ProofTime: Sourdough Timer app analytics for September 5

Stop guessing when your bulk fermentation is done. ProofTime calculates your estimated bulk time based on room temperature, levain percentage, and starter activity — then starts a countdown so you can go do other things. One-time purchase. No subscription. Works completely offline. BULK FERMENTATION TIMER Enter your room temperature (°F or °C), how much levain you're using, and how active your starter is. ProofTime gives you an estimated time window and starts a timer. Built-in reminder: "watch the dough, not just the clock." DOUGH CALCULATOR Enter your flour weight and ProofTime calculates exactly how much water, levain, and salt you need — in grams. Adjust hydration (50–100%), levain % (5–50%), and salt % in real time. FEEDING CALCULATOR Choose your feed ratio (1:1:1, 1:2:2, 1:3:3, 1:5:5, and more), enter your desired final weight, and get exact amounts for starter, flour, and water. MY STARTERS Save multiple starter profiles with name, hydration %, and typical activity level. No more mental math about which starter is which. WHO IT'S FOR Home bakers who have graduated beyond basic recipes and want precise, repeatable results. Serious about sourdough — but not about paying $25/year for a calculator. DESIGNED FOR BAKERS • Clear, readable display — easy to glance at with floury hands • All calculations are local — no internet required, ever • Supports both °F and °C • Disclaimer built in: fermentation is biological, times are estimates
