Your recipe box

Every calculation you save — a pan conversion for the brownie recipe, flour in grams for the Sunday loaf — kept on this device, reopenable in one tap. Nothing syncs anywhere: the box is yours, so export a backup now and then.

Nothing saved yet — here's how it works

  1. Open any calculator and set up your numbers — say, your brownie recipe's pan conversion.
  2. Tap Save result in the row under the answer.
  3. Find it here next bake, exactly as you left it.

Saves live in this browser only and work offline. Clearing site data clears the box — the export button above is your backup.
