Tell Crusty when you want to slice. It works backward through the levain, the folds, the shaping, and a night in the fridge, and never needs your hands while you’re asleep or in a meeting.

Try it
It’s Thursday morning. You sleep from 11 to 7 and you’re at work all Friday. Pick a time and watch Crusty fit a country loaf around the week.
These plans come from the same planning engine that runs in the app, with a 21 °C kitchen.
Planning
Pick a time, or just tap Start now. Crusty searches every fridge length and start time for plans that keep your hands free when you’re not.


Two bakes, one oven
Run up to three bakes at once. Crusty plans each around the others, so two never need the oven at the same time, and every reminder says which dough it’s for.

Your calendar
Pick the calendars that matter. Meetings and appointments become time Crusty works around, and your bake can land in a calendar of its own.
While you bake
Cook mode keeps the screen awake and shows one thing: what’s next and how long until it. Reminders arrive on time, and you can log a fold from the Lock Screen without washing up.


Apple Watch and iPad
Crusty on Apple Watch shows what’s next and counts down to it. Tap Folded or Done and your iPhone replans the rest. On iPad, the whole bake sits beside what’s next.


Your starters
Log a feed and Crusty predicts the peak from the ratio and the room. Tap “Record peak” when it does, and every prediction after that gets closer to your jar.

Baker’s percentages
Every recipe is a formula. Make two loaves, push the water to 80%, or switch to a stiffer levain, and the grams and the timing follow. Save it as your own.
💧 Mix with 33 °C water for 25 °C dough.
The library
Each recipe knows its own steps, rises, and cues. Write your own in grams or cups, import one from a link, or open one a friend shares, and Crusty times it like the rest.

Under the hood
Most recipes say “bulk for 5 hours.” Your dough doesn’t know that. Crusty treats every rise as a window that stretches with the temperature and the strength of your starter, then uses the slack to fit your life.
Every 8 °C warmer, fermentation runs about twice as fast. Crusty scales each rise for your kitchen and your dough temperature.
Halve the starter in your levain and it needs roughly one more doubling time. Stiffer feeds wait longer, and the plan knows it.
The fridge is the shock absorber. A cold retard can stretch across a workday or a night so the next step lands when you’re free.
Your bake log
Crusty keeps what really happened: step times, dough temperature, crumb photos, and how it turned out. After a few bakes it tells you what it sees.
“Overproofed bakes averaged 79 °F dough; your good ones 76 °F.” Patterns in plain words, with the numbers behind them.
Compare two bakes side by side: what changed, how long each rise really took, and which came out better.
