Detail
How it works
Renaming the button
Open Settings and scroll to the Meter Button card. Tap the text field and type a new name. You can use up to 16 characters. The new label appears on the button immediately after you save. Some examples: 'Shoot', 'Read', 'Meter', 'EV', or your initials.
Choosing a theme
Below the name field are ten colored chips representing different button styles. Tap any chip to preview that theme on the button. Your choice persists when you close Settings.
The ten themes
Crimson (vintage shutter-release red); Material (follows your phone's system theme); Sunset (yellow to orange to red gradient); Carbon (matte black); Phosphor (green text on dark background); Brass (bronze antique); Polaroid (cream label); Cinema (cyan and dark); Bauhaus (bold yellow); Outline (minimal white border).
Why customize it
The button is your most-tapped control. Naming it to match your workflow and choosing a style you like makes the meter feel like your tool, not a generic app. It also makes it easier to teach someone else how to use it: 'tap the red one' is faster than 'tap the button that says Measure Light'.
