SourdoughKeeper

Never kill another starter.

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

You opened the fridge and your starter was gray. The hooch layer thick. The smell wrong. You knew before you even touched it. That's the moment SourdoughKeeper is built for. Log a feeding in two taps. The app calculates your next feed time automatically — 24 hours for room temperature, 7 days for fridge — and flips the countdown the instant you toggle storage. No spreadsheet. No sticky note. No guessing. What's inside: - Feed log — one tap records the feeding. Timestamps stay local, no account needed. - Countdown timer — auto-adjusts when you move your starter between room temp and fridge. Daily reminder lands on your Lock Screen at the time you choose. - Hydration calculator — enter flour weight and target hydration percentage, get the exact water amount. Save presets for your favourite ratios. - Apple Watch app — the same countdown on your wrist with a "Just fed it" button that syncs back to iPhone instantly. - Feeding reminders — daily local notification at your chosen time. No push server. No background pinging. Who this is for: Weekend bakers who have killed at least one starter from neglect. People who bake every Saturday and lose track by Wednesday. Sourdough beginners who want one place to track everything. Experienced bakers who want hydration math done for them. Privacy by design: No account. No sign-in. No cloud. No analytics SDK. No ads. Everything lives on your phone and your Watch. Uninstall and it's gone. SourdoughKeeper Pro: The core feeding log, countdown, and reminders are free. SourdoughKeeper Pro is an optional upgrade that unlocks the hydration calculator presets and extra tools — available as an auto-renewing monthly subscription or a one-time Lifetime purchase. Prices are shown in the app before you buy. — Subscription & Terms — SourdoughKeeper Pro Monthly is an auto-renewing subscription billed monthly.
