Custom spectra let you track any two-sided question, habit, preference, or tendency that matters to you.

What you can customise

  • Left label: The left end of the spectrum.
  • Right label: The right end of the spectrum.
  • Category: The group where the spectrum appears on the home screen.
  • Cadence: How often Spectra should consider the spectrum due for a check-in.
  • Starting position: The first saved value for the new spectrum.

Creating a custom spectrum

  1. Tap the plus button on the Spectra home screen.
  2. Enter a left label and right label.
  3. Choose a category.
  4. Choose a cadence.
  5. Set the starting position with the slider.
  6. Tap Save.

Managing categories

Premium users can add, rename, reorder, and delete categories. Category names must be unique and cannot be empty. A category cannot be deleted while spectra are still assigned to it, and Spectra must always keep at least one category.

Editing an existing spectrum

Open a spectrum to update its category or cadence. The history and previous check-ins remain attached to the spectrum.

Deleting or hiding spectra

You can delete a spectrum from the home screen context menu. If you want to keep its data but remove it from regular views, use Settings > Manage Spectrum Visibility and hide it instead.
