Leaven: Baker's Percentage

Doing baker’s math by hand is a pain. Spreadsheets aren’t much better. Leaven handles the numbers so you can focus on baking.

It’s a simple app built around baker’s percentages. You enter your recipe once, with all ingredients expressed as a percentage of total flour weight, and it scales cleanly up or down. Whether you’re baking a single loaf or prepping for a pop-up, the math just works.

No signups, no fuss. Just open the app and start baking.

What Leaven does:
- Scale recipes fast — change ingredient weights or percentages, and Leaven updates everything instantly. Dial in a flour weight, total weight, or ingredient weight to scale up and down.
- Save and edit recipes — name your recipes, tweak them anytime, and keep everything organized.
- Track your bakes — Leaven saves a snapshot each time you bake in each recipe's Notebook. Add notes, see what worked, and improve your process.
- Understand your ratios — Leaven speaks in baker’s percentages, with flour always at 100%. You get consistent, predictable results.
- Add notes and variations — keep notes on oven settings, fermentation time, hydration, etc. Duplicate recipes to test new ideas without losing the original.
- Share easily — export recipes in markdown or as Leaven links for other users to import.
- Synced privately — all your data is stored in an iCloud container that only you can access.

If you bake often, Leaven’s a no-brainer. It gets the math out of your way, so you can focus on the bread.
