Lievanto
Features

Everything the bake needs. Nothing it doesn't.

Lievanto gathers the work that matters for a sourdough or pizza bake: estimating, coaching, planning, and remembering, so each bake builds on the last.

The differentiators

The timing problems Lievanto is built around.

Starter peak window

Log feedings with the ambient temperature. A Q10 temperature model estimates a likely peak window, and the estimate gets more useful as your starter history grows. Confirm with rise, dome, bubbles, and collapse cues.

Bulk fermentation coach

Check the dough with a tap: volume %, jiggle, poke, ambient temp. A likely ready window helps you decide when to shape, even if that's earlier than the clock, and shifts when the kitchen warms up.

Schedule planner

Pick a target, say Saturday 6 pm, and Lievanto works backwards through feed, mix, bulk, cold proof, final proof, and bake. Save the plan, add reminders, and spot awkward overnight steps before bake day.

Troubleshooting guides

Walk a decision tree for a flat loaf, gummy crumb, fool's crumb, pale crust, burst side, or off taste. Land on a diagnosis and a few concrete changes to try next time.

The logbook loop

The more you bake, the better your notes get.

Insights

A 52-week bakes histogram, a streak counter, rating-versus-variable correlations (does 70% hydration really beat 65% for you?), and your top-rated recipes by average rating.

Cook mode

Guided step-by-step with integrated timers and background notifications. Equipment-aware suggestions adapt the recipe to your kitchen, shown next to the original, never silently. Photos and notes captured in-line.

The logbook

Every bake, tied to the recipe it came from. Photos, ratings, and per-bake variables: hydration, ferment hours, flour, oven temp. Nothing forgotten between bakes.

AI Baking Coach

Planned for the paid App Store release: after saving a bake, explicitly ask the optional Coach to analyze the log, read a crumb photo you select, or answer a short question from relevant history. Saving never sends data to AI.

The calculators

A full dough calculator with preferments, a DDT solver, a cold-ferment yeast calculator, pan-size, scaling, and production planning. decimal.js keeps the calculations stable.

What else

The details that add up.

Set up your kitchen

Tell Lievanto your oven (home, stone, steel, or a dedicated pizza oven) and how you mix (by hand, stand mixer, or spiral). Cook mode then tailors temperatures, timings, and step instructions to your setup, shown next to the original, never replacing it.

Measure in your units

Read and enter every amount in the units you think in. Pick a system, metric, imperial, or baker's percentages, or set the unit per ingredient: grams for flour, millilitres for water, teaspoons for yeast. Temperatures in °C or °F.

Weather-aware on iOS

On iOS, kitchen temperature can prefill from local weather when enabled, so yeast and timing estimates start from a more useful number.

Recipe forking

Tweak a copy of any recipe without losing the original, and keep both in your library.

Your data stays yours

Export your account as JSON without Pro. No ads or advertising tracking. The paid App Store release is planned to keep the core workflow Free and add Pro photo backup, comparison, advanced tools, and a higher Coach allowance.
