Sourdough Pet vs S.D Timer

Meet your new best friend: a pixel-art sourdough starter that eats, sleeps, and needs your love. Sourdough Pet turns the daily ritual of caring for a real sourdough starter into a cozy virtual-pet experience. Adopt a starter, feed it on schedule, knead dough to your favorite Spotify tracks, and bake beautiful loaves — all while your adorable pixel pet reacts to how well you care for it. ADOPT & NAME YOUR STARTER Pick a name for your sourdough starter, choose its storage container, and set a feeding schedule that fits your life. Your pet starts as a tiny blob and grows as you level up. DAILY FEEDING Log your feedings with flour type, hydration ratio, and optional notes. Your starter's mood changes based on how consistently you feed it — keep it happy or watch it get hangry. BAKE DAY When your starter is strong enough, it's time to bake! Follow guided phases from mixing to cooling, with a music-powered kneading timer. Connect Spotify and knead to your favorite songs — the timer ensures you knead long enough. YOUR PET REACTS Five moods — happy, content, hungry, sleepy, and neglected — drive your pixel pet's expressions and animations. Idle bounces, sparkle effects, sleepy Z's, and more bring your starter to life. PIXEL ART STYLE Gorgeous retro pixel-art sprites in the classic virtual-pet tradition. Five unlockable pet designs: Blobby, Baguette, Pretzel, Croissant, and Brioche. Each with unique animations for every mood. JOURNAL & STREAKS Track your feeding history on a calendar heatmap and browse a photo gallery of your loaves. Build feeding streaks, earn XP, and level up your starter. KNEADING WITH MUSIC Connect your Spotify account and browse playlists, search for songs, or pick from your favorites. The kneading timer keeps you on track while you jam. PRIVACY FIRST All your data stays on your device. No accounts required, no personal data collected, no tracking. Anonymous analytics help us improve the app — that's it. --- • Feed your sourdough starter daily and watch it react • Knead dough with a Spotify-powered music timer • Five pixel-art pet designs to unlock • Track feedings, streaks, and bakes in your journal • Cozy, offline-first — no account needed

S.D TIMER computes the exact feeding schedule for your sourdough starter, working backward from your target ready time to give you a precise feed time and gram-level recipe. HOW IT WORKS Enter six parameters: target ready time, quantity of starter needed (grams), desired hydration percentage, flour type, starter activity level (%), and ambient temperature (°C or °F). The app applies a fermentation kinetics model that factors temperature-dependent metabolic rates of lactic acid bacteria and wild yeast to calculate when your starter will hit peak activity. OUTPUT — YOUR FEEDING PLAN • Feed time: the exact moment to feed so your starter peaks on schedule • Starter / flour / water quantities in grams • Feed ratio (e.g., 1:9.8:9.8) • Estimated peak pH • Predicted flavor profile (mild, balanced, tangy, complex) • Recommended bread types suited to the resulting starter profile • Fermentation timeline chart with 80% activity window marked Set process alarms directly from the results screen to get notified at feed time and at peak. DESIGNED FOR PRECISION Temperature has a nonlinear effect on fermentation speed. A 5°C difference between summer and winter kitchens can shift peak time by 2–4 hours. S.D TIMER accounts for this so your timing stays consistent regardless of ambient conditions. Supports both Celsius and Fahrenheit. Works across all flour types including whole wheat, rye, spelt, and einkorn. Starter activity input lets you calibrate for your specific culture's behavior.
