Baker's Percentage Notebook

Hydration, Pan Size & Scaling

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Scale any bread recipe by weight, not guesswork. Baker's percentage math, pan-to-pan volume conversion, and automatic hydration — all offline, no ads, one-time purchase. Ever changed your flour amount mid-recipe and had to redo every other ingredient by hand? Or needed to fit a recipe into a different pan and had no idea how much to scale it? Baker's Percentage Notebook handles both, so the math never gets between you and the dough. ■ Baker's percentage, both directions Set your flour as 100% and track every other ingredient as a percentage of it. Change the flour amount from 300g to 450g and every ratio stays exactly the same — scaling a recipe up or down is instant. ■ Back-calculate from what you have on hand "I have 250g of water and want 70% hydration — how much flour do I need?" Enter the ingredient weight and its baker's percentage, and the app calculates the flour amount for you. ■ Scale to a different pan (round, square, or loaf) Enter the dimensions of your current pan and the pan you want to bake in — in cm or inches — and the recipe scales automatically based on the volume ratio between them. ■ Hydration at a glance Every liquid ingredient (water, milk, and more) is totaled automatically into a hydration percentage, shown right on the main screen. ■ Save your recipes Save a formula with a name and a note, then load it back anytime and adjust it for the day's flour amount or pan (3 free, unlimited with Premium). ■ Premium (one-time purchase) • Unlimited recipe saves, with notes • Custom ingredient names and non-wheat bases (rice flour, whole wheat, and more) • Zero ads on every plan — this was already true for free, Premium doesn't change it ■ Built to be trusted • No ads, ever — nothing gets in the way of your baking math • Fully offline. Every recipe you enter stays on your device and is never sent anywhere • One-time purchase. No subscriptions, no recurring charges
