Rise and Grumble
Learn sourdough starter care
$1.99 · Designed for iPad. Not verified for macOS.
Revive a neglected sourdough starter with real-time feeding, temperature changes, helpful graphs, and one very opinionated jar.
Rise & Grumble is a playful sourdough starter trainer that teaches real starter care through a virtual recovery challenge.
Your starter has been neglected. It is acidic, sluggish, dramatic, and absolutely ready to judge your choices. Bring it back to health by choosing feeding ratios, managing temperature, moving it between room temp, warm spots, and the refrigerator, and watching how rise, acidity, and yeast strength change over real elapsed time.
The app helps beginners understand the rhythm of sourdough maintenance without wasting flour or guessing blindly. Feed too little and your starter may stay sour. Keep it cold and recovery slows down. Give it the right care and you will see stronger rise patterns, healthier balance, and progress toward a revived starter.
Features include:
• A virtual starter with attitude
• Real-time fermentation pacing
• Feeding ratio controls
• Room, warm, cool, and refrigerator temperature modes
• Rise, acidity, and yeast strength tracking
• A visual performance graph
• Recovery quest for reviving a neglected starter
• Starter naming
• Reset confirmation
• No account, no tracking, no collected personal data
Rise & Grumble is an educational simulator, not a food safety tool. It is designed to help you learn the habits and timing behind healthy sourdough starter care.
