How we picked: we read each app’s own App Store description for how it tracks a starter, whether it reminds you to feed, whether it guides a bake and what it does with a photo. We do not quote prices; check them in the store for your country.
A coach for your starter
Sourdoughy works like a pocket sourdough coach: you take a photo of your starter and its AI tells you what stage it is in, how healthy it looks, whether it is ready to bake, what to do next and how to fix common problems. You build a feeding schedule that fits your kitchen, with reminders to feed, and learn the craft with step-by-step tutorials, from creating a starter to stretch and fold, shaping, scoring and reading fermentation. Recipes for boules, seeded batards and sandwich loaves come with ingredients and exact timings, and a troubleshooting section covers dense crumb, flat loaves and sluggish starters. The app is in English and Spanish, and a premium subscription unlocks unlimited AI check-ins, all tutorials and the full recipe library.
Feeding logs and reminders
Loaflo logs feedings, tracks hydration and monitors your starter’s growth, and its AI gives feedback on a photo of your starter or loaf, crust and crumb included. It adds recipes with explanations, calculators to forecast rise, adjust ratios and convert units, and a baking assistant to chat with, all without signing up. Sourdough Starter Tracker keeps to the basics on purpose: feeding logs, health tracking, reminders and pop-up safety alerts for an unusual smell, overheating risk, no visible activity or a beginner emergency, plus a checklist to run before baking. It works offline with no account, and deeper health tips across temperature, hydration, smell, rise, bubbles and feeding interval are in its premium tier.
Several starters, guided bakes and crumb checks
Yeasta is built for keeping more than one starter: it tracks rhythm, ratios and readiness across every jar, and its home screen surfaces the one thing to do next, such as an overdue feeding or a starter nearing its peak. You can start a guided bake from any recipe, with live timers on the lock screen, notes on each step and a record of how the loaf came out. Sourdo looks at the result: snap a photo of a slice and its AI evaluates the crumb for openness, evenness and fermentation quality. It also analyses your starter for strength and activity and has an AI chat for troubleshooting.
