Bread on your schedule. Know exactly what to do and when.

Proofday is a sourdough planner for real life. Pick a recipe, say "bread ready Saturday at 10", and Proofday works backwards from there: when to feed your starter, mix, fold, shape, chill, preheat and bake. Every step gets a reminder, and none of them land while you're asleep. Running late? Tap "Need more time" and the rest of the plan shifts to fit.

PLAN EVERY BAKE
• Works backwards from your ready time, or forwards from "start now"
• Keeps every step out of your quiet hours, using the cold proof and a slower overnight starter feed to bridge the night
• Tells you why a time won't work and offers the nearest one that will
• Reminders you can act on from the lock screen: Done, +15 min, Snooze
• Live Activity and Dynamic Island countdown, plus a fold timer with haptics

KNOW WHEN YOUR STARTER PEAKS
• Peak predictions from the feed ratio and your kitchen temperature
• Rise measured from photos: mark the jar, then line up each check with a ghost of the first photo for a real percentage, not a guess
• Predictions tune themselves to your kitchen over time
• "Make a starter from scratch": a day-by-day program, including the quiet days when nothing seems to happen

FIND OUT WHY YOUR CRUMB WAS DENSE
• Crumb Check reads a photo of your cut loaf together with that bake's real numbers: bulk time, aliquot rise, temperatures
• Says "can't tell" when a photo isn't clear, rather than guessing
• Apply its suggestions to your next bake in one tap

EVERY CALCULATOR A BAKER NEEDS
• Baker's percentages, hydration, recipe scaling, levain builds, and water temperature for your desired dough temperature
• Grams by default, ounces and cups if you prefer, °C or °F

RECIPES AND GUIDES
• Country loaf, open crumb, 30% whole wheat, sandwich loaf, focaccia, bagels, pizza, a gluten-free loaf, and discard pancakes, crackers and flatbreads
• Short guides on shaping, scoring, the aliquot, fridge storage and reviving a starter
• Gluten-free mode, with gluten-free starters and recipes

A JOURNAL THAT LEARNS
Every bake keeps its plan vs actual times, temperatures, photos and Crumb Check, so you can see what changed from loaf to loaf.

Your data stays on your iPhone. No account, no ads, no tracking. Proofday never judges whether a starter is safe from a photo; its safety guide tells you what to look for.
