Best of
A starter is a living thing on a schedule, and the tool you track it with decides whether your next loaf starts from notes or from memory. Here's how the real options compare - apps, spreadsheets, notes and plain paper.

Search "best sourdough app" and you get a wall of opinions but no honest comparison. The truth is that the best tool isn't always an app: it's whatever reliably captures three things at every feed - when you fed, how high it rose, and how it smelled - and shows you the pattern over days. A camera roll captures the photo but loses the timeline. A notes app captures words but not the rise curve. A spreadsheet captures numbers but won't remind you. Below is each option, what it's genuinely good at, and where it falls down.
If you just want the short answer: a dedicated tracker wins for anyone who bakes more than once in a while, because it's the only option that turns each feed into a chart and reminds you before the starter peaks. Everything else is a workaround that loses one of the three signals.
Tools we'd recommend for home bakers looking at sourdough tracking apps.
The purpose-built starter journal
A free app built only for this: log each feed with a photo, rise height and smell, and it draws the pattern, predicts the next peak and reminds you to feed. It reads the photos to estimate rise, works offline, and keeps the whole journal even when you share a starter. It's the option that captures all three signals without any setup.
Anyone who bakes regularly and wants the starter to stop being guesswork.
The closest direct alternative: a paid app aimed at the same job. If you specifically want a competitor view, the head-to-head with Loaflo covers pricing, the free tier and where each app fits.
Bakers comparing the two dedicated apps before they commit.
Apple Notes, Notion or Google Keep can hold feed notes and photos in one note. It's free and familiar, but it never turns the entries into a rise curve or reminds you to feed. The sourdough app vs notes app comparison shows exactly where the manual work piles up.
Casual bakers who already live in one notes app and bake rarely.
Snapping the jar is the habit most bakers start with, and the photos are genuinely useful. The problem is the camera roll buries them among everything else and keeps no rise height, smell or feed time. The camera roll comparison explains why photos alone don't add up to a record.
A backup to any real tracker, not a record on its own.
A dedicated paper notebook is the analog classic and many bakers love it. It's offline and pleasant, but it can't chart a trend, hold a photo or remind you, and a floury kitchen is hard on paper. The paper notebook comparison weighs the trade honestly.
Bakers who want a screen-free ritual and bake occasionally.
Strip away the marketing and a starter tracker has one job: make the invisible pattern visible. A starter rises and falls on a schedule set by temperature, feed ratio and age, and none of that is obvious in the moment. The tools that help capture rise height, feed time and smell at each feed, then show the trend, so you can see a starter slowing down before it stalls and bake at the actual peak. The ones that don't help capture only a fragment - a photo, a sentence, a number - and leave you to reconstruct the rest from memory.
If you want the reasoning in depth, why journaling a starter matters makes the full case, and baking around your starter shows how a tracked starter changes your schedule rather than the other way round.
Every method trades effort against insight. A spreadsheet gives you numbers and total control but no reminders and no photos, and you build every formula yourself. A notes app or camera roll costs nothing and needs no setup, but neither turns entries into a curve. A dedicated app does the charting, prediction and reminding for you, at the cost of being one more app. For a once-a-month baker any of these is fine; the more often you bake, the more the automatic pattern-spotting of a real tracker pays for itself.
We judged each option against the three signals a starter actually gives - feed timing, rise height and smell - plus whether it reminds you, works offline and survives a floury kitchen. We build Sourdough Tracker, so we've listed it first and been explicit about it; the four comparisons it links to are written to be honest about where the simpler options genuinely win, because for a casual baker they sometimes do.
