Crust is pizza dough math for home bakers — the three things every PizzApp+ review asks for, in one app you buy once. A backtimer that schedules your mix from your bake time. A calculator with hydration / salt / oil / yeast ranges from named sources. A symptom troubleshooter for when the dough is fighting you.

Backtimer Tell Crust when you want to eat. Pick same-day or cold-ferment. Get a timestamped schedule — mix, bulk, ball, final proof, bake. Cold ferment maxes out at 72 hours so the dough doesn't go boozy on you. Yeast percent recommended for the chosen cold-ferment length is shown right on the slider.

Calculator Pick a style and Crust pre-fills hydration, salt, oil, and yeast at that style's defaults. Override anything. Hydration shows a status dot for in-range vs out-of-range against that style's source-cited band — Neapolitan home oven 60–70%, AVPN spec 55.5–62.5%, New York 58–65%, Detroit 65–75%, Sicilian 57–70%, Roman 50–55%. Outputs flour / water / salt / oil / yeast in grams scaled to your dough-ball count and weight. Convert yeast between instant, active dry, fresh, and sourdough starter inline.

Troubleshooter Pick the closest symptom — dough too wet, won't rise, domed in the fridge, smells boozy, dense underbaked, tough and chewy, won't brown. Crust gives a next-time fix and, where possible, a rescue for the batch on the bench right now.

Sources Hydration, salt, and yeast ranges are cited per style — AVPN spec, Tony Gemignani, Ken Forkish, Marc Vetri, Anthony Falco. The 72-hour cold-ferment cap is the fond.kitchen yeast table. Symptom advice is the consensus across PizzaMaking forum threads and the working pizzaiolo community.
