guide, the sourdough troubleshooting index, and the free calculators need no app at all.
