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.

Great minimalist recipe calculator

This app is exactly what I’ve been looking for! A bit of a learning curve, but once you sort out the features/UI this app is incredibly powerful. I love that I can track changes to a recipe over time and collect my notes in one place. I often merge a few recipes together and now I’m able to replicate or tweak my results without having to search through 10 different sites. No distracting ads, pop ups, backstories, or affiliate links. You can tell the developer made this for themself first and genuinely wanted to share their project rather than profit off it.

Thanks for the kind words! You’re right - built for myself, and then figured other people might find it useful too. Enjoy.

Took a few minutes playing around to figure it out but once I did it was perfectly helpful. I am an amateur home novice baker so the simplicity of the app was perfect!
