Everything a home baker needs

Feeding log with ratios and photos

Record each feeding with the starter:flour:water ratio (like 1:5:5), grams, a photo and notes. Keep several starters and see how each one behaves.

Mark the rise on the photo

Drag lines to the bottom of the jar and to the top of the starter. Leavenly does the math and shows the rise in percent and as a multiple. You decide where the lines go.

Reminders that follow your kitchen

Tell the app how warm your kitchen is and the feeding interval adjusts by a simple local formula. It is an estimate, and you can calibrate it with your own results.

Questions and answers

Does Leavenly use AI to judge my starter?

No. The rise is marked by you on the photo, and the app only calculates the percentage. We do not scan or upload your photos.

Does it work offline?

Yes. Your data lives on your device. The network is only used for purchases, anonymous usage statistics and opening links.

How accurate are the reminders?

The temperature adjustment is a simple estimate, not a laboratory result. Flour, hydration and starter age also matter, so use the reminder as a guide and trust your starter.

What do I get for free?

One starter with a feeding log and photos, and the baker's percentage and hydration calculator. Premium adds several starters, bake plans with Live Activity, temperature-aware reminders, vacation mode, widgets and all formulas.

How do I cancel the trial or subscription?

On iPhone open Settings, tap your name, then Subscriptions, choose Leavenly Premium and tap Cancel. Cancelling at least 24 hours before the period ends stops the renewal.

Which devices are supported?
