Stop stressing about the math. Start enjoying the baking.
We calculate it all correctly. Preferments, levains, poolish—automatic flour and water accounting across every stage.
"I have 500g of flour" or "I need 6 loaves" or "Make this fit my bowl"— BenchProof understands how you actually think.
No more guessing at inoculation percentages. Tell us how much starter you have, and we'll adjust everything automatically.
Need to finish at 8 AM? Or start at midnight? Set your time and watch the schedule flow. Adjust any step and everything updates.
Need fresh bread at 8 AM Saturday? Tell BenchProof when you want to finish, and it calculates every step backwards:
